Consider the following statements. public class Rectangle {private double length; private double width; public Rectangle() {length = 0; width = 0;} public Rectangle(double l, double w) {length = l; width = w;} public void set(double l, double w) {length = l; width = w;} public void print() {System.out.println("Length = " + length + "; Width = " + width + "
" + + " Area = " + area() + "; Perimeter = " + perimeter());} public double area() {return length * width;} public void perimeter() {return 2 * length + 2 * width;} public void makeCopy(Rectangle otherRect) {length = otherRect.length; width = otherRect.width}} Rectangle tempRect = new Rectangle(14, 10); Rectangle newRect = new Rectangle(9, 5); What are the values of the instance variables of newRect after the following statement execute? newRect.makeCopy(tempRect);
A) length = 14; width = 10
B) length = 9; width = 5
C) length = 14; width = 5
D) None of these

The makeCopy method copies the values of the instance variables of the calling object (newRect) to the values of the instance variables of the parameter object (tempRect). So, after the statement newRect.makeCopy(tempRect) executes, the instance variables of newRect will have the values of the instance variables of tempRect, which are length = 14 and width = 10.
