swing - Adding a mouse listener to image or image Icon in java

How can I to add mouse listener to image or imageIcon in Java?

Here is my code. I want to do anything with imageIcon after mouse click on it.

public class Bubbles extends JPanel {
    
    public static final int LINE_OUT = 440;
    int x = 20;
    int y = 50;
    int v = 4;
    
    Image img = new ImageIcon("res/lop.png").getImage();
    BackSide back;
    

    public Bubbles(int x, int y, int v, BackSide back) {
        this.x = x;
        this.y = y;
        this.v = v;
        this.back = back;
        setFocusable(true);
        
    }
    
 
    public void move() {
        if (y >= 440) {
            y = 0;
        } else {
            y += v;
        }
    }

}

What you can do is that you can use a JLabel and set the ImageIcon to it. make the JLabel transparent by using setOpaque(false). Then, add listener to it and do whatever you want to do :)
