What are Java concurrency utilities?
Java concurrency utilities are classes and interfaces that help manage multiple threads in Java applications, making it easier to write concurrent programs.
Can you give me some examples of these utilities?
Sure! Some common Java concurrency utilities include ExecutorService, CountDownLatch, and Semaphore.
How does ExecutorService work?
ExecutorService is an interface that provides a higher-level replacement for managing threads. It allows you to submit tasks for execution and manage their lifecycle.
What is the difference between CountDownLatch and Semaphore?
CountDownLatch is used to wait for a set of operations to complete, while Semaphore controls access to a resource by maintaining a set number of permits.
