(Geometry: n-sided regular polygon) An n-sided regular polygon's sides all have the same length and all of its angles have the same degree (i.e., the polygon is both equilateral and equiangular). Design a class named RegularPolygon that contains: 1 A private int data field named n that defines the number of sides in the polygon. A private float data field named side that stores the length of the side. 1 A private float data field named x that defines the x-coordinate of the center of the polygon with default value 0. I A private float data field named y that defines the y-coordinate of the center of the polygon with default value 0. 1 A constructor that creates a regular polygon with the specified n (default 3), side (default 1), x (default 0), and y (default 0). The accessor and mutator methods for all data fields. 1 The method getPerimeter() that returns the perimeter of the polygon. 1 The method getArea() that returns the area of the polygon. The formula for n × s² computing the area of a regular polygon is Area 4 X tan Draw the UML diagram for the class, and then implement the class. Write a test pro- gram that creates three RegularPolygon objects, created using RegularPolygon(), using RegularPolygon(6, 4) and RegularPolygon(10, 4, 5.6, 7.8). For each object, display its perimeter and area.
