增长见闻,留下美好!

亲爱的您,这里是LearningYard新学苑。

今天小编为大家带来“悦见新知(9):面向对象编程入门(竞赛篇)”。

欢迎您的访问!

Share interest, spread happiness,

increase knowledge, and leave beautiful.

Dear, this is the LearingYard New Academy!

Today, the editor brings the “New insights (9): introduction to object-oriented programming (competition)”

Welcome to visit!

一、思维导图(Mind Map)

二、核心知识点(Core Knowledge Points)

1. 类与对象:从现实到代码(Class and Object: From Reality to Code)

创建选手类(Create a player class)

2. 封装:保护数据,提供接口(Encapsulation: Protect Data and Provide Interfaces)

私有属性与公有方法(Private attributes and public methods)

3. 继承:复用与扩展(Inheritance: Reuse and Extension)

创建派生类(Create derived classes)

4. 多态:同一接口,不同实现(Polymorphism: Same Interface, Different Implementations)

5. 实战:竞赛管理系统(Practical Application: Competition Management System)

三、总结(Summary)

类与对象:类是蓝图,对象是实例。

Class and Object: A class is a blueprint, and an object is an instance.

1. 封装:私有属性(__开头)保护数据,通过方法访问。

1. Encapsulation: Private attributes (prefixed with __) protect data, which is accessed through methods.

2. 继承:子类复用父类代码,可重写方法。

2. Inheritance: A subclass reuses the code of a parent class and can override methods.

3. 多态:不同对象调用相同方法,产生不同行为。

3. Polymorphism: Different objects call the same method but produce different behaviors.
