How to block the internet for some applications in my MacBook?

I want to block the internet for some applications in my MacBook. Is there any option to block outgoing and incoming connection? I don't want to use third party applications. Please let me know if anyone knows how to do that.

What applications? If you know the ports being used by the application you could block those ports in your router.

But we need more detail and context in order to offer better instructions.
