我创建了一个简单的井字游戏GUI游戏。我想通过将按钮上显示的内容从仅文本“ X”和“ O”更改为精美的图形“ X”和“ O”（通过提供jpg或png文件）来扩展它，并且还使用.wav文件添加声音。
这是我的游戏代码：（它的工作原理非常完美。我只需要扩展方面的帮助即可。谢谢）

要将图像分配给JButton，可以使用构造函数或以下方法：
JButton myButton = new JButton(new ImageIcon("D:\\icon.png"));
setIcon(new ImageIcon("D:\\icon.png"));
当然要提供您自己的文件路径。
要播放一些.wav声音，可以使用以下方法：
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
public class MusicPlayer {
private Clip clip;
public void play() {
try {
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("D:\\sound.wav").getAbsoluteFile());
clip = AudioSystem.getClip();
clip.open(audioInputStream);
clip.start();
}
catch(Exception ex) {
System.out.println("Error with playing sound.");
ex.printStackTrace();
}
}
}
