Hi. The code below is to play a song but needs to stop when the user types the number "1." How do you make it so the public Reminder(int seconds) will stop which will then make the song stop? After it stops, I want to be able to do other things so I don't want the program to end.


Thanks for any help.

You can put riminder on a separate thread. Also it looks like you want it to be a singleton.
In the TimerTask, use reference to interrupt the thread (not currentThread()) also in the while loop use volatile boolean run and implement abort() method that will set run=false;

volatile boolean run = true;

public void abort(){
run = false;
}

while(nBytesRead != -1 && run){
...
}


Also, if you are going to make it part of GUI, use KeyEvent and KeyEventListener to trap pressed keys.
