jdk1.6结构 目录讲解

This page provides an introductory overview of the JDK directories and the files they contain. Note that the file structure of the JRE is identical to that of the JDK's

jre

directory.

Development Files and Directories

This section describes the most important files and directories required to develop applications for the Java platform.
(Note that some of the directories that are not required include demos, Java source code, and C header files. These are mentioned in the Additional Files and Directories section.)

c:\jdk1.6.0Root directory of the JDK software installation.Contains copyright, license, and README files. Alsocontains src.zip, the archive of source code forthe Java platform.
c:\jdk1.6.0\binExecutable files for the development toolscontained in the Java Development Kit. The PATH environment variable should contain an entry for thisdirectory. For more information on the tools, see the JDK Tools.
c:\jdk1.6.0\libFiles used by the development tools. These include tools.jar, which contains non-core classes for support of the tools and utilities in the JDK. Also includes dt.jar, the DesignTime archive of BeanInfo files that tell interactive development environments (IDE's) how to display the Java components and how to let the developer customize them for an application.
c:\jdk1.6.0\jreRoot directory of the Java runtime environment used by the JDK development tools. The runtime environment is an implementation of the Java platform. This is the directory represented by the java.home system property.
c:\jdk1.6.0\jre\binExecutable files and DLLs for tools and libraries used by the Java platform. The executable files are identical to files in /jdk1.6.0/bin. The java launcher tool serves as an application launcher (and replaced the old jre tool that shipped with 1.1 versions of the JDK). This directory does not need to be in the PATH environment variable.
c:\jdk1.6.0\jre\bin\clientContains the DLL files used by the Java HotSpotTM Client Virtual Machine.
c:\jdk1.6.0\jre\bin\serverContains the DLL files used by the Java HotSpotTM Server Virtual Machine.
c:\jdk1.6.0\jre\libCode libraries, property settings, and resource files used by the Java runtime environment. For example:·rt.jar -- the bootstrap classes (the RunTime classes that comprise the Java platform's core API).·charsets.jar -- character conversion classes.Aside from the ext subdirectory (described below) there are several additional resource subdirectories not described here.
c:\jdk1.6.0\jre\lib\extDefault installation directory for Extensions to the Java platform.·localedata.jar -- locale data for java.text and java.util.
c:\jdk1.6.0\jre\lib\securityContains files used for security management. These include the security policy (java.policy) and security properties (java.security) files.
c:\jdk1.6.0\jre\lib\appletJar files containing support classes for applets can be placed in the lib/applet/ directory. This reduces startup time for large applets by allowing applet classes to be pre-loaded from the local file system by the applet class loader, providing the same protections as if they had been downloaded over the net.
c:\jdk1.6.0\jre\lib\fontsContains TrueType font files for use by the platform.

Additional Files and Directories

c:\jdk1.6.0\src.zip

Archive containing source code for the Java platform.

c:\jdk1.6.0\demo

Examples, with source code, that show you how to program for the Java platform.

c:\jdk1.6.0\demo\applets

Applets that can be used on a web page.

c:\jdk1.6.0\demo\jfc

Examples that use Java 2DTM and JFC\Swing functionality.

c:\jdk1.6.0\demo\jpda
