Question
Select the correct answer
Which of these method wakes up all the threads?
Options:
start()notify()wakeAll()notifyAll()
Solution
To determine which method wakes up all the threads, let’s analyze the options provided:
-
start(): This method is used to start a thread. It doesn’t wake up any existing waiting threads; instead, it initiates a new thread of execution.
-
notify(): This method is used to wake up a single thread that is waiting on the object's monitor. If multiple threads are waiting, only one will be awakened.
-
wakeAll(): This is not a standard method in Java or similar programming languages, so it does not apply.
-
notifyAll(): This method is used to wake up all threads that are waiting on the object's monitor. It allows all waiting threads to compete for the lock.
Final Answer
The correct answer is notifyAll(), as this method wakes up all the threads waiting on the object's monitor.
