或者放一首歌也行
b2.addActionListener(new ActionListener(){

已经建立好一个匿名监听。。里面应该填什么代码 展开

java中打开音乐播放器的方式是使用audioclip类来播放音乐,实例如下:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
import java.io.File;
class AudioPlayDemo extends JFrame implements ActionListener {
boolean looping = false;
File file1 = new File("music\\明天会更好.wav");
AudioClip sound1;
AudioClip chosenClip;
JButton playButton = new JButton("播放");
JButton loopButton = new JButton("循环播放");
JButton stopButton = new JButton("停止");
JLabel status = new JLabel("选择播放文件");
JPanel controlPanel = new JPanel();
Container container = getContentPane();
public AudioPlayDemo() {
try {
sound1 = Applet.newAudioClip(file1.toURL());
chosenClip = sound1;
} catch(OutOfMemoryError e){
System.out.println("内存溢出");
e.printStackTrace();
} catch(Exception e){
e.printStackTrace();
}
playButton.addActionListener(this);
loopButton.addActionListener(this);
stopButton.addActionListener(this);
stopButton.setEnabled(false);
controlPanel.add(playButton);
controlPanel.add(loopButton);
controlPanel.add(stopButton);
container.add(controlPanel, BorderLayout.CENTER);
container.add(status, BorderLayout.SOUTH);
setSize(300, 130);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //关闭窗口时退出程序
}
public void actionPerformed(ActionEvent event) {
if (chosenClip == null) {
status.setText("声音未载入");
return;
}
Object source = event.getSource(); //获取用户洗涤激活的按钮
if (source == playButton) {
stopButton.setEnabled(true);
loopButton.setEnabled(true);
chosenClip.play();
status.setText("正在播放");
}
if (source == loopButton) {
looping = true;
chosenClip.loop();
loopButton.setEnabled(false);
stopButton.setEnabled(true);
status.setText("正在循环播放");
}
if (source == stopButton) {
if (looping) {
looping = false;
chosenClip.stop();
loopButton.setEnabled(true);
} else {
chosenClip.stop();
}
stopButton.setEnabled(false);
status.setText("停止播放");
}
}
public static void main(String s[]) {
new AudioPlayDemo();
}
}
只能播放wav格式的歌曲
