Java 8 Functional Interfaces: Runnable vs Callable Explained with Examples

Описание: In this video, I explain the difference between Runnable and Callable interfaces in Java 8 with simple examples.

✅ Runnable Interface:
Used to create a thread.
run() method → does not return a result.
Cannot throw checked exceptions.

✅ Callable Interface:
call() method → returns a result (Future object).
Can throw checked exceptions.
Useful for tasks that need a return value.
