Question: 1 / 510

What is the purpose of the join() method in threading?

To pause the execution of the current thread

To forcefully stop a thread

To ensure a thread must complete before execution continues elsewhere

The join() method is not used to pause the execution of a thread (option A) as other methods like sleep() or wait() are used for that purpose. It is also not used to forcefully stop a thread (option B), as this can cause unexpected errors in the program and is not recommended. The method does not combine two threads into one (option D), but rather it waits for a thread to finish executing before moving on to the next code. Therefore, the purpose of the join() method is to ensure a thread completes before execution continues elsewhere, allowing for more organized and coordinated execution of multiple threads.
