Class GeometricObject is superclass of classes Circle and Rectangle. Design an interface named Colorable with a void method named howToColor$().$ Every class of a colorable object must implement the Colorable interface. Design a class named square that extends Geometricobject and implements Colorable. Implement howToColor to display the message Color all four sides.

The square class contains a data field side with getter and setter methods, a no$-$arg constructor to create a square with side $1,$ a constructor for constructing a Square with a specified side, and toString method.

Draw a UML diagram that involves Colorable, Square, Circle, Rectangle, and Geometricobject. Write a test program $($Assignment$4)$ that creates an array of five Geometricobjects. For each object in the array, display its dimension$($s$),$ area and invoke its howToColor method if it is colorable.

Geometricobject are:

A square with side $3\mathrm{.}0$

A circle with radius $4\mathrm{.}0$

A square with side $5\mathrm{.}0$

A rectangle with width $6\mathrm{.}0$ and height $7\mathrm{.}0$

A square with side $8\mathrm{.}0$
