You dont need to actually write the code to draw the figures, you need to show how to call differently the three methods and the structure of the three methods. The body of each method could have just one print line statement.

In JAVA Code:

In Draw (aSquare), you have System.out.println(draw Square);

In Draw (aCircle), you have System.out.println(draw Circle);

In Draw (aTriangle), you have System.out.println(draw Triangle);

In the main function, you should list the three call statements:

Draw (aSquare)

Draw(aCircle)

Draw(aTriangle)

The point is how to call the different methods have the same name and different implementation.
