Hi friend,

Use the following code:

import java.util.*;

class MyThread extends Thread{
MyThread(String s){
super(s);
start();
}
public void run(){
for(int i=0;i<5;i++){
System.out.println("Thread Name :"
+Thread.currentThread().getName());
try{
Stack stac = new Stack();
Thread.sleep(1000);
System.out.print ("Push ");
for (int j = 1; j <= 5; j++)
{
System.out.print (stac.push(new Integer(j) ));
}
System.out.print ( "Pop " );
while ( !stac.empty() )
{
System.out.print ( stac.pop() );
}
}catch(Exception e){}
}
}
}
public class CreateStack{
public static void main(String args[]){
System.out.println("Thread Name :"+Thread.currentThread().getName());
MyThread m1=new MyThread("My Thread 1");
MyThread m2=new MyThread("My Thread 2");
}
}
Thanks
