Freeware products can be used free of charge for both personal and professional (commercial use). Or, you may use the Jar utility in the JDK's bin/ directory: jar xvf src.zip.ДЄlso Available: Download Java Development Kit for MacДЇreeware programs can be downloaded used free of charge and without any time limitations. To extract these files, use any common zip utility. These files do not include platform-specific implementation code and cannot be used to rebuild the class libraries. This source code is provided for informational purposes only, to help developers learn and use the Java programming language.

It consists of a Java Virtual Machine and all of the class libraries present in the production environment, as well as additional libraries only useful to developers, and such as the internationalization libraries and the IDL libraries. The JDK 64-bit also comes with a complete Java Runtime Environment, usually called a private runtime. This tool also helps manage JAR files, javadoc - the documentation generator, which automatically generates documentation from source code comments, jdb - the debugger, jps - the process status tool, which displays process information for current Java processes, javap - the class file disassembler, and so many other components. JDK has as its primary components a collection of programming tools, including javac, jar, and the archiver, which packages related class libraries into a single JAR file. Java Development Kit 64-bit (also known as JDK) contains the software and tools that you need to compile, debug, and run applets and applications that you've written using the Java programming language.
