I need help adding the mouse click events & some other small things
 

This is my assignment:

The goal of this project is to become more familiar with creating and using classes and objects in Java. In order to do so, you will create a Person class. Your class will keep track of how many parts are not shown, display the next item when a method is called, and reset.

I need to have these methods included.

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



This is the code I have written so far (along with the Circle and Square, which aren't included).
