I just made a Risk game and I use j4exe to compile it to an exe file. However - There are a few bugs like the Random class that gives the same number 100 times in a row and it claims that it cant find the Scanner class that was implemented in 1.5.0 and such things.
Then I would like to know how you guys show your work to people with a computer with no compiling tools og anything.
Do you create exe files too? I see you upload your .jar files, but dont you have to have a little knowledge about java to run such one without using Eclipse og something semilar?
Well, At least I would like to know how you profs do 
And btw:
