how to return null to int method
<p>iam new to programming.iam wrking on a quiz game software. here i want a count down to be printed as "3,2,1,go...go...go" </p>

<pre><code>  package t2;

import java.util.Scanner;
import java.util.Timer;
import java.util.TimerTask;

public class Stopwatch {
static int interval;
static Timer timer;

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    int delay = 1000;
    int period = 1000;
    timer = new Timer();
    interval = 3;
    System.out.println("3");
    timer.scheduleAtFixedRate(new TimerTask() {

        public void run() {
            System.out.println(setInterval());

        }
    }, delay, period);
}



 private static final int setInterval() {
    String go="go...go...go";
    if (interval == 2)
    {

        timer.cancel();
        return go;
    }

      return --interval;

}
}
</code></pre>

<p>this says that setInterval() has int as return value.if i place <code>System.out.print("go");</code>
in the place of <code>return go;</code> it prints go and prints 1 which is out of requirement. please any buddy can tell me how to do this.</p>
