    Default output error

    No output :(

    i am trying to get the program to out put the translated to morsecode text. it should reade from the file and translate to morse and output the code...



    Java Code:
     
    import javax.swing.JOptionPane;
    import java.io.*;
    public class Morse
    {
        public static void main(String[] args)throws IOException
        {
            String userInput;
            final String SENTINEL = "0";//for exiting program when entered
            //object creation
            Translate text = new Translate();
            //getting user input to be translated
            do
            {
                userInput = JOptionPane.showInputDialog("Please enter what you wish to translte to Morse code (no punctuation).");
                String compare = userInput.toUpperCase();
                String[] codedText = new String[compare.length()];
                codedText = text.translateHere(compare);
                text.toString(userInput, codedText);
            }while(!userInput.equals(SENTINEL));
        }//end main
    }//end class
    Java Code:
    import java.io.File;
    import java.io.IOException;
    import java.util.Scanner;
    
    public class Translate {
     public Translate()
        {
        }//end default constructor
        public String[] translateHere(String s)throws IOException
        {
            String compare = s, codedLine = "";  //userInput toUpperCase
            int length = compare.length();  //length of userInput
            String line, file = "Morse.txt";// variable holding file name and variable for each letter/number
            char code;
            //Constants
            final int MAX = 36;
            //Arrays
            char[] morseLetter = new char[MAX];
            String[] morseCode = new String[MAX];
            String[] newMessage = new String[length];
            //putting user input in a character array;
            char[] userLetters = compare.toCharArray();
            //object creation
            File openFile = new File(file);
            Scanner inFile = new Scanner(openFile);
            int  counter = 0;
            while(inFile.hasNext())
                {
                    line = inFile.next();
                    code = (char)line.charAt(0);
                    //System.out.println(code);
                    morseLetter[counter] = code;
                    morseCode[counter] = inFile.next();
                    counter++;
                }//end nested while loop
            for(int j = 0; j < length; j++)
            {
                for(int k = 0; k < MAX; k++)
                {
                    if(userLetters[j] == morseLetter[k])
                    {
                        newMessage[j] = morseCode[k];
                    }
                }//end nested for loop
            }//end for loop
            return newMessage;
        }//end method that completes translateion
        public String toString(String a, String[] b)
    {
       System.out.println("Input: " + a);
       System.out.println("Output:");
       String output = "";
       for(int i = 0; i < b.length; i++)
       {
          output = output + b[i];
       }
       return output;
     }//end toString method
    }//end Translate Class
