江湖救急java读取两个wav文件有关问题_J2SE

江湖救急啊，java读取两个wav文件问题
各路大侠，江湖救急啊！
我想用java播放两个wav文件，比如说是1.wav和2.wav，首先播放1.wav再播放2.wav但是不能将其分开播放
比如不能使用下面的程序：
AudioStream au;
InputStream in1 = new FileInputStream("1.wav");
au = new AudioStream(in1);
AudioPlayer.player.start(au);
InputStream in2 = new FileInputStream("2.wav");
au = new AudioStream(in2);
AudioPlayer.player.start(au);
也就是说不能调用两次的AudioPlayer.player.start();
只允许调用一次AudioPlayer.player.start();
我想问的是如何将两个wav文件都读入inputstream而且在AudioPlayer.player.start(au)的时候可以首先播放1.wav的声音再播放2.wav的声音。谢谢

------解决方案--------------------------------------------------------
InputStream in1 = new FileInputStream( "1.wav ");
au1 = ew AudioStream(in1);
AudioPlayer.player.start(au);
InputStream in2 = new FileInputStream( "2.wav ");
au2 = new AudioStream(in2);
List<AudioStream> list=new java.util.ArrayList<AudioStream>();;
list.add(a1);
list.add(a2);
for(AudioStream au:list){
AudioPlayer.player.start(au);
}

合并两个WAVE文件到1个，看来得用第三方组件，不知JAVA本身有没有这样的API可用。

用泛型控制下

list 容器类专门放置流然后你一个一个的去放吧

Java code

try {    Process process = Runtime.getRuntime().exec("cmd /c copy 1.wav+2.wav 3.wav");  //调用Ping命令    InputStream in1=new FileInputStream("3.wav");         AudioStream au =new AudioStream(in2);      au.player.start(au);    //结束后也可以将新的wav删除  }catch (Exception  e)    {      e.printStackTrace();      }        }

linux下：
Java codetry {    Process process = Runtime.getRuntime().exec("cp>1.wav+2.wav 3.wav");  //调用cp命令    InputStream in1=new FileInputStream("3.wav");         AudioStream au =new AudioStream(in2);      au.player.start(au);    //结束后也可以将新的wav删除  }catch (Exception  e)    {      e.printStackTrace();      }        }
