A first look At The Bytecodes Of The Java Virtual Machine

A first look At The Bytecodes Of The Java Virtual Machine

Welcome to another sequel of “Under The Bonnet.” This line gives Java designers a look at what is going on below their operating Java applications. This month’s content takes a first look at the bytecode training set of the Java virtual machine (JVM). The content includes basic kinds managed upon by bytecodes, bytecodes that turn between kinds, and bytecodes that managed with the collection. Following content will talk about other individuals the bytecode family.

The bytecode format

Bytecodes are the device terminology of the Java exclusive device. When a JVM plenty a category computer file, it gets one flow of bytecodes for each strategy in the course. The bytecodes sources are saved in the process area of the JVM. The bytecodes for a strategy are implemented when that strategy is invoked during the course of operating this method. They can be accomplished by intepretation, just-in-time obtaining, or any other strategy that was selected by the developer of a particular JVM.

Bytecodes Of JVM

A method’s bytecode flow is a series of guidelines for the Java exclusive device. Each training includes a one-byte opcode followed by zero or more operands. The opcode indicates the course of activity. If more details are required before the JVM can take the activity, that details are secured into one or more operands that instantly adhere to the opcode.

Each type of opcode has a mnemonic. In the common set up terminology design, sources of Java bytecodes can be showed by their mnemonics followed by any operand principles. For example, the following flow of bytecodes can be taken apart into mnemonics:

The bytecode training set was made to be lightweight. All guidelines, except two that deal with desk moving, are arranged on byte limitations. The count of opcodes is sufficiently little so that opcodes take up only one byte. This allows reduce the dimension sophistication information that may be journeying across systems before being packed by a JVM. It may also help keep the dimension the

JVM execution little.

All calculations in the JVM focuses on the collection. Because the JVM has no signs up for saving abitrary principles, everything must be forced onto the collection before it can be used in a calculations. Bytecode guidelines therefore function mainly on the collection. For example, in the above bytecode series a regional varying is increased by two by first forcing the regional varying onto the collection with the iload_0 training, then forcing two onto the collection with iconst_2. After both integers have been forced onto the collection, the imul training successfully bursts the two integers off the collection, increases them, and drives the consequence back again onto the collection. The outcome is jumped off the top of the collection and saved returning to the regional varying by the istore_0 training. The JVM was made as a stack-based device rather than a register-based device to accomplish effective execution on register-poor architectures such as the Apple 486.

Basic types

The JVM facilitates seven primitive information kinds. Java developers can announce and use factors of these information kinds, and Java bytecodes function upon these information kinds. The primitive kinds appear as operands in bytecode sources. All primitive kinds that take up more than 1 byte are saved in big-endian purchase in the bytecode flow, which implies higher-order bytes come before lower-order bytes. For example, to force the continuous value 256 (hex 0100) onto the collection, you would use the sipush opcode followed by a brief operand.

Java Is A Dead-End For Enterprise App Development

Java Is A Dead-End For Enterprise App Development

Before Java was developed, one of the key industry styles was to increase the efficiency of both designers and end customers. For example, fourth-generation development ‘languages’ (4GL) such as Powerbuilder, Improvement, and Uniface offered expert designers with quicker ways to build up company programs than using COBOL, Pascal, C, or C++. For end customers, resources such as Dbase, Lotus Notices, and Visicalc offered them with the unmatched ability to create mini-apps without the need for expert designers. In the early ’90s, this efficiency pattern was tossed into a tizzy by the Online. Now, application providers and company program designers had to hurry to create a whole new creation of programs for the Web or risk becoming unrelated. The Online pressured designer efficiency and 4GL’s to take the back chair.

Java Was At The Right Place At The Right Time For Web Applications

Java was developed in 1990 as an easier and more convenient option than C++ to build up included techniques. The advancement of the WWW in 1993 started a meteoric alternation in IT database integration. Sun Microsystems shifted quickly to take advantage by selling “network” web servers like pancakes and providing Java as system for Web design. Most other application providers were captured off secure and Java became the de facto Online growth standard for company Web database integration.

Fast-Forward 20 Years

Forrester information shows that Java is still strongly placed in company IT stores for custom-developed programs (see figure). But, information always informs us what actually occurred in the past and does not estimate the long run. Application designers should also not make the big error that adopting means benefits.

