How to print 1 to 100 using threads

Question

Hi,
I have 5 threads (t1, t2, t3, t4, t5) and I want to print the values as
t1 - 1
t2 - 2
t3 - 3
t4 - 4
t5 - 5
and again
t1 - 6
t2 - 7 and goes on upto t5-100 and the condition is that it should print
as 1,2,3,4,5,6,7,...,99,100.
Any help would be greatly appreciated

What aboutimport java.util.Stack;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class ConcurrentCounter implements Runnable
     private static volatile Stack<Integer> stack = new Stack<Integer>();
     public static void main(String[] args) {
          for (int i = 100; i >= 0; i--) {
               stack.push(i);
          ExecutorService executor = Executors.newFixedThreadPool(5);
          for (int i = 0; i < 5; i++) {
               executor.execute(new ConcurrentCounter());
          executor.shutdown();
     public void run() {
          while (true) {
               synchronized(stack) {
                    if (stack.isEmpty()) break;
                    System.out.println(Thread.currentThread().getName() + ": " + stack.pop());
               try {
                    Thread.sleep(100);
               } catch (InterruptedException e) {
                    // ignore
}
