JGO is pretty great for java game making...i have been visiting there for about a week or so now and have learned tons..didnt know the quiz was to see if you could compile and run a program but now that kevin said that it clears things up for me haha
if you are only wanting to make games then you should probably check out c++...not saying java isnt great but if you plan to do it working for a company eventually you will probably be using c++ over java...with that said im starting game making with java and loving it
although from what ive done so far its really just a bunch of for loops and if statements lol...but that may be just because im starting out with platform type games...anyway hope you find what you are looking for
