Thread Program

[rex tony]

Good evening to all,

public class MyThread implements Runnable {
 private String holdA = "This is "; 
 private int[] holdB = {1,2,3,4,5,6,7,8,9,10}; 
 public static void main(String args[]) { 
  MyThread z = new MyThread();     (new Thread(z)).start(); 
      (new Thread(z)).start(); 
    }
    public void run() {
    for(int w = 0;w < 10;w++) {
        System.out.println(holdA + holdB[w] + ".");      }    }  }

This is 1.
This is 2.
This is 3.
This is 4.
This is 5.
This is 6.
This is 7.
This is 8.

Here nothing special is happening, you are creating and starting two threads which run concurrently. Try the below program (added yield()) and notice how threads take turns although output isnt guaranteed in both cases.

    
public class MyThread extends Thread implements Runnable {
private String holdA = "This is ";
private int[] holdB = {1,2,3,4,5,6,7,8,9,10};
public static void main(String args[]) {
MyThread z = new MyThread();
(new Thread(z)).start();
(new Thread(z)).start();
}
public void run() {
for(int w = 0;w < 10;w++) {
System.out.println(holdA + holdB[w] + ".");
        yield();
}    
}  
}
