Stopping a Runnable

Question

Hi!
I want to stop a class that implements the Runnable interface. I thought that this will be the way to do it:
I override the run() method like this:
public void run() {
   while(booleanFlag) {
      // do stuffs here
}     And I start the thread like this:
MyRunnable mR = new MyRunnable ();
Thread t= new Thread(mR);
t.start();Then when I want to stop that thread, simply make the booleanFlag to false.
I read the Java "Why Are Thread.stop ... Deprecated?", but theres nothing about Runnable. And I searched this forum topic, but it is too huge to find the answer.

Answer 1

Never mind Thread#stop() - your approach of stopping the runnable is correct and will cause the thread to terminate properly.
JavaDoc
Many uses of stop should be replaced by code that simply modifies some variable to
indicate that the target thread should stop running. The target thread should check this
variable regularly, and return from its run method in an orderly fashion if the variable
indicates that it is to stop running.However, you'll have to make sure that your flag is declared volatile. If you do not add the volatile flag, your thread may actually access a cached version of the running state and not react to another thread changing the field.
