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 $0.$
