1.Object-Oriented Programming(OOP:面向对象编程) 1.An object has a unique identity, states, and behaviors.属性与行为 2.Objects can interact with each other for computing tasks.对象之间的交互 用开车来类比 step1:declaration 1.Class: when programming in Java, we begin by declaring a program uni...
5. Encapsulation Encapsulation is hiding the state or internal representation of an object from the consumer of an API and providing publicly accessible methods bound to the object for read-write access. This allows for hiding specific information and controlling access to internal implementation. For ...
八.匿名对象(Anonymous Object) 1匿名对象是对象的简化形式2匿名对象两种使用情况31.对象方法仅进行一次调用时,多次调用不适合42.匿名对象可以作为实际参数进行传递5使用匿名对象的好处61.简化写法,不必定义变量接住对象引用72.对象用完之后就变成垃圾内存,可以被垃圾回收器回收 14151617 18222324...
