Thread: I need help with my game

So I'm working on this game for a school project and I have 2 problems
1.I do not know how to display the players score in the panel
2.Every single time the console reads the second button I click on as a 0 instead of the number underlining it

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.border.*;

	int board[][] = {
			{ 2, 11, 3, 2, 6, 5, 7, 9, 8, 1 },// numbers to fill Jbutton with
			{ 10, 6, 1, 3, 8, 12, 13, 14, 15, 4 },

1.I do not know how to display the players score in the panel

I suggest you add the playing board to a JFrame with another JPanel to display the score. The score can be printed most simply by using the g.printString( x, y, "String Here" ); in the scoring JPanel's paintComponent() method. You could add a shape of a different color behind the scores to emphasize them.

2.Every single time the console reads the second button I click on as a 0 instead of the number underlining it

Did you notice that selecting the second square actually requires 2 clicks? Is that the behavior you expected? I don't think so. It indicates that the logic in your actionPerformed() method is incorrect. It's also overcomplicated and uncommented. I suggest you think about how the game is played, write down the steps on paper, turn those into comments in your code, and program that.

This code is incorrect (hint: consider the '='):

    public void sameValues() {
        if (player1 = true) {
            P1score++;
 
        }
        if (player2 = true) {
            P2score++;
 
        }
 
    }

Comparing a boolean to true or false in a condition, like this:

if (attempt1 == true)

is unnecessary. Simply,

if ( attempt1 )

is sufficient.

Having 2 booleans, attempt1 and attempt2, is unnecessary. The attempt is either attempt1 or !attempt1.
