    Default I am the most terrible file reader.....

    I have a program that has 2 options. 1;to read a file and 2, to add a file:





    The text file looks like this:

    Yellow Submarine
    Beatles
    Rock
    Welcome to my life
    Simple plan
    Alternative
    Break
    Three Days Grace
    Rock

    There are 9 files and 3 arrays. One for songs, one for artists and one for genre

    the count is declared like this:

    int[] count = {0};


    NOW... If the user reads the program, then adds a file and then reads it again it will look like this:


    Yellow Submarine
    Beatles
    Rock
    Welcome to my life
    Simple plan
    Alternative
    Break
    Three Days Grace
    Rock
    NewSong
    NewArtist
    NewCateg
    Yellow Submarine
    Beatles
    Rock
    Welcome to my life
    Simple plan
    Alternative
    Break
    Three Days Grace
    Rock
    NewSong
    NewArtist
    NewCateg

    There are 24 files.... How can I fix this?

    static void Read (String[] Song, String[] Artist, String[] Category, int[] count, String[] database) throws IOException    //to open and view the database
        {
            BufferedReader reader = new BufferedReader (new FileReader (database [0] + ".txt"));
            System.out.println ("Here is your music collection: ");
            //  System.out.println ("First is a song, followed by the artist and last is the category: ");
            String line = null;
     
     
            while ((line = reader.readLine ()) != null)
            {
                Song [count [0]] = (line);
                line = reader.readLine ();
                Artist [count [0]] = (line);
                line = reader.readLine ();
                Category [count [0]] = (line);
                count [0]++;
            }
     
            reader.close ();
     
            System.out.println ("Song" + "                        " + "Artist" + "                          " + "Category"); // spacing is correct
            System.out.println ();
     
     
            for (int i = 0 ; i < count [0] ; i++)
            {
                System.out.print (Song [i]);
                for (int j = 0 ; j < (30 - Song [i].length ()) ; j++)
                    System.out.print (' ');
     
                System.out.print (Artist [i]);
                for (int j = 0 ; j < (30 - Artist [i].length ()) ; j++)
                    System.out.print (' ');
     
                System.out.print (Category [i]);
                for (int j = 0 ; j < (29 - Category [i].length ()) ; j++)
                    System.out.print (' ');
                System.out.println (' ');
     
            }
            System.out.println ("There are: " + count [0] + " songs");

    Can you post the code for the program?
    Be sure to wrap your code with[code=java]<YOUR CODE HERE>[/code] to get highlighting
