What are coupling and cohesion in software design?
Coupling refers to the degree of interdependence between software modules, while cohesion measures how closely related the responsibilities of a single module are.
Can you explain why high cohesion is desirable?
High cohesion is desirable because it means that a module has a well-defined purpose, making it easier to maintain, understand, and reuse.
What about coupling? Why is low coupling preferred?
Low coupling is preferred because it reduces the dependencies between modules, allowing for easier changes and better modularity.
Can you give an example of high cohesion and low coupling?
Sure! A class that handles user authentication is an example of high cohesion. If it interacts with a separate class for database access, that's low coupling.
