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

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 14?

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 14`

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.
