How do you execute a sequence thread?

How do you execute a sequence thread?

Executing threads in Sequence in Java Thing to do here is you start the thread and call the join() method on the same thread. This makes it to wait until the thread stops executing. That way order is ensured.

What are wait () notify () notifyAll ()?

The wait() method causes the current thread to wait until another thread invokes the notify() or notifyAll() methods for that object. The notify() method wakes up a single thread that is waiting on that object’s monitor. The notifyAll() method wakes up all threads that are waiting on that object’s monitor.

What is the difference between wait () notify () and notifyAll ()?

notify() and notifyAll() methods with wait() method are used to for communication between the threads. But when we use notifyAll() method then multiple threads got the notification but execution of threads will be performed one by one because thread requires lock and only one lock is available for one object.

Why wait notify and notifyAll is declared in object class instead of thread?

Hence, wait() and notify() methods are defined in Object class rather than Thread class. If wait() and notify() were on the Thread instead then each thread would have to know the status of every other thread and there is no way to know thread1 that thread2 was waiting for any resource to access.

How does sequential thread execution work in Java?

T1 prints 1, T2 prints 2, T3 prints 3 and T1 prints 4 again following strict ordering. This implementation would allow us to control any number of threads to do sequential ordered execution.

What happens when a thread is waiting for a notification?

Waiting threads must provide the option to check the state and to return back to a waiting state in case the notification has already been handled. This is why we always put calls to the wait () method in a loop. 3.4. What happens when more than one thread is waiting for notification?
