How to get output on screen with java?

Java Help(easy): Why do I get an output of 0?

• import java.util.Scanner; public class Converter { public static void main(String[] args) { Scanner input = new Scanner(System.in); int num; int fahrenheit; int celsius; System.out.print("\nEnter Fahrenheit temperature: "); fahrenheit = input.nextDouble(); celsius = (5/9)*(fahrenheit-32); System.out.printf("%f Fahrenheit is %f Celsius\n\n", fahrenheit, celsius); } } ====================================== I tried making the variables a double, but that didn't work. No matter what I input, I either get 0 or -0....

• Answer:

  5 and 9 are integers. Therefore, when you divide 5 / 9, you get 0. 0 * (fahrenheit - 32) = 0. In order to avoid this, you need to use doubles (5.0 / 9.0), not ints (5 / 9): public class Converter { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("\nEnter Fahrenheit temperature: "); double fahrenheit = input.nextDouble(); double celsius = (5.0/9.0)*(fahrenheit-32.0); System.out.printf("%f Fahrenheit is %f Celsius\n\n", fahrenheit, celsius); } }
