Create a class called Area that implements the Comparable interface.

An area is a rectangle constructed to be width x height.

Comparison: Two areas are considered "equal" if their perimeters are the same. An area is considered "less than" another area if its perimeter is smaller. An area is considered "greater than" if its perimeter is larger.

Constructor

public Area (int width, int height) throws IllegalArgumentException

width, height are the width and height of the region

throws IllegalArgumentException for non-positive width or height

You must implement the Comparable interface

You must override the equals method to fulfill the definition of equals.

There are no "setters" or "getters"

Below code has error.

Constructor did properly compare two equal-perimeter areas
