java - 将 .wav 和 .png/.jpg 文件添加到 GUI

Question

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，并使用 .wav 文件添加声音。

这是我的游戏代码:(它运行完美..我只需要扩展方面的帮助..谢谢)

要将图像分配给 JButton，您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"));

当然提供您自己的文件路径。

要播放一些 .wav 声音，您可以使用以下命令:

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();
            }

    }
}
