Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int houses = input.nextInt();

//your code goes here
if (houses >= 3){
double h = houses;
double dollar = 2 / h;
double convert = dollar * 100;
int percentage = (int)Math.round(convert);
System.out.println(percentage);
}
}
}

This is my code and I get the first two samples correct but then the next three that i cannot see are wrong and i do not know why. I am new to coding so please explain any answers very easily

Answer 1

Ben Szydlowski , use Math.ceil method to calculate percentage instead of Math.round.

Why do you write double convert = dollar *100; ?
