Write a method that takes a RegularPolygon as a parameter, sets its number of sides to a random integer between 10 and 20 inclus
Sergio [31]

Answer:

import java.lang.Object

import java.lang.Math

public class RegularPolygon  extends java.lang.Object{

  public void randomize(RegularPolygon c){

       int min = 10, max1 = 20;

       double  min1 = 5, max1 = 12;

       double range = (max - min) + 1;

       double range1 = (max1 -min1) + 1

       int side = (Math.random() * range) + min;

       double len = (Math.random() * range1) + min1;

       c.setNumSides(side);

       c.setSideLength( len);

 }

 public static void main(String[] args) {

    RegularPolygon r = new RegularPloygon();

    randomize(r);

 }

}

Explanation:

The randomize method accepts a regular polygon class as its only parameter and assigns a random number of sides and the length of these sides with the 'Math.random' function.
