Thread: I/O of text file

Hi i have to make this program that will read a message from another text file and surround each occurence of an abbreviation with <> brackets. and the write the marked message to a different file. The program must beable to read from a text file that contains the abbreviations and a text file that contains the message. Could someone please tell me if I am on the right track?

    package abbreviationstest;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.FileWriter;
    import java.util.Scanner;
    import java.io.FileNotFoundException;
    /**

    public class abbreviationsTest
    {
    public static void main(String[] args)
    {
    String fileName = "abbreviations.txt";
    Scanner inputStream = null;
    System.out.println("The file " + fileName + " contains the following lines:");
    try
    {
    inputStream = new Scanner(new File(fileName));
    //messageInputStream = new Scanner(new File(fileName));
    }
    catch(FileNotFoundException e)
    {
    System.out.println("Error opening the file " + fileName);
    }
    while (inputStream.hasNextLine())
    {
    String line = inputStream.nextLine();
    System.out.println(line);
    }
    inputStream.close();
    String message = "message.txt";
    //FileOutputStream// messageOutputStream =
    try
    {
    FileOutputStream outputStream = new FileOutputStream(new String(message));
    System.out.println("The file " + message + " contains the following lines:");
    Scanner keyboard = new Scanner(new File(message));
    String newMessage = message;
    do
    {
    newMessage = keyboard.next();
    outputStream.toString();
    }
    while(newMessage.matches(message));
    {
    System.out.print(newMessage);
    }
    }
    catch(FileNotFoundException e1)
    {
    System.out.println("Error opening the file " + message);
    }
    }
    }

Please post your code properly indented. Follow Java's naming conventions and begin class names with capital letters.

Do you have an example file you're using to test this with? If so, post that too.

How do test for the existence of abbreviations?

A FileOutputStream is not appropriate for writing text files. Try PrintWriter, perhaps with a BufferedWriter.

Yes I have an example file of abbreviations and the message that uses these abbreviations
