This is an Intro

Java hw. Please do not use advance concepts like arrays. The code to be modified and instructions are provided. Indenatation and comment

instructions provided as well.

Please make sure to include output(text form).No need to rush but please be sure to follow all the instructions. WIll def leave positive feedback. THanks!

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);

}
}

Solution

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));
   }
}
