Question
Can i please get help in this Introductory Java Homework?Please avoid using advace concept as its an intro course. (Sorry for all these photos, The code wont take you much time as its a basic course. )
This code needs to be modified with the following changes given. Please put in proper comments and identation. (instructions are given). Ill definetly give you a thumbs up rating. Thanks!
Code to be modified:
import java.util.Scanner;
public class Hwk3 {
public static void main (String[] args) {
int males, females;
int totalButterflies, sexRatio, ratioVariance,genderDifference, matingPairs;
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();
totalButterflies = males + females;
sexRatio = males / females;
ratioVariance = males % females;
genderDifference = males-females;
matingPairs = males*females;
System.out.println(" Total Butterflies: " + totalButterflies );
System.out.println("Sex Ratio : " + sexRatio );
System.out.println("Variance : " + ratioVariance );
System.out.println("Gender Difference: " + genderDifference );
System.out.println("Mating Pairs : " + matingPairs );
}
}
/*
Sample Output:
Butterfly Estimator
Enter the estimated males population: 33
Enter the estimated females population: 22
Total Butterflies: 55
Sex Ratio : 1
Variance : 11
Gender Difference: 11
Mating Pairs : 726
