e98. Allowing an Application with Live Threads to ExitAn application will automatically exit when there are no non-daemon threads running. In other words, a live daemon thread does not prevent an application from exiting.A thread must be marked as a daemon thread before it is started. It cannot become a daemon thread after it is started. This means that you could not implement, for example, a thread pool where the threads become daemon threads only when inactive. // This class extends Thread class MyThread extends Thread { MyThread() { // Thread can be set as a daemon thread in the constructor setDaemon(true); } // This method is called when the thread runs public void run() { // Determine if this thread is a daemon thread boolean isDaemon = isDaemon(); } } // Create the thread Thread thread = new MyThread(); // Thread can be set as daemon by the creator thread.setDaemon(true); // Start the thread thread.start();