Java is not going away for company programs, just as COBOL is not going away. Java is still your best option for app dev groups that allow us the framework and skills to build up and maintain company programs. It is also an excellent option (along with C#) for application providers to build up resources, resources, and techniques such as BPM, CEP, IaaS, and flexible caching techniques (ECP). Software such as operating-system, data source, and system games are still mostly developed in C++.

Java Has Provided Its Purpose, But Now It Is Time To Move Forward

Java growth is too complicated for company database integration. Enterprise database integration groups should plan their get away from Java because:

Business specifications have modified. The interest rate of modify has improved.

Development publishing is restricted to development ‘languages’. Even though the Java system facilitates additional development ‘languages’ such as Cool and JRuby, the actual system boundaries advancement to the standard services offered by Java. You can develop as many new development ‘languages’ as you want, but they must all be implementable in the actual system.

Java bungled the demonstration part. Move is a headache and JavaFX is failing. JSF was developed for pre-Ajax user connections even though some implementations such as ICEfaces integrate Ajax. There is a stable flow of new UI techniques showing Java’s lack of management in the demonstration part.

Java frameworks confirm complexness. Hibernate, Springtime, Struts, and other frameworks expose Java’s inadequacies rather than its strong points. A upcoming system must not need a cacophony of frameworks just to do the fundamentals.

Java is based on C++. Is this really the best way to build up company business applications?

Java’s new manager is the same as the old manager. Oracle’s rule is unlikely to improve Java. Oracle’s latest Java reports were a frustration. They are concentrated on more features, more efficiency, and more relationships with other providers. So far, this indicates that Oracle continues with Sun’s same unsuccessful Java guidelines.

Java has never been the only game in town. C# is not the alternative. It is little more than Java Microsoft company style. But, there are new designer resources such as Microsoft company Lightswitch and WaveMaker — and conventional but modified 4GL resources such as Compuware Uniface and Improvement OpenEdge. And don’t forget about company guidelines techniques, company process management (BPM), and event handling techniques which allow quicker modify offer by company application providers such as IBM, Improvement, TIBCO, Software AG.

An overview of datastructures in Java

The data structures given by the Java system program are very powerful and perform variety of functions. These details elements include the following client customer interface and classes:

1. Enumeration
2. BitSet
3. Vector
4. Stack
5. Dictionary
6. Hashtable
7. Properties
The Enumeration:

The Enumeration client customer interface isn’t itself an understanding framework, but it is very essential within the viewpoint of other details elements. The Enumeration client customer interface explains a strategy to get better following elements from an understanding framework.

For example, Enumeration explains a technique known as next Element that is used to get the next look at an understanding framework that contains several elements. This heritage interface has been superceded by Iterator. Although not deprecated, Enumeration is regarded outdated for new rule. However, it is used by several techniques described by the heritage sessions such as Vector and Qualities, is used by several other API sessions, and is currently in extensive use in program rule.

To have more details about this client customer interface, analyze The Enumeration.

The BitSet

The BitSet classification uses several bits or banner ads that can be set and removed individually.

This classification is very useful in the case where you need to keep up with a set of Boolean values; you just spend a bit to each value and set or clear it as appropriate.

To have more details about this classification, analyze more about The BitSet.

The Vector

The Vector classification is identical to an ordinary Java variety, except that it can produce as necessary to assist new elements.

Similar to an array, elements of a Vector product may be used via a selection into the vector.

The amazing thing about using the Vector classification is that you no problem about developing it to a particular dimension upon creation; it cuts down on and produces immediately when necessary.

To have more details about this classification, analyze more about The Vector.

The Stack

The Collection classification uses a last-in-first-out (LIFO) assortment of elements.

You can think of a selection generally as a directly assortment of objects; when you add a new aspect, it gets placed on top of the others.

When you take an element off the gathering, it comes off the top. Simply, the last aspect you involved to the gathering is the first one to return off.

To have more details about this classification, analyze The Collection.

The Dictionary

The Terminology classification is a very subjective classification that explains an understanding framework for implementing tricks of concepts.

This is useful in the case where you want to be able to obtain availability details via a particular key rather than an integer selection.

Since the Language classification is very subjective, it provides only the framework for a key-mapped details framework rather than a particular performance.

To have more details about this classification, analyze The Language.

