0. Programming and UML. Complete the following problems. They involve writing Java programs and creating UML class diagrams in some cases:

1. Design a class named Square to represent a square. The class contains: A double data field named width that specifies the width of the square. The default values are 1 for the width. .no-arg constructor that creates a default square constructor that creates a square with the specified width. method named getArea) that returns the area of this square. method named getPerimeter) that returns the perimeter. Draw the UML diagram for the class and then implement the class. Write a test program that creates two Square objects-one with width 40 and the other with width 35.9. Display the width, area, and perimeter of each square in this order
