program should be in java language

(Geometry: n-sided regular polygon) In an n-sided regular polygon, all sides have the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). Design a class named Regu1 arPolygon that contains: A private int data field named n that defines the number of sides in the polygon with default value 3 . - A private double data field named side that stores the length of the side with default value 1. n A private double data field named x that defines the x-coordinate of the polygon's center with default value 0 . A private double data field named y that defines the y-coordinate of the polygon's center with default value 0 . - A no-arg constructor that creates a regular polygon with default values. - A constructor that creates a regular polygon with the specified number of sides and length of side, centered at (0,0). - A constructor that creates a regular polygon with the specified number of sides, length of side, and x - and y-coordinates. - The accessor and mutator methods for all data fields. The method getPerimeter () that returns the perimeter of the polygon. The method getArea () that returns the area of the polygon. The formula for computing the area of a regular polygon is Area=4tan(n)ns2 Draw the UML diagram for the class then implement the class. Write a test program that creates three RegularPolygon objects, created using the no-arg constructor, using Regul arPolygon (6,4), and using Regularpolygon (10, 4 , 5.6,7. 8 ). For each object, display its perimeter and area
