Introduction Design patterns play a vital role in software development, helping developers solve specific problems and improving the maintainability and scalability of code. Singleton pattern and prototype pattern are two common creational design patterns, which are used to control the creation and replication of objects respectively. This article will explore the definitions of these two patterns, the problems they solve, implementation examples, as well as their differences and application scenarios. Overview of Singleton Pattern Definition Singleton Pattern is a creational design pattern…

What is the Simple Factory Pattern? The Simple Factory Pattern is a creational design pattern that uses a factory class to instantiate different types of objects. Based on the parameters passed in, the factory class decides which specific class to create. The Simple Factory Pattern is often used to reduce the client code's dependence on specific classes, ensuring that the code is easier to maintain and extend. In the Simple Factory Pattern, the factory class is responsible for the object creation logic, and the client does not need to worry about how to create the object, but only needs to...
