title: Java Fahrenheit to Celsius loop (with methods)
body: <p>I need to convert Fahrenheit to Celsius in a Java program with methods, a <code>for</code> loop statement, and no user input. It is supposed to display Fahrenheit temperatures 0 through 20 and it's Celsius conversions. Any solutions?</p>
  
  <pre><code>import java.util.Scanner;
  
  public class celsiusTempTable
  {
  public static void main(String[] args)
  {
        System.out.println("Fahrenheit to Celsius Conversion Table");
      double tempC = celsiusConversion(tempC);
        int tempF = fahrenheit(tempF);
      displayData(tempF, tempC);
  }
      public static int fahrenheit(int F)
      {
         for(F = 0; F &lt;= 20; F++)
         {
            return F;
         }
      }
      public static double celsiusConversion(double C)
  {
          Scanner input = new Scanner(System.in);
          for(int F = 0; F &lt;= 20; F++)
      {
      C = (5.0/9.0) * (F - 32);
      return C;
      }
  }
  public static void displayData(int F, double C)
  {
          for(F = 0; F &lt;= 20; F++)
      {
        System.out.println("\nThe temperature in Fahrenheit is: " + F);
        System.out.println("The temperature in Celsius is: " + C);
          }
  }
  
  }
