public class Test {
    public static void main(String[] args) {
	GamePlayer game = new GamePlayer();
	
	System.out.println(game.doSomeMove());
    }
}

class GamePlayer {
    int doSomeMove() {
	// Cause some timeout on purpose.. 7 seconds!
	Long stoptime = 7000L; 
	
	try {
	    Thread.sleep(stoptime);
	} catch (InterruptedException e) {
	    e.printStackTrace();
	}

	return 5;
    }
}

class ThreadTesting implements Runnable {
    public void start() {
    }
    
    public void stop() {
    }
    
    public void run() {
	try {
	}
	
	catch (Exception e) {
	}
    }
}

I'm not too sure on how to do this.

as you see i deliberately make the doSomeMove() return the int after 7 seconds. i want to somehow run the doSomeMove() method in a thread and check it for timeout issues. If the method takes more than 5 seconds to respond, i want to stop the thread and print "player move took too long to repsond" otherwise i return the move (the int) as normal. can anyone help me with this
