The FileWriter has an optional second boolean argument. If you pass it true, it will operate in append mode.

Always capitalize class names. This is a universally-observed convention. Failure to do so confuses other programmers.

The "Illegal Start of Expression" compiler screech is almost always caused by a curly-brace leak.

The class Local does not have a display method. However class Simple does. You can instantiate Simple in your main method and call that instance's display method.

Note the change I made here. In a GUI app, you should make its main
routine be a run() method. You need to do this so that all events received by your app go in an orderly fashion into the event queue. The invoke later method runs your run method.

    package ourgame;
    import javax.swing.*;
        public class Frame implements Runnable
        {
                public Frame()
                {
                        JFrame frame = new JFrame();

                }
                public void run()
                {
                        frame.add(new Board());
                        frame.setTitle("2-D Test Game");
                        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                        frame.setSize(700,365);
                        frame.setVisible(true);
                        frame.setLocationRelativeTo(null);
                }


                public static void main(String[] args){
                     Frame f = new Frame();
                     javax.swing.SwingUtilities.invokeLater(f);
                }
        }

You also need to be sure that your KeyListener is focusable. See the Java tutorial on the Focus System.

Start here

typdef struct {
char key;
int count;
}count_entry;

This will do a character-integer pair, for example ('a', 3) for 'a' seen 3 times.

This is my second assignment in my Early Object Java class:

Try it; it's lots of fun
