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 12?
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 12`
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 You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.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:
