Code to be modified:

import java.util.Scanner;
public class Hwk3 {
public static void main (String[] args) {
int males, females,pairs;
int diff=0;
Scanner stdin = new Scanner(System.in);

System.out.println(" Butterfly Estimator ");
System.out.print("Enter the estimated males population: ");
males = stdin.nextInt();
System.out.print("Enter the estimated females population: ");
females = stdin.nextInt();

pairs=males*females;

if (males>females)
{
diff = males - females;
System.out.println("Male Difference :" +diff);
}
else if (females > males)
{
diff=females - males;
System.out.println("Female Difference"+diff);
}

System.out.println("Possible mating pairs is : "+pairs);

}
}

Explanation / Answer

Program:

import java.util.Scanner;
import java.text.DecimalFormat;
public class Hwk3 {
   public static void main (String[] args) {
       int males, females,pairs;
       int diff=0;
       double growthfactor,ratiofactor,potentialpopulation;
       Scanner stdin = new Scanner(System.in);
       DecimalFormat df0 = new DecimalFormat("#");
       DecimalFormat df1 = new DecimalFormat("#.0");
       DecimalFormat df3 = new DecimalFormat("#.000");

       System.out.println(" Butterfly Estimator ");
       System.out.print("Enter the estimated males population: ");
       males = stdin.nextInt();
       System.out.print("Enter the estimated females population: ");
       females = stdin.nextInt();

       pairs=males*females;
       growthfactor=Math.sqrt(pairs);

       if (males>females)
       {
           diff = males - females;
           System.out.println("Male Difference :" +diff);
       }
       else if (females > males)
       {
           diff=females - males;
           System.out.println("Female Difference"+diff);
       }
      
       System.out.println("Possible mating pairs is : "+pairs);
       System.out.println("Growth Factor is : "+df3.format(growthfactor));
      
       if (males/females == 0)
       {
           ratiofactor = Math.sqrt(diff);
       }
       else
       {
           ratiofactor = growthfactor/(males/females);
       }
      
       System.out.println("Ratio Factor is : "+df1.format(ratiofactor));
      
       potentialpopulation = Math.pow(2, (int) ratiofactor);
      
       System.out.println("Potential Population is "+df0.format(potentialpopulation));
   }
}
