Thread: Timer not running.

Hello, this code is not running.

package countdown;
 
import java.util.Timer;
import java.util.TimerTask;
 
public class counter {
    public static TimerTask run() {
    	System.out.println("hello");
    	return null;
    }
    public static void main(String args[]) {
    	Timer t = new Timer();
        t.schedule(run(), 0, 1000);
    }
}

This is the console message.

Exception in thread "main" java.lang.NullPointerException: Cannot read field "lock" because "task" is null
at java.base/java.util.Timer.sched(Timer.java:400)
at java.base/java.util.Timer.schedule(Timer.java:249)
at countdown/countdown.counter.main(counter.java:14)

The run() method returns null instead of an instance of the TimerTask class that the schedule method requires.
Change run to return a valid instance of the TimerTask class.

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

You have the code, now move the declaration of an instance of the TimerTask class outside of the main method.
