You must provide all coordinates comprehensively. (5 points) 4.2 Write a new method, named position2(Graphics g), that draws a stickman standing at the top of the stair. And sketch your designed position with coordinates. (4 points) 4.3 Modify the class Stickman by adding another stickman standing at the top of the stair after the program is executed. (1 point)
