    With the Java optional package or Oracle JDK installed,
    adding one of the following lines to your ~/.bash_profile file will set the environment variable accordingly.

    export JAVA_HOME="$(/usr/libexec/java_home -v 1.6)"
or
export JAVA_HOME="$(/usr/libexec/java_home -v 1.7)"
or
export JAVA_HOME="$(/usr/libexec/java_home -v 1.8)"
or simply
export JAVA_HOME="$(/usr/libexec/java_home)"

    Note: If you installed openjdk on mac using brew, run sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk for the above to work

    Update: added -v flag based on Jilles van Gurp response.
