1. Write a Rectangle class to hold the length and the width.

2. Write the obvious constructor.

3. Revise your constructor above such that it has the ability to detect which input is

the length and which one is the width. You will need to use the if statement here.

4. Suppose there is no if statement in the language, how can you implement the

above question? (Hint: think of Math.min and Math.max).

5. Write a constructor that takes two points as parameters. Create a Point class to

assist you. Do not store these points. What must be stored is the lengths of the two

sides, just as before.

6. Write a method to compute the perimeter of the rectangle.

7. Write a method to compute the area of the rectangle.

8. Write the toString() method for the class.

9. Write a method that returns a new Rectangle that is as double as the original one.

Do not change the existing object.
