Java SE 7 Documentation

Java SE 7 is the next major release of the Java SE platform and is currently available as an early access release. Java SE 7 documentation will be regularly updated as and when new features are added to the Java SE 7 platform. You can also expect to see changes in content for existing features.

The two principal products in the Java SE platform are: Java Development Kit (JDK) and Java SE Runtime Environment (JRE).

The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing applets and applications. The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language.

The following conceptual diagram illustrates all the component technologies in Java SE platform and how they fit together.
