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.

Java SE 7 API Documentation

See Java Platform, Standard Edition 7 API Specification for API documentation for intermediate snapshot releases.

What's New in Java SE Documentation

Java SE documentation is regularly updated to provide developers with in-depth information about new features in the Java platform. Some recent updates include:

NIO 2.0

The java.nio.file package and its related package, java.nio.file.attribute, provide comprehensive support for file I/O and for accessing the file system.

See File I/O (featuring NIO 2.0) in the Java Tutorials.

Sockets Direct Protocol

Sockets Direct Protocol (SDP) is a wire protocol developed to support stream connections over InfiniBand fabric.

For more information, see Understanding the Sockets Direct Protocol a trail in the Java Tutorials.

Java Rich Internet Applications Development and Deployment

Rich Internet Applications can be developed and deployed as applets or Java Web Start applications. The next generation Java Plug-in introduced in Java SE 6 update 10 provides powerful capabilities to applets.

Language Enhancements

Java SE 7 introduces the following language enhancements:

JDBC 4.1

JDBC 4.1 introduces the following features:

  • The ability to use a try-with-resources statement to automatically close resources of type Connection, ResultSet, and Statement
  • RowSet 1.1: The introduction of the RowSetFactory interface and the RowSetProvider class, which enable you to create all types of row sets supported by your JDBC driver.
Java Virtual Machine Enhancements

Java SE 7 introduces a new JVM instruction that simplifies the implementation of dynamically typed programming languages on the JVM. See Java Virtual Machine Support for Non-Java Languages for more information.
