Can you help me solve this?

1. Draw a stack diagram showing the state of the program just before findCenter returns. Include all variables and parameters, and show the objects those variables refer to.

2. Draw a stack diagram showing the state of the program just before distance returns. Show all variables, parameters, and objects.

3. What is the output of this program? (Can you tell without running it?)

public static void main(String[] args) { Point blank = new Point(5, 8); Rectangle rect = new Rectangle(0, 2, 4, 4); Point center = findCenter(rect); double dist = distance(center, blank); System.out.println(dist); }
