Java Development Kit (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. 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. 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. The JDK also comes with a complete, usually called a private runtime.
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.

Contents of the JDK: 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. Runtime Environment (In the jre/ subdirectory) An implementation of the Java Runtime Environment (JRE) for use by the JDK. The JRE includes a Java Virtual Machine (JVM), class libraries, and other files that support the execution of programs written in the Java 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 Javaplatform. These include examples that use Swing and other Java Foundation Classes, and the Java 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 JVM Tool Interface, and other functionality of the Javaplatform. Source Code (In src.zip) Java 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 Java 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.
JDK 8
Also Available.
Go on the Oracle website - the thing you are looking for is x86, not x32. You can pick whichever version of Java you need.
The newest one is Java 7, but keep in mind that a lot of people are still using Java 6. I think it is an important skill (especially if you plan to do serious work with Java) to know how to maneuver in the Oracle website (and documentation) because you will be using it a lot. Try to avoid Google, and other mirror websites, it's always the safest to take things from the source.
JDK Installation for Microsoft Windows See for general information about installing JDK 7 and JRE 7. The following topics are covered:. See for information about supported platforms, operating systems, and browsers.
See for minimum processor, disk space, and memory requirements. Note:. The JDK and JRE have a version string that enables you to determine the version number. See for information about Java SE 7 version numbers. The JDK has the option of installing the public JRE. For more information about JRE installation, see.
If you have any difficulties, see the section at the end of this document or for your installation problem. For any text in this document that contains the following notation, you must substitute the appropriate update version number: For example, if you were downloading the JDK installer for 32-bit systems for update 1.7.001, the file name: jdk-7-windows-i586.exe would become jdk-7u1-windows-i586.exe. Similarly, if you were downloading the JDK installer for 64-bit systems for update 1.7.001, the file name jdk-7-windows-x64.exe would become jdk-7u1-windows-x64.exe. In this procedure, you will run the self-installing executable file to unpack and install the JDK. As part of the JDK, this installation includes an option to include the public Java Runtime Environment.
(The JDK also contains a private JRE for use only by its tools; see for more information.) Install the JDK by doing the following:. If you save the self-installing executable file to disk without running it from the download page at the web site, note that its byte size provided on the download page. After the download has completed, verify that you have downloaded the full, uncorrupted software file.
You must have administrative permissions in order to install the JDK on Microsoft Windows. The file jdk-7-windows-i586-i.exe is the JDK installer for 32-bit systems. The file jdk-7-windows-x64.exe is the JDK installer for 64-bit systems.
If you downloaded either file instead of running it directly from the web site, double-click the installer's icon. Then, follow the instructions the installer provides.
The installer may ask you to reboot your computer. When finished with the installation, you can delete the downloaded file to recover disk space. Note: Installers for JDK 7u6 and later install the JavaFX SDK and integrate it into the JDK installation directory. Installers for JDK 7u2 to 7u5 install the JDK first, then start the JavaFX SDK installer, which installs JavaFX SDK in the default directory C: Program Files Oracle JavaFX 2.0 SDK or C: Program Files (x86) Oracle JavaFX 2.0 SDK on 64-bit operating systems. If you want to install the JavaFX SDK (version 2.0.2) with JDK 7u1 or earlier, see for more information.
Starting with JDK 7u40 release, Java menu items are added to the Windows Start Menu to provide easy access to Java resources. During JDK install, a Java Development Kit folder is created in the Windows Start Menu, which contains the following items:. Reference Documentation: opens the Online API documentation web page. Java Mission Control: opens the Java Mission Control profiling and diagnostics tools suite. During JDK install and uninstall processes, the appropriate start menu items are updated to be associated with the latest JDK version on the system.
Note: Java Mission Control is a commercial feature available to users with a Java SE Advanced license. You can perform a silent, non-interactive, JDK installation by using the command-line arguments.
The Java Development Kit is a collection of tools that developers use to deploy applications written in Java. It's not for writing apps but rather for compiling, debugging, and deploying Java apps in a variety of applications and platforms, such as Windows and Android. We looked at JDK Version 8 for 32-bit Windows.
The latest update includes various bug and security fixes. Pros Toolset: Java Developer Kit offers a vast selection of 'goodies' including javac (compiler), jar (archiver), and jdb (debugger). Up to date: The JDK packs a lot for a free toolkit, but it's also updated regularly, experimental tools are sometimes available, and it works with other SDKs and tools.
Private runtime: The JDK includes a full private Java Runtime Environment consisting of a Java Virtual Machine and full set of libraries. Cons What could go wrong? The JDK helps you debug Java, but some users have encountered issues using it in certain platforms, such as Android. The good news is that copious troubleshooting resources are a search away. Don't say SDK: JDK is the preferred name for the Java SE Development Kit, since the Java EE SDK comes with or without the JDK.
It's a bit confusing, but at least you have options. Bottom Line It should be pretty obvious that the Java Development Kit isn't something the average Windows user needs (or wants, really). But the JDK is a powerful toolkit for Java programmers, and it's free.
