Java Multithreading and Parallel Programming Masterclass - Parallel Array Search with CountDownLatch

The video tutorial introduces the Countdown Latch, a synchronization tool in the Java API, explaining its functionality and use cases. It compares Countdown Latch with Semaphore, highlighting the differences. The tutorial includes a practical implementation using a simple program to demonstrate how Countdown Latch works with multiple threads. The program searches for a value in an array using threads, showcasing the Countdown Latch's role in synchronizing thread completion. The tutorial concludes with a brief introduction to the Cyclic Barrier, another synchronization primitive.

How does a Countdown Latch differ from a semaphore?

Describe the process of using multiple threads to search for a value in an array with a Countdown Latch.

What is the significance of the number of threads in the context of a Countdown Latch?
