Recently we have started upgrade our java applications to start using Java 8.  Wanted to quick and easy way to switch between different versions of Java.

If I was using a debian variant of Linux(Ubuntu/Mint etc.), I could have used

sudo update-alternatives --config java

But am using a Mac, hence wrote this …

jvm() {
 export JAVA_HOME=`/usr/libexec/java_home -v "$1"`
 java -version
}
