What Java 7 Brings In For Developers?

Java 7 brings a multitude of improvements for developers from its earlier versions

. After a long wait this release does not come up with all the expectations for Java developers. But it does offer various enticing capabilities ranging from programming improvements that can boost Java application development as well as multicore systems too. It is known officially as Java Platform Standard Edition 7, Java SE 7 and it is the first big release in more than five years that we could notice in Java. Java SE 7 is chosen for developing quick and dynamic Java solutions as it improves running of dynamic languages, file systems and programming.

James Gosling left Oracle in the year 2010 and is the founder of Java but has not involved much in developing this edition of Java SE 7. As per his views this upgrade is critical as Oracle has finally got it done. This edition is not important for particular feature but for the fact that Oracle was able to bust the Java community process and is the reason for long delay. As per the talks by an ICD analyst the main thing for Java SE is that it shipped. It had to overcome the inertia of five years without a release. So it is the politics that runs in Java community delayed many new features in Java 7 editions.

It is quite sad but true that even after a long wait & efforts of five years, Java SE 7 has not bought the developers as per its original planning. The coming edition that is due in the year of 2012 of Java JDK 8 has got many features pushed from the original JDK 7. Thus we can see Java 7 as the first part of two releases, one is yet to come. Seeing it positively it is not a bad thing and quite a good effort by Oracle to release Java 7 and move to the 8th version.

The awaited and delayed capabilities that developers wish for their Java solutions are addition of Lambda expressions, or closures, to Java that is used for multicore programming, language and VM support for modular programming and a module system for the JDK. Still developers have bunch of useful new capabilities in Java 7 for their Java application development.

Key new capability: Support for dynamic languages

Java SE 7 brings a new feature and that is accommodating dynamic languages that are prominent on JVM lately, thanks to emergence of languages like Scala and JRuby. For example,

For example, with new InvokeDynamic capability you can support for implementing dynamically typed, object-oriented languages. This is because it is an efficient and flexible execution of method invocations that can be used if static type information is not present. This support for dynamic languages is the most important feature that Java SE 7 brings for you for your Java solutions. It also helps developers to expand the Java ecosystem.

Key new capability: Better multicore and parallelism support

Another key feature that Java 7 brings is an API which is multicore-ready from the Fork/Join framework. This feature allows developers to easily decompose problems into tasks for parallel execution across multiple processor cores. Clients can also opt for Java consulting services to solve any problems or to get more out of their existing solutions. There are many quality service providers who offer Java consulting services at competitive prices.
