// File 1 - Conversion.java
package temperature;
public class Conversion {
 public double convert(int f) {
  double c = 5.0/9*(f-32);
  return c;
 }
}
                    
// File 2: Test.java
package mypack;
import temperature.*;
import java.util.Scanner;
class Test {
 public static void main(String[] a)
 {
  Conversion c=new Conversion();
  Scanner s=new Scanner(System.in);
  System.out.print("Enter Temp in (F): ");
  int f = s.nextInt();
  double res = c.convert(f);
  System.out.print("Temp in Cel. = "+res);
 }
}
