How can we stop a thread in Java

In Java, stopping a thread can be a bit tricky since the Thread.stop() method has been deprecated due to its unsafe nature. Instead, it is recommended to use a more controlled approach to stop a thread gracefully. This can be achieved by using a shared variable that the thread checks regularly to determine if it should terminate.

Here is an example of how to stop a thread in Java using a boolean flag:


        public class StoppableThread extends Thread {
            private volatile boolean running = true;

            public void run() {
                while (running) {
                    // Thread task
                    System.out.println("Thread is running");
                    try {
                        Thread.sleep(1000); // Simulating work
                    } catch (InterruptedException e) {
                        Thread.currentThread().interrupt();
                    }
                }
                System.out.println("Thread has stopped");
            }

            public void stopThread() {
                running = false;
            }

            public static void main(String[] args) throws InterruptedException {
                StoppableThread thread = new StoppableThread();
                thread.start();
                Thread.sleep(5000); // Let the thread run for 5 seconds
                thread.stopThread(); // Request to stop the thread
                thread.join(); // Wait for the thread to finish
            }
        }
