Question

class Rectangle { private double length, breadth; public Rectangle(double 1, double b) { Math.max (0, 1); (0, ь); length = Math.max breadth } area () { return length public double breadth } public int compareTo (Rectangle other) { ()) if (this. area other.area 1; return if (this.area() < other.area ()) return -1; return 0; } public class Client { public static Rectangle Rectangle void main (String [] args) { Rectangle (1.2, 2.5); Rectangle (2.4, 1.5); compareTo (s); new - new = int status = r. }

a. Draw a memory diagram to illustrate the passing of parameters with respect to the method call r.compareTo(s) in the following code. More specifically, illustrate how the calling object and parameter object are referenced during the execution of the method r.compareTo(s).

b. For the same definition for class Rectangle as part a., draw the memory diagram that illustrates the storage of array and objects when the following code executes:
