Question

How can you change the default version of Java on a mac?

Answer 1

Follow these steps to change the default version of Java on mac:

• Open the Terminal

• Confirm that you have JDK by typing “which java”. It should show something like /usr/bin/java.

• Check you have the needed version of Java, by typing “java -version”.

  •         JAVA_HOME is typically the full path of the directory that includes a sub-directory named bin which in turn holds the java.

  •         For Mac OSX – it's /Library/Java/Home

• Set JAVA_HOME doing this command in Terminal: export JAVA_HOME=/Library/Java/Home

• echo $JAVA_HOME on Terminal to validate the path

•  You should now be able to run your application
