Explain about implementation patterns present in Android

Question

Accepted Answer

Implementation patterns in Android are design patterns that help in structuring and organizing code for better maintainability and scalability.

MVC (Model-View-Controller) pattern separates the application into three main components to improve code organization and reusability.
MVVM (Model-View-ViewModel) pattern separates the UI logic from the business logic, making it easier to test and maintain.
Singleton pattern ensures that a class has only one instance and provides a global point of access to it.
Factory pattern is used to create objects without specifying the exact class of object that will be created.
Observer pattern allows an object (Observer) to watch another object (Subject) and be notified of changes.
Adapter pattern converts the interface of a class into another interface that a client expects.
Builder pattern separates the construction of a complex object from its representation, allowing the same construction process to create different representations.
Decorator pattern adds behavior to objects dynamically without affecting the behavior of other objects of the same class.
