Java Concurrency: CountDownLatch Explained

Make one thread wait for multiple threads to finish Have you ever had a situation where one thread needs to wait until multiple other threads complete their work? For example, imagine that your application starts five independent tasks, and you want the main thread to continue only after all five tasks have completed. How would you implement that in Java? One very useful solution is CountDownLatch. In this video, I'll explain what CountDownLatch is, how await() and countDown() work, and then we'll walk through a practical Java example where one thread takes longer than the others. #java #concurrency #multithreadinginjava #multithreading #countdownlatch #javafundamentals
