在JLayer中使用一个线程时，如何停止当前播放歌曲？

Question

I recently used a solution to the one-thread-at-a-time problem whe using Jlayer to play mp3 songs in Java. But this solution by Kaleb Brasee didn't hint at how you could stop the player, ie how could one then call player.close()?

Kaleb's code was:

Executor executor = Executors.newSingleThreadExecutor();  
executor.execute(new Runnable() { public void run() {  
 /* do something */  
} });

and this is the code I put in run()

if(player != null) player.close();  

try{  
player = new Player(new FileInputStream(musicD.getPath()));  
player.play();  
}catch(Exception e){} 

The problem is that much as this solves the problem of keeping the gui active while the music plays (in only one other thread -- what i'd wanted), I can't start playing another song :-(

What could I do?

Answer 1

This is very similar to the other question, you can simply play one audio frame at a time, and check a flag if it should pause, in your case stop, playing.

Answer 2

Well, after tweaking with the code, I realized that replacing the current thread solves the problem; it allows you to start playing a different song even if the previous one hasn't finished yet.

This is the new code:

Executor executor; //a class member

Doing this every time you want to play a song simply replaces the existing song's thread,
thus allowing you to play another song regardless of the progress of the other

executor = Executors.newSingleThreadExecutor();
executor.execute(new Runnable() { public void run() {
/* do something */
} });
