Help Creating Mouseclick Events

I need help with this code. These are my guidelines:

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 (see Section 4.6). 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.)

I wrote some code for the body parts, but I'm having trouble with the getNumLeft and the Mouseclick Events (which will reset once I have all body parts on shown). Also, each mouseclick can be made to show multiple body parts which correspond toimport java.awt.Color;
import java.awt.Graphics;
import javax.swing.JApplet;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
