What is the primary difference between Runnable and Callable interfaces?

Callable can be scheduled for future execution.
Callable can run without being wrapped in a thread.
Runnable allows returning a result.
Runnable can be used for multi-threading.

The primary difference between Runnable and Callable interfaces is that Callable allows you to return a result from the computation, whereas Runnable does not. Callable is typically used when you need a result from a task that can be scheduled for future execution, while Runnable is a simple interface for a task that does not return a result.
