Operator Overloading: 允许程序员重新定义内置运算符的行为,以便它们能够用于自定义类型。 相关优势 类型安全:enum class提供了更强的类型检查,避免了传统enum可能导致的类型混淆问题。 作用域控制: 枚举值的作用域被限制在枚举类型内部,减少了命名冲突的可能性。
Prefer enums over strings or integers as option markers. Enhanced enums support constructors, properties, methods, operator overloading, interfaces, mixins and generics. Enums must haveconstconstructors. The enum values are instances of the enum class. ...

java构造函数调用技巧Java是一个纯的面向对象的程序设计语言,它继承了 C++ 语言面向对象技术的核心,Java舍弃了C ++语言中容易引起错误的指针(以引用取代)、运算符重载(operator overloading)、多重继承(以接口取代)等特性,增加了垃圾回收器功能用于回收不再被引用的对象所占据的内存空间,使得程序员不用再为内存管理...
