Executor Framework Deep Dive | ThreadPool, Future & Callable | Java Full Course #56

In this Java multithreading video, we begin with a complete introduction to the Executor Framework in Java and understand why it is preferred over manually creating threads.

This video explains the complete hierarchy of the Executor Framework, including the Executor interface, ExecutorService interface, and the important methods used to submit and manage tasks. We then take a deep dive into ThreadPoolExecutor, which is the core class behind most thread pools in Java.

You will also learn how the Executors utility class helps us create ready-made thread pools such as FixedThreadPool, CachedThreadPool, SingleThreadExecutor, and ScheduledThreadPool.

In this video, we cover:
