MUST BE IN JAVA
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 RegularPolygon 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.
- 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 = n * s^2 / (4 * tan(pi / n))
Draw the UML diagram for the class and then implement the class.
Write a test program that creates three RegularPolygon 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.

Polygon 2 perimeter: 24.0
Polygon 2 area: 41.569219381653056
Polygon 3 perimeter: 40.0
Polygon 3 area: 123.10734148701015
