 The JDK is a development environment for building applications, applets, and components using the Java programming language.
The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the JavaTM platform.
Contents of the JDKTM:
- Development Tools
(In the bin/ subdirectory) Tools and utilities that will help you develop, execute, debug, and document programs written in the JavaTM programming language. For further information, see the tool documentation.
- Runtime Environment
(In the jre/ subdirectory) An implementation of the Java Runtime Environment (JRETM) for use by the JDK. The JRE includes a JavaTM Virtual Machine (JVMTM), class libraries, and other files that support the execution of programs written in the JavaTM programming language.
- Additional Libraries
(In the lib/ subdirectory) Additional class libraries and support files required by the development tools.
- Demo Applets and Applications
(In the demo/ subdirectory) Examples, with source code, of programming for the JavaTM platform. These include examples that use Swing and other JavaTM Foundation Classes, and the JavaTM Platform Debugger Architecture.
- Sample Code
(In the sample subdirectory) Samples, with source code, of programming for certain Java API's.
- C header Files
(In the include/ subdirectory) Header files that support native-code programming using the Java Native Interface, the JVMTM Tool Interface, and other functionality of the JavaTM platform.
- Source Code
(In src.zip) JavaTM programming language source files for all classes that make up the Java core API (that is, sources files for the java.*, javax.* and some org.* packages, but not for com.sun.* packages). This source code is provided for informational purposes only, to help developers learn and use the JavaTM programming language. These files do not include platform-specific implementation code and cannot be used to rebuild the class libraries. To extract these file, use any common zip utility. Or, you may use the Jar utility in the JDK's bin/ directory:
jar xvf src.zip
