Java Program to Find Interior and Exterior Angle of Regular Polygon when Number of Sides of Polygon is Given

import java.util.*;
public class Main
{
   public static void main(String[] args)
   {
        //number of sides of polygon is declared
        int N = 8;
        // formula to find the interior and exterior angle of the polygon
        int interiorAngle = (N-2)*180/N;
        int exteriorAngle = 360/N;
        System.out.println("The interior angle of the polygon is " + interiorAngle + " deg");
        System.out.println("The exterior angle of the polygon is " + exteriorAngle + " deg");
   }
}

Output:

The interior angle of the polygon is 135 deg
The exterior angle of the polygon is 45 deg