The Hashtable

The Hashtable classification provides a way of preparing data based upon on some user-defined key framework.

For example, in a cope with list hash table you could shop and kind details based upon on a key such as ZIP concept rather than on a person’s name.

The particular goal of key elements with regards to hash systems is very dependent on the make use of the hash table and the details it contains.

To have more details about this classification, analyze The Hashtable.

The Properties

Properties is a subclass of Hashtable. It is used to keep data concepts in which the key is a String and the value is also a Sting.

The Features classification is used by many other Java sessions. For example, it is the kind of product came returning by System.getProperties( ) when obtaining environmental concepts. To know more about this go through the data structure tutorial.

Learn java programming | Short Introduction to Java

Learn java programming | Short Introduction to Java

If you are really interested to learn Java then you are at the right place because here in this article you will find an overview of Java basics over here. So here it is a provision for you for as a self guided version. There would be plenty of code examples as you move ahead with this article.

This first article presents the Java system and describes the distinction between its three editions: Java SE, Java EE, and Java ME. You’ll also learn about the part of the Java Virtual Machine (JVM) in implementing Java applications.

A general purpose and an object oriented language that looks a lot like C and C++ but is easier to use and allows you to create more programs.

A network-savvy language: TCP/IP network protocols like HTTP and FTP and it can be easily coped up with extensive network library of Java. And they can access the URLs in an easy way as if its is a normal file.

Java is a robust language: Java programs must work because they are used in both client and mission-critical programs, different from Blu-ray players to vehicle-navigation or air-control techniques. Language functions that help make Java effective statements, duplicate type confirming at compile time and play-back, real arrays with computerized extensive variety confirming, and the omission of pointers.

Java is a convenient language: Structure neutrality leads to mobility. However, there is more to Java’s mobility than platform-independent bytecode guidelines. Consider that integer type sizes must not differ. For example, the 32-bit integer type must always be finalized and take up 32 bits, regardless of where the 32-bit integer is prepared (e.g., a system with 16-bit signs up, a system with 32-bit signs up, or a system with 64-bit registers). Java’s collections also play a role to portability.

Java is a multithreaded language: To improve the efficiency of programs that must achieve several projects at once, it facilitates the idea of threaded efficiency. For example, a program that controls a Graphical User Interface (GUI) while patiently awaiting feedback from a system relationship uses another line to perform the delay instead of using the standard GUI line for both projects. This keeps the GUI responsive.

Java is a secure terminology: Java applications are used in networked/distributed surroundings. Because Java applications can move to and perform on a network’s various systems, it’s important to protect these systems from harmful code that might spread malware, grab bank card information, or perform other harmful functions. Java terminology functions that support sturdiness (like the omission of pointers) work with protection measures such as the Java sandbox protection model and public-key security.

Java is a high-performance language: Presentation results in a level of efficiency that is usually more than adequate. For very high-performance application circumstances Java uses just-in-time collection, which examines considered bytecode training series and gathers frequently considered training series to platform-specific guidelines. Following efforts to understand these bytecode training series result in the performance of equivalent platform-specific guidelines, leading to an efficiency boost.

Java is an object-oriented Programming (OOP’s): Java’s object-oriented concentrate allows developers work on adjusting it to resolve an issue, rather than pushing us to control the issue to meet terminology constraints. This is different from an organized language like C. For example, whereas it allows you concentrate on bank consideration objects, C requires you to think independently about bank consideration state (such a balance) and actions (such as deposit and withdrawal).

Sun fixed the submission issue by considering Java into three main versions. These gradually became known as Java SE, Java EE, and Java ME:

Java System, Standard Edition (Java SE) is the Java platform for creating client-side applications, which run on desktop computers, and applets, which run in internet explorer.

Java System, Enterprise Edition (Java EE) is the Java platform designed on top of Java SE, which is used specifically to build up enterprise-oriented server applications. Server-side applications include servlets, which are Java applications that are similar to applets but run on a server rather than a customer. Servlets adjust to the Java EE Servlet API.

Java System, Small Version (Java ME) is also designed on top of Java SE. It is the Java platform for creating MIDlets, which are Java applications that run on mobile information gadgets, and Xlets, which are Java applications that run on included gadgets.

