Java: set timeout on a certain block of code?

Question

Is it possible to force Java to throw an Exception after some block of code runs longer than acceptable?

Answer 1

Instead of having the task in the new thread and the timer in the main thread, have the timer in the new thread and the task in the main thread:

public static class TimeOut implements Runnable{
    public void run() {
        Thread.sleep(10000);
        if(taskComplete ==false) {
            System.out.println("Timed Out");
            return;
        }
        else {
            return;
        }
    }
}
public static boolean taskComplete = false;
public static void main(String[] args) {
    TimeOut timeOut = new TimeOut();
    Thread timeOutThread = new Thread(timeOut);
    timeOutThread.start();
    //task starts here
    //task completed
    taskComplete =true;
    while(true) {//do all other stuff }
}
