JDK 7 Preview Release available
Discussion started by TechFundu Developer , on 30 July 05:54 PM
Java Development Kit 7 (JDK 7) is the next major release of the Java SE platform. JDK 7 is a highly collaborative effort between Sun and volunteers from the Java developer community.
Key Features
JDK 7 introduces several key features to improve performance, usability, and security of the Java platform.
Modularization:
A large-scale effort to refactor, or break up, the Java SE platform into smaller, separate, interdependent modules. Individual modules can then be downloaded as required by the Java virtual machine and/or Java applications. This effectively shrinks the size of the runtime on the user's machine.
One benefit of modularization is that the platform is a smaller download, potentially improving start-up performance. Having a smaller memory footprint also enables significant performance improvements, especially for desktop applications. A smaller platform also means it can now fit on devices with less memory.
Multi-Language Support:
Improves compatibility between Java and various dynamic languages, such as Ruby and Python, by providing better-than-native implementations of these languages on top of the Java Runtime Environment (JRE).
Performance:
A technique for compressing 64-bit pointers to fit into 32 bits, which decreases memory and memory-bandwidth consumption and thereby improves performance (VM-level feature)
The new Garbage First (G1) Garbage Collector is a low pause, server-style garbage collector that will eventually replace the Concurrent Mark-Sweep (CMS) garbage collector. G1's primary advantage over CMS are incremental compaction, better predictability, and ease of use
Developer Productivity:
JDK 7 will also include several features to enhance developer productivity. One of Sun's goals is to make JDK 7, and other versions of the JDK, as developer-friendly as possible.
