Which method is used to wait for a thread to complete its execution?join()wait()stop()terminate()

To wait for a thread to complete its execution in programming, the correct method to use is join(). This method is called on a thread object and causes the calling thread to wait until the thread whose join() method is called has completed its execution.

Here’s a brief overview of the options provided:

1. join(): Suspends the calling thread until the thread represented by this instance terminates. This is the correct method for waiting for a thread to finish.

2. wait(): This method is typically used in a synchronized context to wait until another thread invokes the notify() or notifyAll() method for that object. It does not relate to waiting for a thread to finish.

3. stop(): This method was used to forcibly stop a thread and is deprecated because it can leave shared variables in an inconsistent state.

4. terminate(): This is not a standard method in most threading libraries in programming languages like Java or Python.

In conclusion, when you want to ensure that a thread has completed its execution before proceeding, you should use join().
