I have provided four classes.  Look at the Shape, Rectangle and Square classes and answer the following questions:

1. What would each of the following print:
a.
Shape s = new Shape("banana");
System.out.println(s);

b.
Square s = new Square(4);
System.out.println(s);

c.
Rectangle s = new Rectangle(2, 4);
System.out.println(s);

2. Which of the following are legal assignments?
a. Shape s = new Square(4);
b. Square s = new Shape("banana");
c. Shape s = new Rectangle(2, 4);
d. Rectangle s = new Shape("banana");

3. What would each of the following print:
a.
Shape s = new Square(4);
System.out.println(s);

b.
Shape s = new Rectangle(2, 4);
System.out.println(s);
