question to know the event in which image?

[stack]

hi,
i have a question:ex: if i have 4 images (image1, image2, image3, image4) and i want message1 appear if i click in image1, message2 appear if i click in image2, message3 appear if i click in image3, and message4 appear if i click in image4

how can I know if the mouse event in image1 or 2 or 3 or 4 without using the position of these images in the board?

i want a method to tell me the event in which image...

[John]

Use the getSource() method.

public void actionPerformed(ActionEvent e){
if(e.getSource().equals(image1)) {
    //show message 1
} else if(e.getSource().equals(image2)) {
    //show message 2
}

import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseMotionListener;
import java.awt.Graphics;
import javax.swing.ImageIcon;
import javax.swing.JOptionPane;



public class SS extends JApplet
{
private ImageIcon image1;

public void init(){
image1 = new ImageIcon("instruction.jpg");
}

public void paint(Graphics g){ //paint

 image1.paintIcon(this,g,0,0);

  addMouseListener(

    new MouseAdapter()
	 {//MouseAdapter

	 public void mousePressed(MouseEvent e){ //press

    if(e.getSource().equals(image1)) {  //msg

    System.out.printf("YOU CLICK IN IMAGE1");

	 JOptionPane.showMessageDialog( null, "GOOD MORNING ", 
    "HI",JOptionPane.INFORMATION_MESSAGE  );

} //msg

}//press
	 }//MouseAdapter

I meant to say - You never added a mouse listener to image1.

Simple doing a

addMouseListener() 

Adds the mouse listener to the root content panel. You have to add the mouse listener to the object you want it to listen to a la

image1.addMouseListener()
