I have installed both OpenJDK 6 and 7. When I run "java somefile" from the command line, OpenJDK 6 is invoked. I do not want to change this default behavior. What command can I use to run my non-default OpenJDK 7 installation instead?

(I am used to running "python somefile" to invoke the default Python, "python2.7 somefile" to use Python 2.7 specifically and "python3 somefile" to use Python 3 specifically.)

You could bind an alias to the specific java versions. Just add the following lines to your $HOME/.bashrc:

alias java6='/path/to/java6/bin/java'

alias java7='/path/to/java7/bin/java'

Same for javac and you should be fine ;-)
