Stopping the thread in midway using Thread.stop() is not a good practice. More appropriate way is to make the thread return programmatically. Let the Runnable object use a shared variable in the run() method. Whenever you want the thread to stop, use that variable as a flag.
EDIT: Sample code
class MyThread implements Runnable{
private Boolean stop = false;
public void run(){
while(!stop){
//some business logic
}
}
public Boolean getStop() {
return stop;
}
public void setStop(Boolean stop) {
this.stop = stop;
}
}
public class TestStop {
public static void main(String[] args){
MyThread myThread = new MyThread();
Thread th = new Thread(myThread);
th.start();
//Some logic goes there to decide whether to
//stop the thread or not.
//This will compell the thread to stop
myThread.setStop(true);
}
}
