Fahrenheit to Celsius conversion yields only 0.0 and -0.0

Question

I\'m on the 8th chapter (Methods, Constructors, and Fields) of my Java methods book and I\'m having a problem with one of my exercises.

The provided code is Tempera

Answer 1

import java.util.Scanner;
public class HelloWorld {

    public static void main(String[] args) {
        Scanner reader = new Scanner(System.in);  // Reading from System.in

        System.out.println("Enter  the number of Fahrenheit temperatures to convert to Kelvins");
// opts for the user to enter a number 

        int F = reader.nextInt() ; // Scans the next token of the input
        double f = 5/9d;
        System.out.println(f);
        double x = F -32;
        System.out.println(x);
        double K = (f*x)+ 273.0; // the formulae to calculate temperature  in Kelvin
        System.out.println( +F + " Fahrenheit is equal " +K + " Kelvins" ) ;
        reader.close();




    }
