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…

Introduction In software development, design patterns are an effective way to solve common problems. The Builder Pattern is one of the commonly used creational design patterns, which aims to simplify the construction process of complex objects. This article will explore the implementation of the Builder Pattern in Golang, compare the differences with other creational patterns, and discuss its applicable scenarios. Overview of the Builder Pattern The Builder Pattern builds a complex object by using a builder object. This pattern can separate the construction process of an object from its representation...

What is the Abstract Factory Pattern? The Abstract Factory Pattern is a creational design pattern that provides an interface for creating a series of related or interdependent objects without specifying their concrete classes. The Abstract Factory Pattern provides a consistent interface for clients to create different types of products. The structure of the Abstract Factory Pattern The Abstract Factory Pattern usually includes the following components: Abstract Factory Interface: defines the interface for creating products. Specific…

What is the Factory Method Pattern? The Factory Method Pattern is a creational design pattern that creates objects by defining an interface, but defers the specific implementation of the object to the subclass. This means that the Factory Method Pattern allows subclasses to decide which class to instantiate, making code expansion more flexible and easier to maintain. Compared with the Simple Factory Pattern, the Factory Method Pattern no longer relies on a single factory class, but implements object creation through an abstract factory interface. This…
