10 Important Reasons To Learn Java Programming Language

Let us see 10 reasons which explain the best programming opportunities in terms of development, opportunities and community support.

1) Java is Simple to learn :

This is a surprising quality of Java for making it the best programming language. If there is a steep learning curve it will be very much tough for acquiring the productivity with short life with most of the job oriented project. The English is quite fluent in Java-like syntax with less magic characters eg: Generics angle brackets which makes it simple for reading Java program and learn it quickly.

2) Java is regarded as an Object Oriented Programming Language :

Java is quite famous for this reason as well. It is very simple to develop OOP application and it also assists to keep the modular system extensible and flexible. After having knowledge of key OOP concepts like Encapsulation, Abstraction, Inheritance, and Polymorphism and along with this you can use Java.

3) Rich API is present in Java :

Rich API is another reason for Java programming language’s awesome success which is quite significant with respect to Java installation. After initiating the Java programming for using the code Applets, in those days, offers great animation capability which surprises new programmer who actually uses coding in editor and Turbo C++.

For utilities, I/O, networking, database connection, XML parsing is offered by Java. Open source libraries cover the leftovers like Google Guava, Apache Commons, Gson, Jackson, Apache POI, etc.

4) Strong development tools eg: Netbeans, Eclipse :

For making Java as one of the most used programming languages there is a major role played by Netbeans and Eclipse. If coding is done with Notepad or DOS Editor, coding in IDE is a pleasure. Code completion is quite assisted by them and apart from that they also offer strong debugging capability which is important for real-world development.

5) Great collection of Open Source libraries :

Java can be used everywhere with the help of Open Source libraries. Google, Apache and other companies have offered lots of great libraries which makes Java quite simpler, faster and cost-effective. There are lots of frameworks like Struts, Spring, Maven which makes sure that Java development keeps track of best practices of software craftsmanship for assisting and promoting the Java developers for getting their job done.

6) Wonderful Community Assistance :

The Java programming is the biggest platform and language which has a strong and thriving community. Irrespective of how good the language is if there is no assistance from the community it will not be successful.

Java is quite lucky as there are lots of active forums, StackOverflow, open source organizations and various Java user groups for assisting everything.

The beginners are assisted by the community apart from that even the advanced and the professional Java programmers are helped.

7) Java is FREE :

Free things are always appreciated therefore if an organization wants to use the technology or if the programmers need to learn the programming language the most significant factor is the COST. Since Java is free from the initial state that is you don’t require to pay anything for developing Java application.

8) Amazing documentation support- Javadocs :

When Javadoc was seen at first, I was surprised. The documentation is quite great which explains lots of things about Java API. Without the requirement for Javadoc documentation, there will not be any fame in Java and it is one of the excellent piece of documentation which explains the reason behind the success of the programming language.

9) Platform Independence is present in Java :

Java got quite famous in the 1990s because of this reason. The concept of platform independence is the best and Java’s tagline Write Once Run Anywhere and there are lots of new development in Java.

How To Improve Java Programming Skill?

There is a common question in Java asked by most of the beginners that is how to enhance the Java programming skills. The theoretical concepts are simple to grasp at the time of solving real-world issues which are quite difficult. The actual reason is there was no clear understanding of the concept with real-world links. Here we will see how to enhance the Java Programming skills and become a successful Java developer.

1) Understand the basic of OO

For becoming a better programmer you need to get to know about the perfect data structure algorithms, Design patterns, and OO principles. If you want to become a Java developer then it is a must to know the basics of OO well. Please ask such questions:

-Explain objects in Java and how it relates to the real world?

-Explain inheritance and what do you mean by is a relation and has a relation?

-Explain inheritance and its use? How to implement it in the real life?

2) Read Books

Wherever you go it is not possible for you to replace a good book and it will definitely explain you the concepts in a simpler way by linking it with real-world objects. There are great programming skills present in the authors and simply by reading the books you are getting to know someone’s experience. You can find the most practical authoritative guidelines present in this book with no previous experience.

