Question

Dice Rollers( write java)

Write a complete thread class to represent rolling dice. The thread takes a parameter that represents how many dice are being rolled at once and how many times to roll.

When the thread is run, it rolls the specified number of dice the specified number of times. The thread counts for how many rolls the number on all dice match. This value is saved as instance data.

Write a program to create and run several threads with different numbers of dice/rolls, outputting the results.

Answer 1

Code:

import java.util.*;
import java.io.*;
class Mt implements Runnable
{
   private int dice,rolls;
   public Mt(int dice, int rolls)
   {
       this.dice=dice;this.rolls=rolls;
   }
   public void run()
   {
       Random rand=new Random();
       for(int j=0;j<dice;j++)//for every dice, roll it for rolls no. of times
       {
           for(int i=0;i<rolls;i++)
           {
               System.out.println("Thread: "+Thread.currentThread().getId()+" Dice:"+ (j+1) +" Roll:"+ (i+1) + " Result:"+rand.nextInt(6));
           }
       }
   }
}
public class Program11
{
   public static void main(String args[])
   {
       int n=3;// no. of threads
       for(int i=0;i<n;i++)
       {
           Thread obj=new Thread(new Mt(3,5));//3 is no. of dices, 5 is no. of rolls
           obj.start();
       }
   }
}

Output:
