Java and JVM

Java and its vital enterprise JVM (Java Virtual Machine) are having various kinds of field to step in even after 18 years of old they are still young today in the market.

JVM is similar to C language and it has also provided multiple platforms for interfaces it also has strict feature, giving benefits in locality by improving linkage between memory and processors. It gives pros in the area of footprint and provides object with light weight. It is said that the byte code of Java 7 has been retaliation for the JVM.http://crbtech.in/Java-Training/images/java%2025.bmp

It has been expected that capability of struct to be added to the JVM at some point. Scala , A JVM language has welcomed the change called the foot print of struct so it is very much mind blowing.

It enables isolation and Google Android’s fails safe capability for Java and mobile banking. There was some impact observed and it was contained and there was not optimism about the capability as it will make it over to the JVM, citing policy and Java politics.

Java language and runtime are desirable by the Java Autonomous systems. It is felt that Lambda would be nearer and observed under parallelism. There is no need for explicit expression as it will be automated in terms of figuring it out.

It is also anticipated in terms of performance for Java Virtual Machine. False sharing leads to lack of memory. This is not a problem but these things are to be learnt and solved by the Java developers.

CRB TECH is the best institute which ranks in 12th position in India and we provide you training and guaranteed placement including as a professional in JAVA development.

Go for GO than Going for Java

Although Java has earned the name of everything in the recent years, Google’s go language is much fascinating and easy to use for most of the developers.

There are many benefits in using GO as the programming langue in terms packaging, modularity and concurrency by a developer in who uses GO as a platform. It would be a better choice for solving the issues like performance and modularityhttp://crbtech.in/Java-Training/images/go%20java.bmp

Detailed Study

But there are some critics as well for the Go language like it is very antique and it is not up to the mark for the modern language. It is said that it is software for building system level. Other languages having add-on frame works and other than that one can use GO as a standard language.

There are many built in capabilities in GO for maintaining the concurrency unlike Java. It is also easy for returning multiple values.

The closures and maps are also provided by GO to be associated with the key. The construct of Slice on Go is also praised. An array is integrated with slice to provide more sequence of data. Slices are used for array programming in GO.

Defer keyword offers semi automatic resource management. There is also availability of functional priority to decide or to choose the functions to run after which function.

It can be concluded that you can go for choosing GO when compared to Java in terms of modularity and performance and the declaration of package is not automatic it should be explicitly done.

JAVA

There is a question about the slipping position about the Java and C++ irrespective of its skill status.

But both C++ and Java are always evergreen since 2001. Although they are old in age the demand for both of them is really outstanding. And according to the ranking research of programming language Java has got second rank and C++ has got fourth rank.

It is believed that biological and statistical programming would replace JAVA and C++. But still there is a huge demand for Java as it ranks second.

For the post of developers there are millions of vacancies in many websites for JAVA and C++. But when compared to C++, Java is expected to maintain its reputation.http://crbtech.in/Java-Training/images/java%2024(3).bmp

And in C++ it has improved from C in terms of scaling and from C++ to other languages proves its lack.

It requires high level of understanding when compared to other languages and the ownership of C++ is costly than JAVA which has FOSS.

And in the recent rankings Java was in the same second rank where as C++ shifted to fifth rank and there was a shoot up in shares for JAVA.

And new software launched by APPLE called as SWIFT was introduced but ranked as 23rd and now it whipped itself to 18th rank. After frequent shifts in the ranking as the name says it can swiftly come in the top ten if apple maintains its position.

Java Secured

Since the last 15 years Java is ruling the write for enterprise applications. There is no wonder in this because there are many control access to sensitive data and this is the reason for most of the hackers as a target. There are awkward mitigation methods in the present and their presence is falsely certified. Of course there are new methods to imbibe the security structure inside JAVA and it can also avoid long standing problems inside Java Virtual Machine.

It might not be a straight forward task to provide securities for the Java apps in the Java world and there are thousands of lines of code imported from the third-party code libraries by the Java Programmers on a regular basis. The Common generic tasks performed as used by the imported code and XML processing, logging are also similar facts. On the contrary the sad part is the open source software is high in risk due to hackers. Imported code backdoor can have frequent risks into in house code. Enterprises are ignorant of risk but they are well known and elegant for the hackers.http://crbtech.in/Java-Training/images/java%2024(3).bmp

Using SQL injection attacks and other exploits if the flawed code is present then attackers can very well pierce the security. For reducing the risk they can use static analysis tools and developer training as well yes but they cannot stand for the security of the application once it steps into production. One that doesn’t require the interference of Java is a better approach for security.

Java World

The following are the points to be noted down for Java development:

    1. Java is universally acceptor. Before Oracle rising to power in the Java platform Sun Microsystems was in the lead, and under the General Public License JDK code was published in the year 2007 and external fillers gradually filled the remaining few missing pieces.
    2. Open JDK: It is a community which stands for togetherness and alliances. The primary implementation of the Java SE platform is held in alliance with the Open JDK for the java community. The code can be built and hacked by the community members of the Java and then they go on fixing a bug or improvise on the existing component. Until the now focus was on JDK8 and now they are shifting the focus to JDK 9.

http://crbtech.in/Java-Training/images/java%2024(2).bmp

  1. The participation of the community is a process: The 15th year milestone was celebrated by Java Community this year and it is said that it is an open, containing active members and inactive members in the organization for the development and acceptance of Java technical specifications. For an alliance process around Java Sun introduced JCP in 1998.Java Specification Request is open to anyone for editing and updating existing or new technology to begin with one can become a member of JCP and then can move ahead with an expert in JSR.
  2. 4.The drive development support by Java: passionate technology and community leaders are the amazing the java champions and they are chosen by the community and they are taken into the project sponsored by oracle. For the growth of the oracle there are many critics sent by Java champions.

