用Java写了一个五子棋游戏，插入背景音乐出了问题。求大神指教

用Java写了一个五子棋游戏，插入背景音乐。第一遍音乐结束就不放了，不能暂停，重新播放和循环播放等功能。我编译的时候用的是Java应用程序，不是APPlet。
package cn.edu.ouc.fiveChess;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.SourceDataLine;

import java.io.File;

public class sound {
public static boolean openorclose=false;
public void setopenorclose(boolean a){
this.openorclose=a;
}
public static void play(String fileurl) {

     try {
           AudioInputStream ais = AudioSystem.getAudioInputStream(new File(fileurl));
           AudioFormat aif = ais.getFormat();System.out.println(aif);
           final SourceDataLine sdl;
           DataLine.Info info = new DataLine.Info(SourceDataLine.class, aif);
           sdl = (SourceDataLine) AudioSystem.getLine(info);
           sdl.open(aif);
           sdl.start();    

           if(openorclose==true){
               sdl.stop();   }
           int nByte = 0;      int writeByte = 0;    final int SIZE=1024*64;      byte[] buffer = new byte[SIZE];
           while (nByte != -1) {
          nByte = ais.read(buffer, 0, SIZE);
               sdl.write(buffer, 0, nByte);
               }
           sdl.stop();
           }
       catch (Exception e) {
                e.printStackTrace();
           }
       }

}
