HELP!!! I got NULL!

-----------------------------------

void readerwriter ()
        throws java.io.IOException
    {
        String input;
        boolean higher;
        int number = 0;
        FileReader fra = new FileReader ("ProjectData.txt");
        BufferedReader bfra = new BufferedReader (fra);
        do
        {
            for (int count = 0 ; count < bfra.readLine ().length () ; count++)
            {
                if (Character.isDigit (bfra.readLine ().charAt (count)) == true)  //basically, im trying to look at my txt file one line at a time, and looking for a number one char at a time
                {
                    number = (int) bfra.readLine ().charAt (count);
                }
            }
        }
        while (bfra.readLine () != null);
        fra.close ();
        //

This is a part of a method i used.

I cannot run this part because the bolded segnment gets:
java.lang.NullPointerException
        at GameMethods.readerwriter(GameMethods.java:427)
        at FinalProjectMain.main(FinalProjectMain.java:18)

I do not know why. Can anyone help?

Each time you  bfra.readLine () it reads a new line so your for loop, your if, and your assignment are three different lines.
