Java Game - Overclock.net

Pap3r · 04-28-09

So for one of my projects in my java programming class was to create a tic-tac-toe game with a menu up top. I have the game working, and I thought the menu code was right... but I keep getting compiling errors, all pertaining to the menu code. Here are the errors:

Code:

Tool completed with exit code 1

And here's the menu section:

Code:

//Constructor
    public TicTacToe()
    {
		MenuBar mnuBar = new MenuBar();
		setMenuBar(mnuBar);

		Menu mnuFile = new Menu("File", true);
		mnuBar.add(mnuFile);
			MenuItem.mnuFileClear = new MenuItem("Clear");
			mnuFile.add(mnuFileClear);
			MenuItem.mnuFileExit = new MenuItem("Exit");
			mnuFile.add(mnuFileExit);

		Menu mnuAbout = new Menu("About", true);
		mnuBar.add(mnuAbout);
			MenuItem.mnuAboutTic = new MenuItem("About Tic-Tac-Toe");
			mnuAbout.add(mnuAboutTic);

		mnuFileExit.addActionListener(this);
		mnuFileClear.addActionListener(this);
		mnuAboutTic.addActionListener(this);

		mnuFileExit.setActionCommand("Exit");
		mnuFileClear.setActionCommand("Clear");
		mnuAboutTIc.setActionCommand("About");

That's just a little part of the constructor method. What's going on?

Code:

G:\Documents\Classes\CPT102\Task3\TicTacToe.java:34: cannot find symbol
symbol  : method setMenuBar(java.awt.MenuBar)
location: class TicTacToe
		setMenuBar(mnuBar);
		^

I think everything stems from there. Your class TicTacToe doesn't have and doesn't inherit a setMenuBar(java.awt.MenuBar) method. Can you post TicTacToe's class definition (the part with the "public class TicTacToe extends etc implements etc")?

If you're making an Applet, you're out of luck because it can't have a menubar. Otherwise if your program is contained in a java.awt.Frame, you have to call the setMenuBar method of your program's Frame instance.

Code:

G:\Documents\Classes\CPT102\Task3\TicTacToe.java:38: cannot find symbol
symbol  : variable mnuFileClear
location: class java.awt.MenuItem
			MenuItem.mnuFileClear = new MenuItem("Clear");

Maybe you mean this instead? Same goes for the rest.

Code:

MenuItem mnuFileClear = new MenuItem("Clear");

I can't really tell much without seeing the rest of your code though.
