Note: Math.PI is a static constant from the Math class. Math.tan() is a static method in the Math class, which accepts an angle in radian as its parameter. Write a test class called TestRegularPolygon. Its main() method creates three RegularPolygon objects, 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. A sample run is as follows: Polygon 1 perimeter: 3.0 Polygon 1 area: 0.43301270189221946 Polygon 2 perimeter: 24.0 Polygon 2 area: 41.569219381653056 Polygon 3 perimeter: 40.0 Polygon 3 area: 123.10734148701015

Task: Design and implement a class 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 Regular Polygon 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 centre with default value 0. ● A private double data field named y that defines the y-coordinate of the polygon's centre 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, centred 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 x side² Edit Instructions 4 × tan (1)
