Encapsulation and information hiding are related but distinct object-oriented design concepts: encapsulation means grouping the essential features of a concept together and/or establishing an access boundary around them (e.g., via private or protected members), while information hiding means concealing the internal representation or implementation details of a component behind an interface so that other code depends only on that interface. These concepts belong to the domain of software design principles within object-oriented programming, and connect closely to the broader principles of cohesion (increased by encapsulation) and coupling (reduced by information hiding).
