I have a code here that i have made and all of the features working fine like all the buttons and my menu items but when there is "three is a row" i want to try and have a text field on the bottom of the app that says who won either X OR O. Here is what i have so far lets see if you guys can help me out.

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JFrame;

   private JFrame window = new JFrame("Tic-Tac-Toe");


   private int buttonCount = 0;






   public SimpleTicTacToe1() {

	       JMenu fileMenu = new JMenu("File");

     		menuBar.add(fileMenu);



     		JMenuItem aboutAction =  new JMenuItem("About");

				 JMenuItem exitAction =    new JMenuItem("Exit");

				 fileMenu.add(aboutAction);

				 fileMenu.addSeparator();

      JPanel tttPanel = new JPanel(new GridLayout(3, 3, 5, 5));

      for (int row = 0; row < tttButtons.length; row++) {

            JButton btn = new JButton("   ");

            btn.setFont(TTT_BTN_FONT);

            btn.addActionListener(tttBtnListener); // add listener to ttt button

            tttPanel.add(btn);

            tttButtons[row][col] = btn;

         }

      }

It's really simple, check each row, each column and the 2 diagonals for matching symbols. There are numerous ways to do this. Here is 1 idea:

boolean checkRow(int rowNum) {

   String x,y,z;

    x = matrix[rowNum][0].getText().trim();

    y = matrix[rowNum][1].getText().trim();

    z = matrix[rowNum][2].getText().trim();

    if( x.length() > 0 && x.equals(y) && y.equals(z) )

        return true;

    else

        return false;

}

Similar code can be created for the columns, and the diagonal.

How would i output the result though.

You've created the gui so well, I'm sure you can figure this part out too.
Just add a JTextField to the bottom of your frame/jpanel. Whatever you're using.
Make sure to call JTextField's setEditable(false) method.

After you've tested the winning solution AND if you have a winning solution
then call JTextField's method: setText( "x or o");

*sigh* Oh Ryan.

Look what I've found.

Ryan you must learn to take people's advice a little better than you have been. In many cases, when people offer you pointers, they really are being helpful. When Fubarable informed you that == would not work with String comparisons, and to instead use .equals(), you did not heed this advice. You made no modification to you source code, and thus far seem to have only copied from source examples and snippets from the other users, occasionally performing some arbitrary transformation such as "TicTacToe" to "TicTacToe5", causing another bug someone helpfully mentioned. The reason people didn't try to help you in a way you found to be helpful is because we assumed you knew what the code you started with meant. Your original source from Java Forums was ultimately sourced from various other Java sources on the internet. I was satisfied by finding the first two, as sufficient evidence you weren't even sure what you had constructed.

You also seem to have misunderstood what I believe is the prevalent objective of people who offer help to others on forums. The reason there are so many who dutifully assist is that we want you to learn something. The objective is that you gain an understanding of what the code actually means, and not that "block of code X does this, and block of code Y does that." When you see a simple code example:

 JFrame frame = new JFrame();

You should have a conceptual understanding of what actually occurred in the virtual machine. You should understand that a JFrame reference was created on the stack, called 'frame', and has been assigned the value of the address of a new JFrame object created at runtime. To understand programming, and to really learn this, the terminology I've been using should not be foreign to you. If you are willing to learn how this all actually works, there will be those willing to teach you. All I can hope to achieve with this post is to motivate you enough, through either realization, a sense of pride, spite, or frankly a little embarrassment, to try and really learn programming. To write your own novel code, and quite frankly of a few smaller projects than what you're tackling right now. It's okay to write small programs when you're learning, that's how you learn.

So, do you really want to learn this?

well im majoring in comp tech and this is one of the classes that was needed so literally i've had 0 experience with java and any coding involved it takes years to learn everything about java and obviously i havent had the time to even start looking at coding.

So what do you need? For everyone to do the work/thinking for you? :crying:

[ZekeDragon]

Are you in a beginning Java course? These courses generally assume someone with no former programming experience, though I will admit they do tend to gloss over the basics far too quickly.

[Ryan09]

pretty much..no one teaches us they just give us codes to rewrite and then when task comes we have to take some of the things we went over and make a new application on our own. They dont teach us the basics thats why i have no idea what to do or where to even start.
