I need help adding a mouse click event to my code

I new to java and i having a hard time adding a mouseClick event to my code. I need to get this done.

Create a Person class that draws a person. The Person class should implement the following methods:
• paintComponent – with the same signature/header of the other paintComponent methods we have written. This will paint the person.
• getNumLeft – returns the number of turns the player has left (e.g. 6 at the beginning assuming head, body, left/right arm/leg). Hint: this is named like a getter/accessor method for a reason.
• reset – which resets the number of turns left and erases the person so it is not visible
• showNext – progressively causes the next body part to be shown: head, body, left arm, right arm, left leg, right leg
• main – a static method used for testing. It should display a person object and when you click on it the next body part should show, if all parts are visible, then it should be reset so it is no longer visible. This will be removed for the final game, but will allow you to test each piece as you go, which is a good programming practice. (See the hint below for help with handling the mouse clicking.)

so far my code looks like this:

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JApplet;
import java.awt.event.*;

public class Person extends JApplet implements MouseListener
{
private int turnsleft;
private Circle Head;
private Square Body;
private Rectangle Arm;
private Rectangle Arm2;
private Rectangle leg;
private Rectangle leg2;
private Square hand;
private Square hand2;
private Rectangle feet;
private Rectangle feet2;

public void mouseClicked()
{

}

public int getNumLeft() {
return turnsleft;
}

public void reset(){
turnsleft = 6;
repaint();

}
public void showNext(){
turnsleft = turnsleft -1;
repaint();
}

public void init()
{
this.setSize(500, 400);