3) Keep Practicing

It is not possible for you to become an excellent programmer just by getting to know a book. You can very well talk about the bookish theory concepts. You can understand the language limitations or design by best practices only at the time of coding. Therefore to become a programmer you have to be writing lots of code.

4) Enhance the core APIs

The core APIS are to be mastered if you want to become an excellent Java programmer in java.lang.*, java.io.*, java.util.* etc. Irrespective of the type of framework you are using you must have a strong knowledge of Servlets.

5) Invest a good amount of time in analyzing the problem

Before initiating your code, invest lots of time in getting to know and understand the designing solutions and problems. It is possible to make the remaining things simpler. After doing this if any error happens then just fix it.

6) You get to know more by helping others

Just go for online technology forum subscription by giving to Open Source projects like StackOverflow and start communicating with real programmers. Put forth your questions and also reply them by other forum members. Just have a look at the open source java projects at GitHub.

7) Keep it simple

Keep the code logical and understandable and don’t make ti complete for proving the capability to write such codes. Things go well with simple but logical codes which resulted in lesser issues and is quite extendable.

8) Follow good blogs

This world is not only for you where you can find lots of enthusiastic people who face the same technology in the world and blogging their thoughts on the technology. Programmers write the blogs and most give their personal point of view and experience. It is possible to view good and bad of a technology.

9) Update yourself with Java’s latest technologies

Open source frameworks keep evolving in Java and after you start working on a framework it may become some brand new framework which is obsolete and may come with super-set of features.

Java Developer Must Know These 10 Programming Skills

Among various popular programming languages, you can find the apt one is JavaScript and other languages include Python, Ruby etc. Such languages have already put their mark in building scalable web applications. Let us see the important developer skills everyone needs to know:

1) Brush up on JavaScript :

Currently, developers who have gained significant knowledge in JavaScript cannot go wrong as per the survey. The repetitively wanted skill is none other than the proficiency in JavaScript by recruiters and executives. There are employers who search for some top keywords and this impression is already present in most of the developers while a job interview preparation.

2) Go big with data :

In the coming years, it is not possible for the big data projects to get better and it cannot be slowed down. There are lots of years, where big data has been around for and it is a trend which is still staying. There must be a deep knowledge of analytics products, machine learning tools that must be present with the developers and other solutions for transfer, store and combining large amounts of data.

3) The full stack is mastered :

Full-stack developers are sought by lots of top firms who swiftly move between lots of platforms and technologies. The implications of technical decisions are understood by these engineers from core layers of the software onto the presentation layer. The job is done quite effectively done with great assets and will avoid the startup from creating silos by following a classical hierarchical technical decision-making.

4) Buy into DevOps :

The use of cloud computing continues for growing rapidly within the corporations as thought by the wayside tech gurus. The skills of devops are a clear stand-out which is often expressed by the dicta Engineers meant for writing an application with the same engineers who handle the application in production. The engineering silos are broken down by the requirement such that engineers get to know about their code working in production and are apt for stability and performance at the time of development phase.

5) Diversify :

When compared to a few years ago, the skills companies currently are quite varied where Java and C# are a part of the market but when you focus on companies after the last recession you are viewing lots of Python/Django, Ruby on Rails, Node.ks and the review of functional programming languages with Scala that is quite apt.

6) Use the source :

In particular for freelancers, the ability to point to your code on GitHub shows that your work has been put to good use and reviewed by your peers. Libraries which are meaningful are worked on along with open-source for exhibiting the instantaneous value, especially for potential employers by including the contribution to open source projects for assisting the collaboration credentials.

7) Be agile and develop your teamwork skills :

Coders are involved in the Agile development with lots of skills in 2016. One must have the inquisitiveness and be aware of the agile and lean methodologies with the ability to split big projects into change adaptation and delivering the apt quality.

8) Get secure :

In the previous year, the companies that did not attain success are aware that what skills are actually best suited for them. For enhancing security, they are considering lots of proactive approaches which is not inside their IT department but among the board.

