Question

Game.java calls a function getLabel() present in board.java. When I am running Game.java, I am getting error “cannot find symbol method getLabel()” in the terminal. I am not able to correct it.

Game.java

import java.awt.*;
import javax.swing.*;
import javax.swing.JLabel;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

public class Game {

    private board b;
    private bishop bis1;
    private JLabel q;

    public static void main(String[] args) {
        Game f = new Game();
        f.start();
    }

    public void start() {
        b = new board();
        bis1 = new bishop();
        bis1.setLocation(0, 0);
        ImageIcon m = bis1.getImage();
        q = b.getLabel();

        q.addMouseListener(new Mouselist());
        b.squares[0][0].add(q);
    }

    class Mouselist implements MouseListener {

        public void mouseClicked(MouseEvent e) {
            //k.setIcon(null);
            b.squares[1][1].add(new JLabel(new ImageIcon("rook.png")));
        }

        // mouse entered the JLabel increment count and display it
        public void mouseEntered(MouseEvent e) {
            b.squares[1][1].add(new JLabel(new ImageIcon("rook.png")));
        }

        public void mouseExited(MouseEvent e) {
            b.squares[1][2].add(new JLabel(new ImageIcon("rook.png")));
        }

        // mouse was presssed (cliked and released)
        // increment counter and display it
        public void mousePressed(MouseEvent e) {
            b.squares[1][1].add(new JLabel(new ImageIcon("rook.png")));

        }

        public void mouseReleased(MouseEvent e) {
            b.squares[1][1].add(new JLabel(new ImageIcon("rook.png")));
        }
    }
}

board.java

import javax.swing.*;
import java.awt.*;
import javax.swing.JLabel;

public class board {

    public JFrame frame;
    public JPanel squares[][] = new JPanel[3][3];
    private JLabel sqk = new JLabel(new ImageIcon("knight.png"));

    public board() {
        frame = new JFrame("Simplified Chess");
        frame.setSize(1200, 800);
        frame.setLayout(new GridLayout(2, 3));

        for (int i = 0; i < 2; i++) {
            for (int j = 0; j < 3; j++) {
                squares[i][j] = new JPanel();

                if ((i + j) % 2 == 0) {
                    squares[i][j].setBackground(Color.black);
                } else {
                    squares[i][j].setBackground(Color.white);
                }
                frame.add(squares[i][j]);
            }
        }

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }

    public JLabel getLabel() {
        return sqk;
    }
}

What is possibly wrong here ?

Answer 1

Most probably you have just added the getLabel() method and haven’t yet recompiled board.java