A shortnote on Java8 and its default interfaces

As Java evolved over the years, the connections presented in the Java library require adding new performance. If you add new techniques in the interface without having standard techniques function, all the sessions that already implemented the connections should go through a modify. This results in changing thousands of lines of code. To avoid this, the Java 8 presented the standard technique function. That is, if you want to add any performance to the current interface, you can add it by using the standard technique function without affecting the implementations.

Let us see some examples to understand this better. For example, I am declaring “BookInterface” with start and look functionalities. The execution sessions of this interface should provide the and look technique implementations.
package org.smarttechie;
// The interface is intended to open and read. The implementors should implement the methods to open and read.
// @author Siva Prasad Rao Janapati
public interface BookInterface {
// This method opens the book
public void openTheBook();
// The method reads the book
public void readTheBook();
}
Now, we will offer the execution to the above interface.
package org.smarttechie;
// The JavaBookImpl is the implementation of BookInterface
// @author Siva Prasad Rao Janapati
public class JavaBookImpl implements BookInterface {
// This opens the book
@Override
public void openTheBook() {
System.out.println(“The Java book is opened”);
}
// This reads the book
@Override
public void readTheBook() {
System.out.println(“Reading the Java book”);
}
}
Now we want to provide near performance to the guide interface.
If you add near performance to the guide interface, the current execution class should go through a modify. With the standard technique function, we can add near performance to the guide interface. The standard technique will be available to all the implementations.

package org.smarttechie;
// The interface is intended to open and read. The implementors should implement the methods to open and read.
// @author Siva Prasad Rao Janapati
public interface BookInterface {
// The method opens the book
public void openTheBook();
// The method reads the book
public void readTheBook();
// The default method implementation
public default void closeTheBook() {
System.out.println(“Closting the book”);
}
}
package org.smarttechie;
// The JavaBookImpl is the implementation of BookInterface
// @author Siva Prasad Rao Janapati
public class JavaBookImpl implements BookInterface {
// This opens the book
@Override
public void openTheBook() {
System.out.println(“The Java book is opened”);
}
// This reads the book
@Override
public void readTheBook() {
System.out.println(“Reading the Java book”);
}
public static void main (String[] args) {
BookInterface bookInter = new JavaBookImpl();
//Call the default method declared in BookInterface
bookInter.closeTheBook();
JavaBookImpl book = new JavaBookImpl();
book.closeTheBook();
}
}

Do I need to learn Java for Hadoop?

People regularly ask me if it’s necessary to have Java development abilities in order to type in the interesting world of Hadoop. When I begin to describe, I’m often met with a frustration and a feeling of restriction upon studying that Java and Hadoop do, in fact, go hand-in-hand. Let me start by saying that the response to the query “Do I need to know Java to understand Hadoop?” is not a easy one. But I digress; the long run of Hadoop is shiny, and moving ahead, no specifications should be seen as restrictions or hurdles, but rather as ways to enhance your abilities and become more professional in your work. As you make your way through this, Hopefully I will be able to describe your issues, and help get you on your way to quality within Hadoop.

To get to the base of this query it’s necessary to look into the record of Hadoop. Hadoop is Apache’s open-source platform; designed to shop and procedure loads of information (orders of petabytes). It happens to be designed in Java. (Personally, I see the terminology choice as merely random.) Hadoop was initially designed as a subproject of “Nutch” (an open-source search engine). It was later designed and would go on to become Apache’s most important venture. At the time this was all occurring, the Hadoop designer group was more relaxed with Java than any other terminology.

Let’s proceed to must program

Hadoop resolves large information systems difficulties through the mature idea of allocated similar handling, but techniques it in a new way. Hadoop provides a structure to build up allocated programs, rather than fix every problem. It requires away areas (such as device problems, allocated procedure control etc.) of saving and handling the information in a allocated atmosphere because they build the primary components: HDFS and MapReduce, respectively.

HDFS is an allocated data file program that controls information storage space. It shops any given computer data file by breaking it into set dimension models known as “blocks.” Each prevent is saved on any device in the group. It provides high accessibility and mistake patience through duplication (think of it as duplication) of these prevents on different devices on the group. Regardless of all these complications, it provides a easy data file program abstraction so that the consumer need not worry about how it shops and operates.

Performance of Java vs C explained over here

Java is the formal development language of Android operating system and it is the foundation for many elements of the OS itself, plus it is found at the main of Android’s SDK. Java has a couple of exciting qualities that make it different to other development ‘languages’ like C.

