The method that can be used to make the main thread to be executed last among all the threads is join().

Here's a step by step explanation:

1. The join() method in Java is used to pause the current thread until the specified thread dies. This method waits for a thread to die.

2. If we call the join() method on a thread, the currently running thread will block until the thread we join with has completed.

3. So, if we want the main thread to finish last, we can call the join() method on all other threads from the main thread. This will ensure that the main thread will wait until all other threads have completed, and thus it will finish last.

Please note that stop(), sleep(), and call() methods have different uses and they cannot ensure that the main thread will be executed last among all the threads.