Java and JavaScript for development

It is said to integrate the java and JavaScript application for the development of web. Angular.js JavaScript framework, the Spring Java framework, and the Yeoman scaffolding tool are the open source offering maximum of pros as a group of technologies. For the purpose of building business applications and games this technology is used for making a difference.

The angular.js and JavaScript are about to be integrated for the front end and Java at the back end. And the kind of work they do is unpredictable and mind blowing. Spring MVC REST, the Maven build tool for Java, and Spring Data JPA, all on the server side are the other advantages of this technology.http://crbtech.in/Java-Training/images/java%2024(4).bmp

For running JavaScript and CSS runner Grunt package JavaScript runner is used. Dependency injection from other framework is offered by Angular.js framework. Spring is also considered as an added advantage for development of the web.http://crbtech.in/Java-Training/images/java%2024(5).bmp

Such applications can also be imbibed in mobile phones and smart phones and many other devices like tablets. Even java 7 or 8 applications can be built. Even the SQL database can be used with hipster software.

Java supporting tools

There are some modern developers tools for assisting you in filtering the bugs before they start their havoc and these tools are: Raygun, Stack Hunter, Sentry, Takipi and Airbrake

If at all you look at technology the java ecosystem is growing exponentially and there is a demand for high performance as well and therefore it bags a new style or stock of modern development tools. It is a rapid based environment and it has innovative new technology and the look out on level traditional methods sustains itself.

Raygun

It is an error management tool that is mind space and it keeps tracks of all the indefinite or undetermined coming out of the apps of java.  Mobile and web programming languages like java and scala , .NET, Python, PHP, and JavaScript are supported. It is also possible to send errors to Raygun through REST API as well.http://crbtech.in/Java-Training/images/java%2024(1).bmp

Sentry

An open source and web based solution it makes a difference for logging and web based platform as well. It acts like a watchman for the software to look for the source of the error and it not only relies on the user input it also relies on its own self. Ruby Java, .Net, Python are all supported languages.

Takipi

It is far much better than other tools in terms of tracing. The motto for engineering such tool is very simple that is specifying developers for the reason of time of taking place and why did it take place. If at all any exception is caught by the takipi then it shows the variable state of the machines.

 Airbrake

The next kind of tool which makes the difference in error tracing is Air brake whose motto is no more log files. Dash board with error details and application specific view helps in rectifying the error. Swift, python, PHP, Ruby, Java .

StackHunter

For tracking java exceptions it provides self hosted tools. The difference is the change of scenery from last hosted tool. It also helps the developers in providing them exception if at all it has been caught and thus it makes a difference

CRB TECH is the best institute which ranks in 12th position in India and we provide you training and guaranteed placement including as a professional in java development.

JavaScript vs. Ruby on Rails

It is almost more than a decade for ruby on rails and its adventure in today’s market but it is losing its importance and the spot light is over taken by JavaScript.

Know more

For the funny and creative visualization o f the web development ruby on rails was introduced and had been used for the past ten years. The prime focus a decade ago was on fun and entertainment. The difference between PHP and JAV was in terms of performance either slow or clean or either quick and dirty. And as expected there was place for moderation quick and cleanhttp://crbtech.in/Java-Training/images/java%208.bmp

The moment it was launched in 2004 it was applied for many websites like twitter to many other shopping websites. There are a wide range of rail developers.

Java and JavaScript

Although the name sounds similar both java and JavaScript are two different programming languages. Android mobile platform and the enterprise application development are linked with java. For web development JavaScript is the common language used.

There is a possibility of developers switching to JavaScript may be out of interest in both the language at the same time. There is a talk about java international meet as well.http://crbtech.in/Java-Training/images/Java%204.bmp

Java and JavaScript- a tug of war

The motto is to find the start of java in both the languages is and that is the reason compare and contrasts take place. There are also scopes for some content writers who work for java development and for Java EX but prefer to work for JavaScript as well and vice versa.

Plain java script is compiled by typescript a super superscript of java. Those who write JavaScript on the client will be cover this.

There are some open source frameworks about to be created for combining both java and JavaScript together in a single software

And there is no surprise for oracle’s interest towards JavaScript. The right audience is caused as the forum by the JAVA ONE.

There are quite developers who are spending more time with JavaScript, including Java, .Net, and HTML developers

Java Security

Cyber criminals always keep java as their target for attacking and the usage of the security. Let us see about the latest improvement in java.

For the last 12 to 15 years enterprise was written in java. The reason for security is sensitive data and that’s why it is the target for most the criminals. The innovation is the installment of new security in the java virtual machine.

Because of the import of java codes from anonymous person there is no concrete security. There are many works performed by the imported code like some XML processing or databases or even logging. Open source codes are free to download but the unfortunately you can feel the insecurity out of it due to hackers. The risk involved is there always and everywhere. Most of the common public or entrepreneurs are ignorant of it but hackers who are notorious are always elegant of it.http://crbtech.in/Java-Training/images/Java%203.bmp

Attackers always use SQL injection data for attack. Sophisticated training of the developer and static system will not be aware of the risk induced after the stage of production.