First of all Java doesn’t (generally) gather to local device system code. Instead it gathers to medium difficulty terminology known as Java bytecode, the training set of the Java Virtual Machine (JVM). When the app is run on Android operating system it is implemented via the JVM which consequently operates the system code on the local CPU (ARM, MIPS, Intel).

Secondly, Java uses computerized storage control and as such utilizes a Garbage Collection (GC). The idea is that developers don’t need to bother with which storage needs to be released as the JVM will keep a record of what is required and once a area of storage is no longer being used the rubbish enthusiast will 100 % free it. The key advantage is enterprise run time storage leaking.

The C development terminology is the complete reverse to Java in these two aspects. First, C system code is collected to local device system code and doesn’t require the use of an online device for presentation. Second, it uses guide storage control and doesn’t have a rubbish enthusiast. In C, the developer is required to keep a record of the things that have been assigned and 100 % free them as and when necessary.

There are other variations between the two ‘languages’, however they have less of a positive change of the specific stages of efficiency. For example, Java is a product focused language, C is not. C is intensely dependent on suggestion mathematics, Java does not. And so on.

Performance

So while there are philosophical style variations between Java and C, there are also efficiency variations. The use of an online device contributes an additional part to Java that isn’t required for C. Although using an online device has its benefits such as high mobility (i.e. the same Java based Android operating system app can run on ARM and Apple gadgets without modification), Java system code operates more slowly than C system code because it has to go through the additional presentation level. There are technological innovation which have decreased this expense to the barest lowest (and we will look at those in a moment), however since Java applications aren’t collected to the local device system code of a device’s CPU then they will always be more slowly.

The other big aspect is the garbage collection. The problem is that rubbish selection needs time, plus it can run whenever you want. This means that a Java system which makes lots of short-term things (note that some types of Sequence functions can be bad for this) will often induce the rubbish enthusiast, which consequently will reduce the system

Java’s risk got fixed within in one and a half year

In July 2013, protection company Security Research found a security risk in Java 7u25 by which an enemy could completely evade the Java sand pit. Oracle launched a spot in upgrade 7u40, but as Security Research declared a few months ago, the spot only resolved the evidence of idea, and a simple rule adjustment still reveals the risk. Moreover, following research has exposed that the weeknesses is even more serious than originally exposed. After the problem became public, Oracle launched a spot as part of 8u77.

The risk can be seen in the new representation collection, available since Java 7, and more specifically in the new MethodHandle classification used for dynamically obtaining and invoking methods. It is related to the way sessions packed by different ClassLoaders are handled. Understanding of the problem needs some basic knowledge ofthe way Java ClassLoaders work; since classification running is one of the least recognized elements of Java, we will start working on give an intro to this idea prior to describing the problem itself.

Java ClassLoaders

Java has the capacity to fill rule dynamically at playback from a variety of resources. The actual through a special type of sessions called ClassLoaders. A standard Java execution might offer several ClassLoaders to fill sessions from data system, a URL, or a zipped computer file, among others, but also provides designers the capability to create their own customized ClassLoaders to handle customized specifications. The regular way to have interaction with a ClassLoader is by contacting its loadClass(String) method, which will agree to the name of a classification, and either return the associated Class item if found, or toss a ClassNotFoundException otherwise. Every classification in a Java application is packed this way by one ClassLoader or another.

Different ClassLoaders can be linked to each other to form a structure by giving a father or mother ClassLoader. If no mother or father is allocated, parents ClassLoader is late to the one that packed this particular ClassLoader (ClassLoaders are sessions themselves, and therefore need to be packed by some ClassLoader). When a father or mother ClassLoader is present, the standard behavior of a ClassLoader is to try to assign the running of the asked for classification to its parent; only if parents (or some grandparent) cannot fill the course, will this ClassLoader attempt to fill the asked for classification itself. However, makers of customized loaders are not required to apply this standard behavior, and they could choose to apply a different one.

5 Myths About Embedded Java

1. Java is slow.

Back in 1995, when Java was first launched, the Java exclusive machine (JVM) used very simple methods internal to run rule. All bytecodes were interpreted; line synchronization was basic, and storage control simple.

