Hello there good poeple, I need some help.
I'm writing a music player which streams music from the web. If I pres the play button before the music is done buffering I want it to wait.
I tried doing something like this:
Object mutex = new Object();
public void main() {
startStreaming();
mutex.notify();
}
private void onClickPlayButton() {
mutex.wait();
}
The problem is that is...
public static synchronized void main(String[] args) throws InterruptedException {
Thread t = new Thread();
t.start();
System.out.print("X");
t.wait(10000);
System.out.print("Y");
}
What is the problem with this method?
How can I avoid such problems from now on?
