我随便弄了一个程序，求大神帮忙给加一个背景音乐，最好是不需要按钮，当界面打开的时候就自动播放的，当然有按钮也可以，谢谢啦
1 package dsa; 2 import java.awt.*; 3 4 import javax.swing.*; 5 6 7 public class tianjiabeijingyinyue extends JFrame 8 { 9 private JLabel label1=new JLabel("添加背景音乐"); 10 public tianjiabeijingyinyue() 11 { 12 super("添加背景音乐"); 13 this.add(label1,BorderLayout.NORTH); 14 this.setSize(300, 300); 15 this.setBackground(Color.lightGray); 16 this.setDefaultCloseOperation(EXIT_ON_CLOSE); 17 18 this.setVisible(true); 19 20 } 21 22 public static void main(String arg[]) 23 { 24 new tianjiabeijingyinyue(); 25 26 } 27 28 }

// wait until all data is played, then close the line
line.drain();
line.close();
}

这个要用到audio包的代码好像。。。
import java.applet.Applet; import java.applet.AudioClip; import java.io.File; import java.net.MalformedURLException; import java.net.URL; import javax.swing.JTextField; public class Shengyin { int g; String b; AudioClip aau1; JTextField ss; public Shengyin(){ } public Shengyin(JTextField a){ ss=a;b=ss.getText().trim();System.out.println(b); } public void a(JTextField a){ try { ss=a;b=ss.getText().trim();System.out.println(b); URL cb1; File f1 = new File("sound/"+b+".wav"); System.out.println("zhun"+b+""); cb1 = f1.toURL(); aau1 = Applet.newAudioClip(cb1); aau1.play();//循环播放 aau.loop() 单曲 aau.stop()停止播放 g=1; } catch (MalformedURLException e) { e.printStackTrace(); } } }
