title: Catching results from a void method into an output file
body: <p>I am new at Java so thank you for helping!</p>
  
  <pre><code>    public static int convert (String value) {
        int temp_convert = 0;
        // Setting up new Scanner to read the User-input string
        Scanner token = new Scanner(value);
        // Take out the word "CONVERT"
        String fnc = token.next();
        // Get the temperature that needs to be converted
        int temp = token.nextInt();
        // Current unit of temperature
        String type = token.next().toLowerCase();
        if (type.equals("f")) {
           temp_convert = (int) Math.round((temp - 32)/1.8); 
           System.out.println(temp_convert + "C");
        } else if (type.equals("c")) {
           temp_convert = (int) Math.round(1.8 * temp + 32);
           System.out.println(temp_convert + "F");
        }
        return temp_convert;
     }

  <p>I am trying to get the print result from this method into an output file using PrintStream. I need whatever is lines printed in this method to be print out into the output file. How can I do this? This is the code I have so far but it doesn't produce anything in the .txt file yet.</p>
  
  <pre><code>public static void readFile (Scanner console, String file_input) throws FileNotFoundException {
        // Setting up new Scanner to scan the file
        Scanner input = new Scanner (file_input);
         // Prompt user for output file's name
        System.out.print("Output file name: ");
        String name_output = console.next();
        PrintStream file_output = new PrintStream(new File(name_output));
        System.out.println("YazLang program interpreted and output to .txt file!");
        System.out.println();
        while (input.hasNext()) {
           String value = input.nextLine().toLowerCase();
           if (value.startsWith("convert")) {
              int concert_temp = convert(value);
              file_output.println(concert_temp);
           } else if (value.startsWith("range")) {
              range(value);
           } else if (value.startsWith("repeat")) {
              repeat(value);
           }
        }
     }
