What is high cohesion and low coupling in software design?

Can you explain what high cohesion and low coupling mean in software design?

High cohesion refers to how closely related and focused the responsibilities of a single module are, while low coupling indicates that modules are independent and interact minimally.

Why is it important to have high cohesion and low coupling?

It's important because high cohesion makes modules easier to understand and maintain, while low coupling enhances flexibility and reusability.

Can you give an example of high cohesion and low coupling?

Sure! A class that handles user authentication is highly cohesive because all its methods relate to that single responsibility. If it interacts with a separate class for database operations, that's low coupling.

How do I achieve high cohesion and low coupling in my projects?

You can achieve this by defining clear module responsibilities, using interfaces for interactions, and avoiding unnecessary dependencies.