9) Go mobile :

For those who can give away their distributions on a wider scale, mobile developers are sought on a higher scale. A successful mobile development is not succeeded via a particular technology skill set but instead via business savvy.

Some Basic Concepts Of Java Programming

There are lots of programmers who are interested in the Java programming language. Java is blowing away the storm. The fastest growing programming language and is a phenomenal success. There are lots of hype about Java and what it has to do. There are lots of confusion with respect to the Java topic.

Java is regarded as a life-changing language

There are other programming languages as well which has the properties of making Java attractive. For few applications, many languages are most suitable. But all those properties are brought together by Java in one language.

Let us see these properties in detail:

-object-oriented

-portable

-multi-threaded

-automatic garbage collection

-secure

Object-oriented:

Java is regarded as an object-oriented language and an object language deals with objects. Code (methods) and data (member variables) are present in objects. There is a particular class to which each object belongs which is a blueprint that explains the methods and member variables of an object. There is a need for a different way of thinking for object-oriented programming but it is quite good enough to design software when compared to procedural programming. There are famous object-oriented languages that are present today. Java and Smalltalk are developed from the starting to be object-oriented.

Read More: Explain The OOPs Concept In Java

Portable:

For a particular operating system and processor architecture, there are lots of programming languages developed. After the compilation of source code, it is transformed into machine code which can be workable only on a particular type of machine. There is an interpretation of one more type of language. There is no need to compile the interpreted code and as it is running it is translated. This is the reason behind why the interpreted code is quite slow but it is often portable among various operating systems and processor architectures.

Multi-threaded:

Either using PERL or C if complex applications are written you would need to come across the idea of multiple processes before. There are separate copies into which an application can be split which runs concurrently. Code and data are replicated by each copy which leads to increased memory consumption. It would be frustrating and quite complex by getting the copies to communicate together. The operating system is called by involving each process creation which takes up extra CPU time as well.

It is apt to use multiple threads of execution, referred as threads for short. Data and code can be shared by a thread and it has been made simple to share data between thread instances. Less memory is used by them along with CPU overhead. There are few languages similar to C++ for assisting the threads but they are quite complex to use. There are multiple threads of execution built into the language. A different way of thinking is needed by the threads but it can be understood more soon.

Automatic garbage collection:

We are not just limited to trash and reclamation of unused memory is the term garbage collection actually means. Memory space is allocated by JVM when the application creates objects for their storage. When there is no need for objects than for a later use the memory space can be reclaimed.

In programming languages like C and C++ the programmer needs to allocate and deallocate memory manually or else the memory space will be reduced but such worries are not there at the time of using Java.

Secure:

In Java security is considered a big problem because Java applets are downloaded and executed remotely in a browser there is an increased security concern.Everyone wants their documents to be safe. You can find strong security restrictions at the API level and network access for applets along with support for digital signatures for checking the downloaded code’s integrity. There are frequent checks being done at the bytecode level. The only issue is with the JVM link as it prone to attacks but then need not worry it can be easily fixed.

Important Features Of Java That Every Developer Must Know

We will check over here for the new release of Java that is JDK 10. It is very much required currently and you can download it now on Oracle’s Website. This is regarded as the first release of the new release schedule where you have a new Java release every six months and it is a known fact that it is quite early currently in reality. It is not just limited to the 6 months release because every 3 years there is an LTS release which is similar to a major Java release.

1) Time-Based Release Versioning (JEP 322) :

A new schedule has been adopted by Java from JDK 10 release for every six months. There is a lot of discussion on this to check whether it is a realistic approach or not as most of them are saying that it is quite good for new features every six months and there are lots of people complaining that it is quite difficult to adopt a JDK.

2) Garbage-Collector Interface (JEP 304) :

This is another significant and useful Java 10 features which enhances the code isolation of various garbage collectors and unveils a clean interface for garbage collectors. This implies that it is simple for excluding a GC from a JDK construction.

Read More :  Important 10 APIs And libraries That Java Developer Must Know
3) Parallel Full GC for G1 (JEP 307) :

One more significant feature which enhances G1 latencies worst-case by making a complete GC parallel. If you get to know about Java 9 release then G1 was made the default GC for JVM which was made to avoid complete GC but when the collections which are concurrent will have a memory which is good enough to fall back for creating a problem.

