How to stop the thread

[aishwarya lakshmi]

Stop method is deprecated in Newer version. Is there any way to stop a thread in java 1.5.

[Minhaj Mehmood]

once the overridden method run() ends thread will automatically stops.

[Minhaj Mehmood]

moreover take a look on following example

public class TestClass extends Thread{

	private boolean flag = true;

	public void shutdown(){
		System.out.println("ah!! someone killed me :(");
		flag = false;
	}
	public void run(){
		while(flag){
			System.out.println("uhu!! am still alive..");
		}
	}

	public static void main(String[] args) throws Exception
	{
		TestClass clazz = new TestClass();
		clazz.start();
		clazz.shutdown();

	}
}

Thanks for your response Minhaj kaimkhani ... Deprecated Stop method means that we should not forcefully
terminate a thread. Am i correct...

Like the text suggests, a shared thread safe variable is a good way to identify a stop condition

}

In a multithreaded environment the shared variable should declared as volatile because of visibility issues when sharing a variable between threads.

In a multithreaded environment the shared variable should declared as volatile because of visibility issues when sharing a variable between threads.

The normal approach is to have a shared variable that is protected by synchronizing on the same lock

Many thanks Minhaj kaimkhani..
