1-) Java - multi thread  stackoverflow

ThreadTest.java

public class ThreadTest

{

   public static void main(String [] args)

   {

      MyThread t1 = new MyThread(0, 3, 300);

      MyThread t2 = new MyThread(1, 3, 300);

      MyThread t3 = new MyThread(2, 3, 300);

      t1.start();

      t2.start();

      t3.start();

   }

}

MyThread.java

public class MyThread extends Thread

{

   private int startIdx, nThreads, maxIdx;

   public MyThread(int s, int n, int m)

   {

      this.startIdx = s;

      this.nThreads = n;

      this.maxIdx = m;

   }

   @Override

   public void run()

   {

      for(int i = this.startIdx; i < this.maxIdx; i += this.nThreads)

      {

         System.out.println("[ID " + this.getId() + "] " + i);

      }

   }

}

And some output:

[ID 9] 1

[ID 10] 2

[ID 8] 0

[ID 10] 5

[ID 9] 4

[ID 10] 8

[ID 8] 3

[ID 10] 11

[ID 10] 14

[ID 10] 17

[ID 10] 20

[ID 10] 23