4) Alternative Memory Devices with heap allocation (JEP 316) :

A simple cool feature for enabling the HotSpot VM for allocating the Java object heap on a different memory device as mentioned by the user. For instance, this feature makes it feasible for assigning lesser priority processes for using NV-DIMM memory and rather allocate with greater priority in a multi-JVM environment.

5) JDK Forest is consolidated into a Single Repository (JEP 296) :

Housekeeping is the new Java 10 feature over here. It will gather various repositories of the JDK forest within a single repository.

6) Root Certificates (JEP 319) :

There is one more significant change that Java 10 is about to bring. If you are aware of JDK 10 creation with the close combination of Open JDK and is quite evident from his feature. A default set is offered for a root Certification Authority that makes Open JDK construction for lots of appealing developers. It also aims to decrease the difference between Oracle JDK and Open JDK construction.

7) Java Based JIT Compiler (JEP 317) :

This is one more significant feature for enabling Java-based JIT compiler for using an experimental JIT compiler on the Linux/x 64 platform.

8) Thread-Local Handshakes (JEP 312) :

For enhanced VM performance, Java 10 feature provides the groundwork for making it feasible for working out a callback on application threads where there is no performance of a global VM savepoint. There are various enhancements done for this feature of JEP 312 with few barriers for removing the JVM by only stopping isolated threads for revoking biases.

9) Get away from the native-header Generation Tool (JEP 313) :

This is one more Java 10 feature that targets the housekeeping and it will throw away the java tool from the JDK having an isolated for generating header files for going through javac.

Important 10 APIs And libraries That Java Developer Must Know

Let us see some third-party library developers in Java that can be used by the application of useful tasks. For using these libraries, Java developer must be aware of it and this is the main thing this blog explains.

1) Logging libraries

In every project, there is a need for logging libraries and they are quite common. They are quite significant from the server-side application as the logs are kept where it is visible for you to see what is actually present in your application. Although JDK shifts with its own library which is logging there are lots of better alternatives that are actually available eg: SLF4j, Log4j, and LogBack.

2) JSON parsing libraries

In the current world of web services and internet of things (IoT), JSON has become the go-to protocol for carrying information from client to server. The XML has been changed as the most wanted way for transferring information in a platform-independent way. There is no JSON library present in a JDK and yet luckily there are lots of good third-party libraries which permits you to both create and parse JSON messages.

Do You Know What Is JSON And Why It Is Used?

3) Unit testing libraries

The single most significant thing is unit testing which isolates and average developer from a good developer. For not writing unit tests, programmers often are given excuses but the most common excuse for ignoring unit testing is the experience and knowledge that is to be left for famous unit testing library eg: PowerMock, Junit, and Mockito.

4) General Purpose Libraries

If you are a Java developer you will definitely have a good time with very good general purpose and a third-party library in a Java developer eg: Apache Commons and Google Guava. In my projects, these libraries are present and they reduce lots of tasks.

5) Http Libraries

The lack of support for HTTP is the only thing which is not apt for JDK. With the help of using classes in java.net package, it is not quite simple and seamless by using open source, third-party libraries similar to HttpCore and Apache HttpClient.

The assistance of HTTP 2.0 is brought by the JDK9 and better assistance for HTTP with famous HTTP client libraries eg: HttpCore and HttpClient.

Best Java Libraries For Developers

6) XML parsing libraries

You can find lots of XML parsing libraries that are present eg: JAXB, Xerces, JAXP, Dom4j, Xstream etc. Xerces2 is the future generation of high performance and fully compliant XML parsers. The Xerces Native Interface (XNI) is unveiled by the latest version of Xerces and a complete framework for constructing parser components and configurations that is quite modular and simple to program.

7) Excel reading libraries

With the Microsoft Office, the real world application has to interact and you need to trust it or not in some form or the other. There are lots of application requirements for offering functionality to export data in Excel and if you are willing to do the same from your Java application by requiring Apache POI API.

