The proper way to stop a running thread is to set a variable that the thread checks occasionally. When the thread detects that the variable is set, it should return from the run() method. 
Note: Thread.suspend() and Thread.stop() provide asynchronous methods of stopping a thread. However, these methods have been deprecated because they are very unsafe. Using them often results in deadlocks and incorrect resource cleanup. 

    // Create and start the thread
    MyThread thread = new MyThread();
    thread.start();
    
    // Do work...
    
    // Stop the thread
    thread.allDone = true;
    
    class MyThread extends Thread {
        boolean allDone = false;
    
        // This method is called when the thread runs
        public void run() {
            while (true) {
                // Do work...
    
                if (allDone) {
                    return;
                }
    
                // Do work...
            }
        }
    }
