threads - maha and khalid cross

[gayathri bhushan]

Which methods may cause a thread to stop executing?
1 sleep();
2 stop();
3 yield();
4 wait();
5 notify();
6 notifyAll()
7 synchronized()
Select all correct answers.
the correct answers are 1,2,3,4.
but in khalid it is given clearly as "calls to methods suspend(), sleep() and wait() do not stop a thread..they only cause the thread to move out of its running state. a thread will stop only when it is done executing the run method"
which one is right...please answer me

hi gayathri
i think that the answers are right, when a thread executes, it is in the running state, so it is in the run() method, those methods may cause the thread to stop executing, taking it out of the running state, meaning stopping it from executing the run() method.
'stop executing' doesn't mean thread is dead!
anyone pls correct where i'm wrong
