Printing mouse cordinates

[Nathan Papes]

My goal is to print the mouse coordinates when the mouse is clicked within a frame and displayed in a text box. Here is my code so far, please help!

import java.awt.*;
import java.awt.event.*;

public class Mouse extends Frame implements MouseListener, WindowListener {

	TextField text = new TextField(20);
	
	public static void main(String[] args){
		Mouse mse = new Mouse();
		mse.setSize(300, 300);
		mse.setVisible(true);
		
		
	}
	Mouse(){
		super("Mouse Position");
		setLayout(new FlowLayout());
		addWindowListener(this);
		add(text);
	
	}
	
	public void mouseClicked(MouseEvent e){
		text.setText(Point getPoint());
		
	}
	 public void windowClosing(WindowEvent e) { //Method to properly close the window
         dispose();
         System.exit(0);
 }
}

Two things:
1) line 24 contains invalid syntax.
2) You are right to use a MouseListener, but you never start using it.

That said, your code has a few more problems. Some severe, like not implementing all of the methods of MouseListener and WindowsListener. My advice:
1) Drop AWT. Use Swing instead. AWT is very old and very limited. Swing can do just about anything AWT can do, plus more.
2) Use anonymous inner classes for your listeners. That way you can extend the adapter classes, and you don't need to implement all methods. For instance:

/* old
        addWindowListener(this);  
        add(text);  
      
    }  
      
    public void mouseClicked(MouseEvent e){  
        text.setText(Point getPoint());  
          
    }
*/
// new:
        addWindowListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e){  
                text.setText(e.getPoint().toString());  
            }
        });  
        add(text);  
    }  

Your class then doesn't need to implement MouseListener or WindowListener anymore.

Speaking of the WindowListener, if you use a JFrame you can achieve the same behaviour with just one line:

setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

I agree that AWT is dated, but for following my project guidelines it was asked to be used.

And I've given you all the help you need. Just re-read my post carefully.

I have the code compiled and the program is functional, for that, thanks for all your help!

I have one more quick question(not a huge deal though), the program does not always return the coordinate values when the mouse is clicked??
I don't have much experience with java and troubleshooting, do you know an explanation for this?

mouseClicked() doesn't always fire, better to use mousePressed()

Thanks!
