What are Java concurrency utilities?
Java concurrency utilities are classes and interfaces that help manage multi-threading and synchronization in Java applications.
Can you give me examples of these utilities?
Sure! Some common Java concurrency utilities include ExecutorService, CountDownLatch, and Semaphore.
How do I use ExecutorService in my code?
You can use ExecutorService to manage a pool of threads. For example, you can create a fixed thread pool using Executors.newFixedThreadPool(int nThreads).
What is the difference between CountDownLatch and CyclicBarrier?
CountDownLatch allows one or more threads to wait until a set of operations in other threads completes, while CyclicBarrier is used to make a set of threads wait for each other to reach a common barrier point.
