What is the primary purpose of using Callable in Java?
- To create an instance of a Runnable interface
- To create threads that run a specific task
- To define and execute a periodic task

The primary purpose of using the Callable interface in Java is to run tasks asynchronously and return a result. Unlike the Runnable interface, Callable tasks can return a result or throw an exception. This is commonly used with the Executor framework for managing concurrent tasks that require results.
