In summary, if you are trying to figure out where JAVA_HOME is on your Mac OS X system, I hope this has been helpful. You might also be able to find some of these settings in the Mac OS X Control Panel, but I looked just now, and did not see them (though you can see Java's "temporary internet files" from that console). If you have XCode installed you can now find the JAVA_HOME directory with this command: I have no way of verifying this any more, but on Mac OS X 10.5, 10.6, and 10.7, I'm pretty sure this is where the JDK JAVA_HOME was located: Library/Internet\ Plug-Ins/ugin/Contents/Home/bin/java -version Older Mac OS X systems This is confirmed by this Oracle Java/JRE documentation page, which shows that you can demonstrate this by running this command in the Mac Terminal: Library/Internet Plug-Ins/ugin/Contents/Home If you've installed the Oracle JRE (as opposed to the JDK), JAVA_HOME for it appears to be located here instead: Of course that will vary by the JDK version you have installed.

The worlds most popular programming language is easy to set up and install on a Mac, and there are plenty of resources to. I use an adapted version of the switch jdk function that unsets the JAVA_HOME variable before it gets set to a new value. Learning Java is one of the smartest things you can do at the moment. I prefer aliases to set the correct java version for the $1 parameter. However it can be also any arbitrary string. The $1 parameter value shall be the java version to set. The AdoptOpenJDK repository offers a function you can use in ~/.bashrc or ~/.zshrc: You can specify the major version only: export JAVA_HOME=$(/usr/libexec/java_home -v "1.8") Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home You need to unset JAVA_HOME variable before you can set a new value for JAVA_HOME: $ unset JAVA_HOME

However, setting the JAVA_HOME variable does not work this way in macOS BigSur (version 11): $ export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_275` $ echo $JAVA_HOMEĬhanging the java version in macOS prior to version 11 would be: export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_275` The JAVA_HOME variable is set to java version 15 after executing the brew install commands above. Library/Java/JavaVirtualMachines/adoptopenjdk-15.jdk/Contents/Home
