面向对象编程(Object-Oriented Programming, OOP)是一种编程范式,它使用“对象”来设计软件。下面是一些面向对象编程方面的名词中英文对照以及英文解释:
类 (Class):
- A blueprint for creating objects. Classes encapsulate data and methods to operate on the data.
对象 (Object):
- An instance of a class. Objects are the basic units of object-oriented programming.
继承 (Inheritance):
- A mechanism where a new class inherits properties and behavior (methods) from another class.
多态 (Polymorphism):
- The ability of different classes to provide a common interface, allowing objects to be treated as instances of their parent class, leading to simpler code and fewer errors.
封装 (Encapsulation):
- The bundling of data and the methods that operate on that data, restricting direct access to some of the object’s components, which is a means of preventing unintended interference and misuse of the methods and data.
抽象 (Abstraction):
- The process of picking out (abstracting) common features of objects and procedures, to create a general idea or concept that can be used to define more specific, concrete implementations.
接口 (Interface):
- A contract between a class and the outside world. When a class implements an interface, it promises to provide the behavior published by that interface.
方法 (Method):
- A code block within a class that has a name and is executed when called. They are used to perform certain actions and can return values.
消息传递 (Message Passing):
- The process by which an object sends data, in the form of a message, to another object.
构造函数 (Constructor):
- A method that is called when an object is created. It usually initializes the object’s attributes.
析构函数 (Destructor):
- A method that is called when an object is destroyed. It is used to deallocate resources held by the object.
重载 (Overloading):
- The ability to define multiple methods in a class with the same name but different signatures.
覆盖 (Overriding):
- The ability of a subclass to provide a specific implementation of a method that is already provided by one of its superclasses.
实例变量 (Instance Variable):
- A variable that is defined inside a method and belongs only to the current instance of a class.
类变量 (Class Variable):
- A variable that is shared by all instances of a class. Class variables are defined within a class but outside any of the class’s methods.

软件设计原则和设计模式是软件工程中非常重要的概念,它们帮助开发人员创建清晰、可维护和可扩展的代码。下面是一些软件设计原则和设计模式的相关名词,包括中英文对照以及英文解释:
软件设计原则 (Software Design Principles):
单一职责原则 (Single Responsibility Principle, SRP):
- A class should have only one reason to change, meaning that it should have only one responsibility.
开放封闭原则 (Open Closed Principle, OCP):
- Software entities should be open for extension but closed for modification.
里氏替换原则 (Liskov Substitution Principle, LSP):
- Objects of a derived class should be able to replace objects of the base class without affecting the correctness of the program.
接口隔离原则 (Interface Segregation Principle, ISP):
- Clients should not be forced to depend on interfaces they do not use.
依赖反转原则 (Dependency Inversion Principle, DIP):
- High-level modules should not depend on low-level modules, both should depend on abstractions.
设计模式 (Design Patterns):
单例模式 (Singleton Pattern):
- Ensures a class has only one instance and provides a global point of access to that instance.
工厂模式 (Factory Pattern):
- Defines an interface for creating an object, but lets subclasses alter the type of objects that will be created.
观察者模式 (Observer Pattern):
- Defines a dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.
命令模式 (Command Pattern):
- Encapsulates a request as an object, thereby allowing for parameterization and queuing of requests, and providing additional functionalities such as logging and support for undoable operations.
策略模式 (Strategy Pattern):
- Defines a family of algorithms, encapsulates each one, and makes them interchangeable. Strategy lets the algorithm vary independently from clients that use it.
适配器模式 (Adapter Pattern):
- Allows incompatible interfaces to work together. It wraps an interface around one of the existing classes.
装饰器模式 (Decorator Pattern):
- Attaches additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality.
以上的设计原则和设计模式是软件设计和开发过程中常用的几个概念,它们帮助开发人员编写出高质量、易维护的代码。
