    Re: Guys, really need your help

    When I find out when neg repped me like that, they are DEAD!

    I was NOT spoonfeeding. That code was a copy/paste pretty much of their own code a few posts earlier.

    Re: Guys, really need your help

    r.nextInt() will return some random number that is a valid integer. That's from -2^32 +1 to 2^32 -1 I think. However, you could keep it as it but do this

    int k = Math.abs(r.nextInt()) % 10;

    Re: Guys, really need your help

    Array indexes aren't valid, unless your variable happens to be of type Object, then it could be I think, if you initialized it as such, for regular int type.

    Re: How to make this Java Code in NetBeans

    The user presumably means that the code works, but they don't know the logic or it or why it is what it is.

    The game goes on forever. You don't seem to have a thing that will end it.

    Re: Guys, really need your help

    The Random's nextInt() could return negatives. However, this might work for you.

    r.nextInt(Integer.MAX_VALUE)%10;

    However, if that generated 1000 and then 100, it would both go to 0 with that...

    Should have realized that. (Probably would have if I wasn't sleep deprived.)

    Re: Guys, really need your help

    Actually, you might possibly be able to use a for loop for that one, though the while should be kept as well.

    for (int k = 1; k <=10; k++)
    {


    if ( n < 0.1k) count(k-1)++;


    }

    Arrays are a collection of similar, to an extent, an Object array could hold anything for instance, types.

    It has int indexes and would, assuming it was already intiialized, and assuming you...

    That is because you are referring to the field object you created that only has the scope of the ActionListener.
