Stop thread Java
|
Show The thread is one of the important Classes in Java and multithreading is the most widely used feature, but there is no clear way to stop Thread in Java. Earlier there was a stop method that exists in Thread Class but Java deprecated that method citing some safety reasons. By default, a Thread stops when the execution of run() method finishes either normally or due to any Exception. In this article, we will How to Stop Thread in Java by using a boolean State variable or flag. Using a flag to stop Thread is a very popular way of stopping the thread and it's also safe because it doesn't do anything special rather than helping run() method to finish itself. How to Stop Thread in JavaAs I said earlier Thread in Java will stop once the run() method is finished. Another important point is that you can not restart a Thread which run() method has finished already, you will get an IllegalStateExceptio, here is a Sample Code for Stopping Thread in Java. Sample Code to Stop Thread in Java private class Runner extends Thread{ boolean bExit = false; public void exit(boolean bExit){ this.bExit = bExit; } @Override public void run(){ while(!bExit){ System.out.println("Thread is running"); try { Thread.sleep(500); } catch (InterruptedException ex) { Logger.getLogger(ThreadTester.class.getName()).log(Level.SEVERE, null, ex); } } } } Should we make bExit Volatile?Thats all on how to stop the thread in Java, let me know if you find any other way of stopping threads in Java without using the deprecated stop() method.
