所以最近,我一直试图制作自己的马里奥游戏(对我自己,可能是为了展示我的其他朋友).游戏包括按钮.当我点击其他游戏中的按钮时,它会发出声音.我很想将这个功能添加到我的游戏中.问题是,它没有发挥作用.我的源代码是：

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class JButtonClick {

    JButton test = new JButton("Click Me!");
    JPanel panel = new JPanel();

    public void playSound(String soundName)
     {
       try 
       {
        AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(soundName).getAbsoluteFile());
        Clip clip = AudioSystem.getClip();
        clip.open(audioInputStream);
        clip.start();
       }
       catch(Exception ex)
       {
         System.out.println("Error with playing sound.");
         ex.printStackTrace( );
       }
     }


    public JButtonClick() {
        JFrame frame = new JFrame("Button-Click test");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.pack();
        frame.add(panel);
        frame.setSize(800, 600);
        frame.setResizable(true);
        frame.setVisible(true);

        panel.add(test);

        test.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
            {
             playSound("JButton.wav");
            }
        });
    }
    public static void main(String[] args) {
        new JButtonClick();
    }
}

我的.wav文件与此类在同一个包中.但它没有播放我想要的声音,而是说：

我究竟做错了什么？！

解决方法:

这是因放置.wav文件而导致的问题.

根据您的问题,您已将它放在与此类相同的包中,这就是您获取FileNotFoundException的原因.

让我解释一下新文件(路径名)的工作原理：

Javadoc约File说：

A pathname, whether abstract or in string form, may be either absolute or relative. An absolute pathname is complete in that no other information is required in order to locate the file that it denotes. A relative pathname, in contrast, must be interpreted in terms of information taken from some other pathname. By default the classes in the java.io package always resolve relative pathnames against the current user directory.

>您在eclipse中运行此应用程序然后将.wav文件直接放在项目中(src文件夹外),如下所示：

AudioSystem.getAudioInputStream(new File("Jbutton.wav"));

>您也可以尝试将其放在资源文件夹中.

AudioSystem.getAudioInputStream(new File("resources/Jbutton.wav"));
