Question

I want my timer to execute the actionPerformed method only one time once it 5 seconds the time but it is writing in the console “Hello” lots of times:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.Timer;

public class X{
    public static void main(String args[]) {

        ActionListener actionListener = new ActionListener() {
            public void actionPerformed(ActionEvent actionEvent) {
                System.out.println( "Hello" );
            }
        };
        Timer timer = new Timer( 5000, actionListener );
        timer.start();
    }
}

How can I make the effect I want? Thanks

As already mentioned, it’s better to use java.util.Timer, but you can also use setRepeats() before starting:

timer.setRepeats(false);
