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?

3. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 12?
Java 6 Se Download Mac
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 You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.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?
Java Se 6 For Mac
Go back to Apple Java using the following instructions:
Uninstall Oracle Java by deleting the plug-in file. From a command-line, enter:
