Thread: Programming Issues simple Game

Hi very New to Java,

struggling with a few fundamental principles. I have to write a noughts and crosses program, but there is a few thing I'm not quite understanding;

why some of my actionPerformed do the same thing?
how to select 'x' or '0' and then progress the game to start here's my code, might i add its incomplete areas highlighted red are the parts i'm struggling with the most , I have just added the things I will eventually need. hope its not too wishy washy. Any help would be appreciated thanks



public class NoughtsAndCrossesGame extends JFrame
{
private final int FRAME_WIDTH = 500;
private final int FRAME_HEIGHT = 500;
private int playingAreaWidth;
private int playingAreaHeight;

private int currentPlayer = 0; // 1 for player 1, 2 for player 2
// if 0 then game hasn't yet started
private String [] playerSymbols; // holds X or O as chosen by players.
private boolean gameUnderWay; // true once play has been pressed - until
// Start again is selected.
