Thread: JAVA Applet Timer

Hello! I'd like to start off with saying I am a real beginner with JAVA. I am creating a mouse-click game where you need to click the button as many times as you can within 15 seconds. I have the button and the score working, all I need is a timer that can count down from 15. I know there are swing timers and there are util timers and it would be prefered if I could use a util timer. Here is the code i have so far:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.util.Timer;
import java.util.TimerTask;

public class MouseCickGame extends Applet implements ActionListener
{
int counter = 0;
Button Click = new Button ("Click Me!");
Label Score = new Label (" Score: ");
Label Timer = new Label ();

public void init ()
{
GridLayout grid = new GridLayout (3, 3);
setLayout (grid);
add (Click);
Click.addActionListener (this);
add (Score);
add (Timer);
}


public void actionPerformed (ActionEvent ae)
{
if (ae.getSource () == Click)
{
counter += 1;
}


Score.setText (" Score: " + counter);
}
}

I need to know how I can implement a timer into this code then have the button dissapear and the score displayed somewhere on the applet. Thanks!

Well I preferred the util timer mostly because i figured it would be easier for me to comprehend, but if you say the swing timer is more efficient and easier to use than i suppose that would be another possibility. Thanks for your help!

Basically the intention of this timer is to make a game where you click the button however many times you can within 15 seconds, after the 15 seconds the button is supposed to disappear. Could you possible help me with the coding because I seem to be having issues with the timer.

Okay I have a new update. I have a timer working but now the game itself is not showing. All the buttons and labels I am attempting to add are not showing. Here is my code:

import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
 
public class TimerDisplay extends JLabel implements ActionListener
{
    GridLayout grid = new GridLayout (3, 3);
    int count = 14;
    int counter = 0;
    JButton Click = new JButton ("Click Me!");
    JLabel Score = new JLabel ("                                         Score: ");
    JPanel p = new JPanel ();
    public TimerDisplay ()
    {
        super ("Remaining Time: 15 secs", JLabel.CENTER);
        p.setLayout (grid);
        p.add (Click);
        Click.addActionListener (this);
        p.add (Score);
        Timer t = new Timer (1000, this);
        t.start ();
        this.add (p);
        p.setVisible (true);
        Click.setVisible(true);
        Score.setVisible(true);
    }
 
 
    public void actionPerformed (ActionEvent ae)
    {
        this.setText ("Remaining Time: " + count-- + " secs");
        if (ae.getSource () == Click)
        {
            counter += 1;
        }
        if (count == -1)
        {
            count = 0;
            remove (Click);
        }
        Score.setText ("                                         Score: " + counter);
    }
 
 
    public static void main (String arg[])
    {
        JFrame f = new JFrame ();
        f.setSize (500, 500);
        f.addWindowListener (new WindowAdapter ()
        {
            public void windowClosing (WindowEvent e)
            {
                System.exit (0);
            }
        }
        );
        TimerDisplay c = new TimerDisplay ();
        f.getContentPane ()
            .setLayout (new BorderLayout ());
        f.getContentPane ()
            .add (c, BorderLayout.CENTER);
        f.show ();
    }
}

Iv tried extending JFrame but it always screws up the timer. As far as im aware of, code "this.add (p)" should add the panel to the frame shouldnt it? What would you recommend I alter to the code?

But if im not extending anything what am i adding tha panel to? What is the alternate code to add the panel if im not extending anything? Would it make sense to at least extend JFrame? The only reason im extending JLabel is because thats what the timer is running off of.
