Encapsulation in Java is the process of wrapping data (variables) and the code that acts on that data (methods) together as a single unit, typically a class. Encapsulation in Java is achieved using: Private data members, Public getter and setter methods. Benefits: Data Control: You can make a class read-only (by providing only getters) or write-only (by providing only setters). Validation: Setters allow you to add logic to validate data before it is saved (e.g., ensuring an age is not negative). Security: It protects sensitive internal states from unauthorized modification. Maintainability: You can change the internal implementation of a class without breaking the code that uses it.…
