How does ExecutorService handle task scheduling in Java?
ExecutorService in Java is a high-level API that simplifies the execution of asynchronous tasks. It manages a pool of threads and schedules tasks for execution.
What are the different types of ExecutorService implementations?
There are several implementations, including FixedThreadPool, CachedThreadPool, SingleThreadExecutor, and ScheduledThreadPool. Each serves different use cases.
Can I schedule tasks to run at a fixed rate?
Yes, you can use ScheduledExecutorService, which is a subinterface of ExecutorService, to schedule tasks at a fixed rate or with a fixed delay.
What happens if a task throws an exception?
If a task throws an exception, it will be caught by the ExecutorService, and you can handle it using a Future object to check for exceptions after task completion.
