System Requirements for Installing 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.

You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 13 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 13. For example:

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

$ /usr/libexec/java_home -v 13 --exec javac -version

Installing the JDK on macOS

1. Download the JDK .dmg file, jdk-13.interim.update.patch_osx-x64_bin.dmg.

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

Uninstalling the JDK 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 13?

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 13`

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 You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.