8) Bytecode Libraries

For generating the code or interacting with bytecodes if you are writing framework or libraries then there is a need for bytecode library. They permit you to read and change the bytecode produced by an application. In Java, there are famous bytecode libraries like javassist and Cglib Nodep.

9) Database connection pool libraries

From Java application, if you are interacting with the database but not using database connection pool libraries then you are not having something. It takes time to create connections during runtime and make the request processing slower and it advises the DB connection library usage.

10) Messaging libraries

Messaging is the same as logging and database connection which is the common feature for most of the real-world Java application. JMS is offered by Java, but that has no portion linked to JDK and you need to have ideal jsm.jar.

Best And Highest Paying Programming Languages

On a daily basis, lots of unsatisfied professionals who are employees, students and jobless or underemployed workers think of programming as career choice which is apt. You will get to see software engineering job as the most paid jobs which are well represented and it mostly looks like lots of other jobs that need coding abilities.

It is interesting to note that the highest ranked positions are none other than the programming roles that do not need an advanced degree or few of licensure. This can be mixed with the fact that there is a good number of free learning material and course ware that is needed for aspiring developers and there is a good clarity of the appeal.

Their earning potential has been enhanced for those looking substantially without thinking about the cost of a legal degree or medical where coding is another unique option.

The (big) data

1) Stack Overflow

The Stack Overflow Developer Survey is a large volume of data in the year 2017 shows hat 64000 developers all over the world have been offered with a good amount of pay in the United States as:

1. Scala

2. Go

3. Objective-C

4. Coffee Script

5. Perl

There are top five languages globally like Rust, Closure, Elixir, F#, and Go in that order. Ahead of languages, stack overflow also had tools and technologies in 2016. It is noteworthy to mention that Cassandra, Apache Spark, and Adopt were in top five and one JavaScript library linked with Closure, Go and Perl. For checking the results there will not be much of a stretch for doing this point for achievement of big data.

2) Gooroo

Data analyzes and compilation is done by Gooroo for 500,000 job ads every months and it leads to consistency of Stack Overflow. The current data is the basis for its language rankings:

1) Scala

2) Clojure

3) Ruby

4) Bash

5) Python

The top of the list is done by Scala and Clojure and Gooroo does not have data on F#. Here the main odd man is Bash and as we cannot see Bash programmer as a job title.

If there are other tools includes included like the big data and JavaScript with Spark Cassandra, Node, Hadoop and Backbone that makes the top ten.

3) Indeed.com

A wealth of salary data is present in the Indeed with a page dedicated for users to search and compare salaries relying on nearly 1 million job ads, employees, and users over a one-year period. With the help of a subset of the most ranking languages from the Stack Overflow data and Gooroo here are top five:

1. Bash

2. Scala

3. Java

4. Go

5. Ruby

Bash stepped in more than 15000 dollars above Scala for an average annual salary which is larger in difference when compared to the space among the others in top five.

4) What to note about best-paying languages

Scala is considered as a language with good salary package with respect to the data with big data ecosystem of tools offering a good amount of paycheck as a field of interest. This is true as anecdotally it is considered that Scala is a good choice for using the listed big data tools.

Go and Clojure each ranked in the top five in two of the three datasets would coincide with what we actually expect.

Similar to Scala, both are actually young languages and is famous among smaller circles but is not that common and is basically used for industrial strength tasks inside the organization that depend completely on engineering expertise.

3 Best JVM Languages That Every Java Developer Must Know

If you want to learn Java programming for enhancing your knowledge and skill but you are not aware which programming language to select then you are welcomed over here to read this blog. There are three JVM languages that are best suited for Java programmers in 2018. It is definitely good to be a Polyglot developer and they are often valued high on interviews. It also enhances your thinking.

It also enhances your thinking as different programming languages have various features which make few things very easy.

You will get to know the experience and knowledge of comparing cons and pros of two programming languages, which is needed to write a better code.

