        String filename = "data.txt";
        Bowler bowl = new Bowler(name, game, filename);
        System.out.println(bowl.toString());
     
     
      }
    }


    i get a NoFileFoundException for data.txt, its in the same folder as the Bowler.java file

    and then i get an ArrayIndexOutOfBoundsException: 21

    any idea how to fix them?

    The data.txt file is attached

    There is no such class as NoFileFoundException. Perhaps you mean FileNotFoundException

    Since the code posted will not even compile I doubt you get any exceptions.

    Are you the same person who has posted the exact same assignment at java-forums.org?

    OK, I take that back. I was fooled by the poor indentation and lack of brackets.

    Open a command prompt, navigate to the directory, do a ls command. The most common mistake with text files is that they are called "data.txt.txt".

    Likely the file isn't in one of the directories it normally looks (actually not likely but definitely). Where are you placing the file, and how are you running your program (for example, are you using the command-line or and IDE such as eclipse or netbeans).

    Try adding a println with 'input' around line 28-29. It should give you the path it's looking for.
