What are design patterns using encapsulation?

Can you explain what design patterns using encapsulation are?

Sure! Design patterns are typical solutions to common problems in software design. Encapsulation is a principle that restricts access to certain components, which helps in maintaining the integrity of the data.

How does encapsulation improve code maintainability?

Encapsulation improves maintainability by hiding the internal state of an object and requiring all interaction to be performed through an object's methods. This reduces dependencies and makes it easier to change the implementation without affecting other parts of the code.

Can you give an example of encapsulation in a design pattern?

Certainly! The Factory Method pattern is a great example. It encapsulates the instantiation of objects, allowing a class to defer instantiation to subclasses, which can help manage and control object creation.

What are some other design patterns that use encapsulation?

Other design patterns that utilize encapsulation include the Singleton pattern, which restricts instantiation to one object, and the Adapter pattern, which allows incompatible interfaces to work together by encapsulating the interface.