Most of the language that is suggested by Java developers is JVM as they are easy to know about Java programmers. In some way or the other, there is a link related to Java and this is the reason behind the in-depth knowledge of the mind of any Java developer.

There are three programming language Java developer you need to know in 2018. It is very difficult to learn the languages therefore only three languages are mentioned:

1. Scala :

There has been a long time Scala has been around and when it arrived at first it was touted as the wonderful language to replace Java. This does not happen mostly after few functional programming features enhanced in Java 8 for instance stream and lambdas but Scala is still the language for most the Java developers.

In the past two years, Scala has enhanced lots of companies and startups for using the Sony, Uber, Autodesk, Amazon, etc which makes it the most wanted skill.

There are famous Scala frameworks like Spark, Play, Akka is also assisting companies for adopting Scala for web development and Big Data solutions no surprise that Scala developers are paid more than 120K USD on an average.

2. Kotlin :

In 2011, Kotlin was unveiled by JetBrains but no any programmers are able to pay attention till Google has unveiled it as the main language for Android Development on 2017 Google IO.

Similar to Groovy and Scala, Kotlin runs on the JVM platform and is later compiled to Java bytecode.

So if you are willing to learn Android development and want to make your app safe from NullPointerException and want to make your function with purity write few higher order function stuff or few functional programming stuff that you need to learn Kotlin in 2018.

3. Groovy :

The Groovy landscape in 2017 has been explored and from that experience, I can say that most of the Java developer must learn Groovy. Java programming is really complimented by it with its concise syntax and power programming features like collection literals, multi-line strings, def to define anything.

The lines of code will be reduced if you start learning Groovy when compared to Java. Spock framework is specification and descriptive based unit testing framework which is simpler and extends what Junit actually offers.

Significant Things You Need To Know About Java 9

During the month of September 2017, the recent version of Java has been announced by Java. It was unveiled after three years from the release of Java 8, by putting a wonderful Java that lies in the hands of developers.

In the release cycle for Java, Java 9 is a turning point. Let us see in this post we will get to know about new developer features in Java 9. Let us check from the point of view of operation there are enhancements and changes for security and performance.

1) Modularity

Let us check with the most significant feature of Java 9, the Java Platform Module System. With Java there is the biggest all-time problem that is running in library. On a big platform, 20 years of development takes its toll. There are lots of classes which gets held up similar to you expecting them in a big code base. Apart from this there is no point to encapsulate implementations of private classes in the JDK. External libraries proliferation are led by relying on the inner details which destroyed the Java platform evolution. Such dependencies are en-quired by the module system during execution and compilation.

Java 9 Features

2) Productivity

In addition to the module system, Java 9 has small features that improve developer productivity. For example, collection factory methods allow you to create immutable collections with predefined elements in a single statement. No more annoying workarounds needed to create small, predefined collections.

Java 9 and Jigsaw Modular System

3) Performance

A new version of Java is run often by getting performance enhancement and you cannot change the code. There is no exception in Java 9. An illustration of enhancement is the Compact Strings feature. There is no string that is exhibited with ASCII character set that is saved with a particular byte per character.

4)Security

The development features productivity are ahead from the only point of view to adopt Java 9. Lots of features are acquired by the platform which improves the security. In Java 9 there are lots of security enhancements for securing the networks. For securing HTTPS connections, the latest versions of TLS are now assisted. Apart from that stapling of certificates are assisted. There is no more security improvement with the filter incoming ability for serialization of data.

The curse of Java’s presence is none other than serialization which leads to lots security exploitation in the recent years. You can consider a blacklist or whitelist for filtering incoming serialization data streams by reducing the attack surface of Java serialization.

Accepting Java 8 Features in the Threshold of Java 9

5) Release Cycle

Until now we have discussed the Java 9 features. But you can find one more reason why Java ( is a significant release: The end of the era is marked by feature drove Java versions.

Conclusion

Java is made agiler than before because of these strategies. The significant features are split into progressive steps and offered every 6 months. Every time after their completion, the features are transferred and if one version is not available there is always one more version within 6 months.
