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.
