    It's possible to have several different JDKs installed on a system.
    Only one java and javac program can be referenced by the OS without full paths. Any of the tools for the JDKs can be executed by using the full path to the tool. The java program installed by with a JRE will have other hidden ties (eg the Registry on Windows) to the OS so browsers can use it. I don't know how to tell a browser to use a java plugin other than the currently(last) installed one.
    If you don't understand my response, don't ignore it, ask a question.

    For Windows: possibly using the Java console (to be found in the control panel), but to be honest I've never really had a need to so I don't really know for sure.

    Additional note: since the security-harassment in the media last year surrounding the Java browser sandbox, browsers (most notably Firefox and Chrome) tend to disable the Java plugin when it gets too old.

    What do you mean by: java program? Is it in a JRE or a JDK?
    You only need one. I have more than one for occasional testing.

    what version number is shown when you open a command prompt window and enter:
    java -version
    Also what version number is shown in the browser's java console when you execute an applet?

    You could get rid of the other versions as they aren't being used.

    You only need one JRE. You could get rid of all the others that you are not using.
