What is the difference between ExecutorService and Future in Java?
ExecutorService is an interface that provides a higher-level replacement for managing threads, while Future represents the result of an asynchronous computation.
Can you explain how to use ExecutorService to submit tasks?
Sure! You can use the submit()
method of ExecutorService to submit a Callable or Runnable task, which returns a Future.
What happens if I try to get the result of a Future that hasn't completed?
If you call get()
on a Future that hasn't completed, it will block until the result is available or an exception is thrown.
Are there any advantages to using ExecutorService over creating threads manually?
Yes, ExecutorService manages a pool of threads, which improves resource management and simplifies concurrent programming.
