    This will require 2 steps.

    First you need to place you app in a jar file. Google should provide links to some good jar tutorials.

    Next you will need to create an installer that will package your app and a JRE (if target machine needs it). There are products out there, don't know if any are free.

    for the JRE you might as well tell your users to quickly check this link Verify Java Version to see if they have java or not. If the user doesn't the little program that checks your system will recommend the latest JRE for download.
    It's an easier way out since sometimes your program could be a mere 50KB while the JRE is like 180KB.

    EDIT:
    that's actually for the chrome install, the actual JRE is more like 20MB depending on whether you have linux, windows, or whatever and whether if its 32 bit or 64 bit. It's a lot easier to just tell the user to download from that link then to have to make a bunch of installers for specific OSs.
