“Java 7 is the release everybody has been waiting for quite a long time,” said Ben Evans of the London Java Community (LJC). Evans, who also is the LJC’s representative on the Java Standard Edition/Enterprise Edition (Java SE/EE) Executive Committee, added that Java 7 is “an enabler” that will give developers more options for building better Java applications.
- A new multicore-ready API that enables developers to more easily decompose problems into tasks that can then be executed in parallel across arbitrary numbers of processor cores. (JSR 166: Fork/Join Framework)
- Language changes to help increase developer productivity and simplify common programming tasks by reducing the amount of code needed, clarifying syntax and making code easier to read. (JSR 334: Project Coin)
- Expanded support for internationalization, including Unicode 6.0 support
- A comprehensive I/O interface for working with file systems that can access a wider array of file attributes and offer more information when errors occur. (JSR 203: NIO.2)
- New networking and security features.
- System and Process CPU monitoring.
Java 7 New Features
Java 7 gives the Java platform a significant facelift not just in performance benchmarks but also on bunch of new features. Below are the features, enhancements in detail:
Dynamic Language Performance Boost
The JVM was obviously designed for Java, and all the invocation modes are organised around Java semantics, however, low-level support and a stronger under girding for other language features has now been officially added to JVM.
API for Parallel Programming / Multicore programming
Java Development Kit (JDK) 7 also features a new API for parallel programming or building applications for multicore systems. The new Fork/Join Framework enables developers to break down problems into subtasks that can be executed in parallel across a number of processors.
New I/O optimized for different Filesystems
Java 7 adds a new I/O for working with different file systems, new networking and security features, and backward compatibility with other versions of the platform.
