Answer 1

Use MouseAdapter()

An abstract adapter class for receiving mouse events. The methods in this class are empty. This class exists as convenience for creating listener objects. So you need to implement only the method you like such as following example:

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class MainClass extends JPanel {

  public MainClass() {

      addMouseListener(new MouseAdapter() { 
          public void mousePressed(MouseEvent me) { 
            System.out.println(me); 
          } 
        }); 

  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.getContentPane().add(new MainClass());

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    frame.setSize(200, 200);
    frame.setVisible(true);
  }
}
