Output always 0.0

-----------------------------------

Hi, this program is suppose to get how much percent the first numbers is divided by the total. No matter what you enter the percent is always 0.0 Why is this happening?

Thanks in advance.




import java.util.Scanner;

public class Percent {

public static void main (String

I think it's because it rounds it because it's an integer. Try casting it as a double like this (double)num1 / (double)Total * 100

Remember when putting the value into the percent1 variable, you have to cast it all back to an integer. 

e.g. percent1 = (int)((double)num1 / (double)Total * 100);

I still get an output of 0.0 Does this happen when you guys run it? Maybe theres a problem with my java?

Read up on data types, which is the reason why you get that out put. Try change all the data types to float, or double depends how many decimals you want it to go up to

Let's try making this code look a little bit nicer too.

import java.util.Scanner;

public class Percent {
    public static void main(String

And, how about we break out the prompt logic.

import java.util.Scanner;

public class Percent {
    public static void main(String
