help me with this java program use simple logic

(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 RegularPo yygon 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. 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. a The accessor and mutator methods for all data fields. - The method getPerimeter ( that returns the perimeter of the polygon. The method getArea() that retums 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 and then implement the class. Write a test program that creates three RegularPo7ygon objects, created using the no-arg constructor, using RegularPolygon (6,4), and using RegularPolygon (10, 4,5,6,7.8). For each object, display its perimeter and area
