Java brute etc

     I need a Java application that will allow me to brute force in Java, if you have one, or can make one, it would be much appreciated.

Right, here's the Awesome Java Bruteforce (AJB):

public static void main() {
   int x = 10000;
   int guess;
   do {
      guess = new java.util.Random().nextInt();
   } while (guess * guess != x);
   System.out.println("Sqrt(" + x ") = " + guess);
}
