Java Program to generate random numbers ~ Hack The Dark

Hi Folks. My friend asked for a java program which can help in generating the random numbers because he's writing some sort of game. Well, I'm not a big Java fan as I still love C\C++ to write codes however after writing a revolutionary code like Space Eater Virus in Java many friends suggested me to migrate from C language to Java. I left this decision on time as of now. In order to solve the problem of my buddy I randomly or you can say shamelessly got a code from internet which was written for the same purpose. Here I'm sharing that code.....

public class Random

{

    private static long seed = 13;

    private static long a;

    private static long c;

    private static long m;



    public static void random_init(long s) {

 if (s != 0) seed = s;

    }



    public static long random() {

 seed = (a*seed + c)%m;

 return seed;

    }



    public static void main(String[] args) {

 if (args.length != 4) {

     System.out.println("usage: you must enter values for a, c, m, seed");

     return;

 }

 a = Long.parseLong(args[0]);

 c = Long.parseLong(args[1]);

 m = Long.parseLong(args[2]);

 long s = Long.parseLong(args[3]);

 random_init(s);

 for (int k = 0; k < m-1; k++) {

     System.out.println(random());

     if (k % 8 == 7) { // after 8 elements go to a new line

  System.out.println();

  try {

      Thread.sleep(1000); // sleep for a second

  } catch (Exception e) {

      System.out.println(e.getMessage());

         }



     }

 }

    }

}
