  3. Re: my loops are not working like they should

    Re: JRadioButton Won't Respond

  8. Re: Advice on removing duplicates from a .txt file while writing to an array

    You could use a HashMap, and generate strings.hashCode() as the key. This would eliminate duplicates. And to get an array Collections<String> c = hm.values()
    Object[] array = c.toArray()

    That is not correct. The initial values of the array are all 0's so it checks all 10 numbers to see if they match. Here is an example output after the first roll.

    [SOLVED] Re: Simulation for Grid Game?

    You didn't remove the semicolon from the end of the for loop. for (trial = 1; trial<=500;trial++) no semicolon. Other then that, you are sending the same numbers through the for loop, so even if it...
