JVM version manager

Is there Ruby Version Manager equivalent for the Java world?

I'm looking for tool which allow me to easily download and install a new JVMs and switch between them. For example:

jvm install <version>
jvm list //will list installed JVMs on my system
jvm use jdk1.6 //will switch my env to jdk 1.6 version, etc.
Solution

  • If you use Ubuntu you can specify which JVM you want to use via command (works only for JVM installed from apt-get or aptitude)

    sudo update-alternatives --config java

    Or by setting JAVA_HOME. Here is good tutorial:
