What interface do you implement for a class to fulfill a task but not return any value?

  1. Callable

  2. Executors

  3. Runnable

  4. Thread

The correct answer is: Runnable

The correct interface to implement for a class to execute a task but not return a value is the Runnable interface. Option A, Callable, is incorrect because it is used when a value needs to be returned. Option B, Executors, is incorrect because it is a class that provides static utility methods for executing tasks. Option D, Thread, is incorrect because it is a class rather than an interface.
