Java Jdk Mac Os

System Requirements for Installing the JDK on macOS

The following are the system requirements for installing the JDK on macOS:

  • Any Intel-based computer running macOS.

  • Administrator privileges.

    You cannot install Java for a single user. Installing the JDK on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK on macOS.

Determining the Default JDK Version on macOS

When starting a Java application through the command line, the system uses the default JDK.

Line
There can be multiple JDKs installed on the macOS system.
Jdk

You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 11 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 11. For example:

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

Download Jdk 8

$ /usr/libexec/java_home -v 11 --exec javac -version

Installing the JDK on macOS

  1. Download the JDK .dmg file, jdk-11.interim.update.patch-macosx-x64.dmg.

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

  2. From either the browser Downloads window or from the file browser, double-click the .dmg file to start it.
    A Finder window appears that contains an icon of an open box and the name of the .pkg file.
  3. Double-click the JDK 11.pkg icon to start the installation application.
    The installation application displays the Introduction window.
  4. Click Continue.
  5. Click Install.
    A window appears that displays the message: Installer is trying to install new software. Enter your password to allow this.
  6. Enter the Administrator user name and password and click Install Software.
    The software is installed and a confirmation window is displayed.
After the software is installed, you can delete the .dmg file if you want to save disk space.

Uninstalling the JDK on macOS

You must have Administrator privileges.

Note:

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 that you perform an update of the OS.

  1. Go to /Library/Java/JavaVirtualMachines.
  2. Remove the directory whose name matches the following format by executing the rm command as a root user or by using the sudo tool:
    /Library/Java/JavaVirtualMachines/jdk-interim.update.patch.jdk

    For example, to uninstall 11 Interim 0 Update 0 Patch 0:

    $ rm -rf jdk-11.jdk

Installation FAQ on macOS Platform

This topic provides answers for the following frequently asked questions about installing JDK on macOS computers.

1. How do I find out which version of Java is the system default?

When you run a Java application from the command line, it uses the default JDK. If you do not develop Java applications, then you do not need to worry about this. See Determining the Default JDK Version on macOS.

2. How do I uninstall Java?

See Uninstalling the JDK on macOS.

3. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 11?

If you want to continue to develop with Java 6 using command-line, then you can modify the startup script for your favorite command environment. For bash, use this:

$ export JAVA_HOME=`/usr/libexec/java_home -v 11`

Java Command Line Examples

Some applications use /usr/bin/java to call Java. After installing Java for macOS 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java-related command-line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.

4. Can I restore Apple Java after uninstalling Oracle Java?

Go back to Apple Java using the following instructions:

  1. Uninstall Oracle Java by deleting the plug-in file. From a command-line, enter:

    $ sudo rm -rf '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin'

  2. Create a symlink using the following command, entered on a single line:

    $ sudo ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/JavaAppletPlugin.plugin '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin'

5. What happened to the Java Preferences app in Application Utilities? Microsoft outlook for macbook pro free download.

The Java Preferences app was part of the Apple Java installation and is not used by Oracle Java. Therefore, macOS releases from Apple that do not include Apple Java will not include Java Preferences.

Install Java 8 Jdk

You can find Java version on Mac without running a Java applet in your web browser. Fortunately, there are a variety of methods to find the Java version on Mac. Below is a description of some of those methods. Also see Java Support in Safari 12.

Using Command Line in Terminal

Terminal is a program included with macOS that provides command line access to the operating system. Terminal is located under Applications folder -> Utilities folder. To find the Java version using command line, launch the Terminal application. Type or copy/paste the following line into the Terminal window:

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version

The Java version will display as output in the Terminal window, and will look similar to the output below:

java version '1.8.0_40'
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

In this case, Java 8 Update 40 is the Java version installed on this Mac.

Using the Java Control Panel

You may find Java version on Mac using the Java Control Panel instead. For information about locating the Java Control Panel, please see the Where is the Mac Java Control Panel located article. Once you have launched the Java Control Panel, click the General tab.

In the section entitled About, click the About… button. A new About Java window will launch. Java version information will display within the window.

In this case, Java 8 Update 40 is the Java version installed on this Mac.

Using the Online Test Java Page

You may also test your Java online to determine which version of Java is installed on your Mac. To test Java on your Mac, visit the Test Java page provided by Oracle on its Java.comweb site. This utility will not only check your current Java installation, but will also remove old Java versions from your computer that may pose a security threat to your system. If your Java is working correctly, and no out-of-date Java versions are found, you will see the following notification accompanied by information about your Java installation and your computer:

As it states in the Verified Java Version web page, Java 8 Update 40 is installed on this Mac. If your Java is not working properly, the Test Java page displays additional configuration options that you may need to check, as well as download and installation instructions if needed.
