Answer
Encapsulation protects object integrity by controlling access to its data.
Encapsulation involves hiding an object's fields and requiring interaction through methods. This prevents unauthorized changes, ensuring data validity. For example, a Product class with a private 'price' and a public 'setPrice' method can validate inputs, such as non-negative prices.
