This page describes how to install and uninstall JDK 8 for OS X computers.

  • The “Java Decompiler project” aims to develop tools in order to decompile and analyze Java 5 “byte code” and the later versions. JD-GUI is a standalone graphical utility that displays Java source codes of “.class” files.
  • The Java JDK ships with the jps command which lists all Java process ids. You can run this command like this: jps -l 70660 sun.tools.jps.Jps 70305. Note: In Linux and UNIX, you may have to run this command as sudo -u user jps -l, where 'user' is the username of the user that the Java process is running as.

System Requirements

Observe the following requirements:

  • Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

  • Administrator privileges.

Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.

JDK Installation Instructions

When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Depending on your processor, the downloaded file has one of the following names:

  • jdk-8uversion-macosx-amd64.dmg

  • jdk-8uversion-macosx-x64.dmg

Where version is 6 or later.

  1. Download the file.

    Before the file can be downloaded, you must accept the license agreement.

  2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

    A Finder window appears containing an icon of an open box and the name of the .pkg file.

  3. Double click the package icon to launch the Install app.

    The Install app displays the Introduction window.


    Note:

    In some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the Continue button.

  4. Click Continue.

    The Installation Type window appears.

  5. Click Install.

    A window appears that says 'Installer is trying to install new software. Type your password to allow this.'

  6. Enter the Administrator login and password and click Install Software.

    The software is installed and a confirmation window appears.

  7. Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.

  8. After the software is installed, delete the .dmg file if you want to save disk space.

Determining the Default Version of the JDK

If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.

There can be multiple JDKs installed on a system, as many as you wish.

When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:

To run a different version of Java, either specify the full path, or use the java_home tool:

For more information, see the java_home(1) man page.

Osx

Uninstalling the JDK

To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

For example, to uninstall 8u6:

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.

The “Java Decompiler project” aims to develop tools in order to decompile and analyze Java 5 “byte code” and the later versions.

JD-GUI is a standalone graphical utility that displays Java source codes of “.class” files. You can browse the reconstructed source code with the JD-GUI for instant access to methods and fields.

JD-Eclipse is a plug-in for the Eclipse platform. It allows you to display all the Java sources during your debugging process, even if you do not have them all.

JD-Core is a library that reconstructs Java source code from one or more “.class” files. JD-Core may be used to recover lost source code and explore the source of Java runtime libraries. New features of Java 5, such as annotations, generics or type “enum”, are supported. JD-GUI and JD-Eclipse include JD-Core library.

JD-Core, JD-GUI & JD-Eclipse are open source projects released under the GPLv3 License.

  • JD-Core and JD-GUI are written in Java.
  • JD-Core works with most current compilers including the following:
    • JDK 1.1.8, JDK 1.3.1, JDK 1.4.2, JDK 1.5.0, JDK 1.6.0, JDK 1.7.0, JDK 1.8.0, JDK 9.0.1, JDK 10.0.2
    • jrockit90_150_06
    • jikes-1.22
    • harmony-jdk-r533500
    • Eclipse Java Compiler v_677_R32x, 3.2.1 release
  • JD-GUI supports Drag and Drop.
  • JD-GUI supports CLASS, JAR, WAR, EAR, AAR, KAR, JMOD & ZIP files.
  • JD-GUI displays color coded Java source code.
  • JD-GUI allows you to browse the CLASS files and Java modules hierarchy.
  • JD-GUI lets you drag and drop LOG files, decompile CLASS files, and display the line of code that appears in Java stack traces.
