Matching Game in Java

Post Views: 8,186

Hello Friends, I hope you are doing fine. Today I am going to share a Matching Game in Java. Matching games are games in which players have to find match similar elements. As the name implies, participants need to find a match for a word, picture, or card. I have developed this game when I was learning Java. In this game you can load your own images using Load button. I had used NetBeans IDE to develop this game. This game also play sounds on different events i.e when player wins or loose or finds correct match. Now I am sharing it, so that anyone need it can use it. By the way a Java learner can learn a lot from this code. So, Here is the code..

MainFrame.java

package game;

import java.awt.Image;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.MouseEvent;

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.InputStream;
import java.util.ArrayList;
import javax.swing.ImageIcon;
import javax.swing.JFileChooser;
import javax.swing.JOptionPane;

        int x = 0;
        for (int i = 0; i < tiles.length; i++) {
            tiles[i] = new Tile(icons[x], new ImageIcon(getClass().getResource("/images/logo.png")));
            tiles[i].addActionListener(this);
            gamePanel.add(tiles[i]);
            if ((i + 1) % 2 == 0) {
                x++;
            }
        }
        title.setText("Score: " + score);
        shuffle();

    }

            icons[i] = createIcon(img);
        }

    }

        BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
