How can we stop a thread in Java?

Whenever we want to stop a thread from running state by calling stop() method of Thread class in Java. This method stops the execution of a running thread and removes it from the waiting threads pool and garbage collected. A thread will also move to the dead state automatically when it reaches the end of its method. The stop() method is deprecated in Java due to thread-safety issues.

Syntax

 @Deprecated public final void stop() 

Example

 import static java.lang.Thread.currentThread; public class ThreadStopTest { public static void main(String args[]) throws InterruptedException { UserThread userThread = new UserThread(); Thread thread = new Thread(userThread, "T1"); thread.start(); System.out.println(currentThread().getName() + " is stopping user thread"); userThread.stop(); Thread.sleep(2000); System.out.println(currentThread().getName() + " is finished now"); } } class UserThread implements Runnable { private volatile boolean exit = false; public void run() { while(!exit) { System.out.println("The user thread is running"); } System.out.println("The user thread is now stopped"); } public void stop() { exit = true; } } 

Output

 main is stopping user thread The user thread is running The user thread is now stopped main is finished now
