Design patterns are established solutions to common software design problems, and they play a crucial role in Java development. In this topic, we explore various design patterns such as Singleton, Factory, Observer, Decorator, Strategy, and more. Each pattern addresses specific challenges and provides a blueprint for writing well-structured, maintainable, and scalable code. Understanding design patterns helps developers to write code that follows best practices, promotes code reuse, and makes it easier to maintain and extend applications over time.