With over 20 years of growth, everything has shifted on so that the JVM now uses flexible selection and much more innovative line control, with a variety of pile templates and garbage-collection methods to choose from (including a pauseless enthusiast in the Zest JVM from Azul).

2. Java is dead.

The death of Java has been prediction almost since it was first launched, but it reveals no indication of passing away or even decreasing in its reputation. A look at factors such as the TIOBE catalog or the RedMonk Development Terminology Positions continually reveals Java as the number one or two language used by designers.

3. Java is freed from charge.

Strictly discussing, Java is not 100 % free (because Java is gradually just a trademark). What was the Sun (and now the Oracle) execution of the Java Development Kit (JDK) was launched under a GPL certificate (with Classpath exception) at the end of 2006. This is the OpenJDK venture and, since Java SE 7, has been the referrals execution for the Java SE requirements, as described through the Java Group Process (JCP).

4. Java does not experience from memory leaking.

In ‘languages’ like C and C++, the designer is accountable for all storage control, both assigning and clearly signaling that it’s no more needed (through phone calls like malloc and free). Java has automated storage control. When an item is instantiated, the JVM allocates area for it on the pile. When the program rule no more has any sources to an item, its area can be recycled by the rubbish enthusiast that operates regularly without anyone’s knowledge.

The key point here is that, in order to be garbage-collected, all sources must be eliminated. If a software preserves sources to factors even when they’re not needed and keeps assigning more factors, this will have the same effect as a storage flow in the conventional sense. Eventually, the JVM will run out of 100 % free storage to spend to new stuff.

5. Multi-threading in Java is difficult.

Before Java SE 5, this would have been a reasonable opinion. To create supportive multi-threaded rule, you only really had four APIs to work with (from the Thread class): wait, sleep, disrupt, and inform. This was difficult to get right.

To make life easier, the Concurrency resources (designed by Doug Lea, Lecturer of Computer Technology at New You are able to University) were included to the standard category collections. This offered higher-level abstractions such as semaphores, mutexes, read-write hair, and nuclear functions. Since then, some new APIs have been included, as well as improvement the fork-join structure for specific, recursively decomposable problems.

The existence of Java vulnerabilities is proved

More Microsoft windows customers are setting up areas, but the Oracle Java and The apple company QuickTime issues are even more intense than they were last season, according to Secunia reviews on the 2010 first one fourth. Individuals may think their PCs are protected because they are working Microsoft company windows Upgrade, but most are still at threat because of risk in third-party applications.

Secunia’s figures are based on Microsoft windows PCs working its free Personal Application Examiner, so they only signify a part of the market. Because PSI encourages individuals update insecure software, most non-PSI customers are probably in a more intense place.

In the January-March one fourth, 93.9 % of UK customers had repaired their Microsoft windows based pc, and 96.2 % had repaired other Microsoft software, such as Microsoft Office (PDF). However, 11.9 % still had unpatched third-party software. The figures for the USA were a little bit worse: 93.5 % had repaired the OS, 96.1 % had repaired other Microsoft software, and 12.7 % had unpatched third-party software

The significant issues are Apple’s QuickTime and iTunes, Oracle Java JRE, and Adobe Audience.

In the UK, for example, unpatched Java set ups risen from 36 to 41 % in contrast to the first one fourth of last season, and unpatched QuickTime set ups improved from 55 to 61 %. Luckily, for most customers, both applications can be removed without a important charge. (Adobe Innovative Package customers may have a QuickTime issue.)

Java is a long-running issue, but things may enhance. Oracle has been pressured by the US FTC to apologise for misleading customers about its protection up-dates, and it has been required to weblink to something that uninstalls old editions.

Adobe Audience is another long-running problem: it had 121 weaknesses, which is almost as many as The apple company iTunes (130). Unfortunately, more than 50 percent the Adobe Audience set ups were unpatched.

QuickTime for Microsoft windows is a increasing issue because The apple company has lastly given up on it. Unfortunately, many customers may have skipped the protection signals, eg from US-CERT.

In its full review, available free on demand, Secunia mentioned at Microsoft company offered 67 % of the Top 50 programs running on PCs but third-party programs experienced 79 % of the weaknesses. (The table below reveals the 20 most-commonly set up programs.)

In the Top 50 programs, areas were already available for 84.6 % of the weaknesses found, and there were 23 zero-day weaknesses, in comparison to 20 in 2014.
