Question
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
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 =
nx s²
4 x tan
(5)
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 Regular Polygon (6, 4), and using Regular Polygon (10,
4, 5.6, 7.8). For each object, display its perimeter and area.
