Java: Getters and Setters Design

A large API surface increases complexity and potential for error.

Exposing a large API surface in a class can make the system more complex and harder to maintain. Each public method increases the class's responsibilities and the potential for misuse. For example, if a 'Product' class in an e-commerce application exposes setters for every field, it may become difficult to maintain business rules or ensure data consistency, as clients could alter states without respecting intended constraints.
