Java面向对象多态性(七) 面向对象多态性 1、多态性的体现: 方法的重载和重写对象的多态性 2、对象的多态性 向上转型:程序会自动完成 父类 父类对象 = 子类实例 向下转型:强制类型转换 子类 子类对象 = (子类)父类实例 向上转型: 向下转型: 面向对象多态性的应用面向对象instanceof关键字 面向对象抽象类应用面向对象接口的使用 Java继承(1) 继承概述面向
Removes all but the first element in every consecutive group of equivalent elements, where two elements*iand*jare considered equivalent ifp(*i, *j)is true. The relative order of elements that are not removed is unchanged, and iterators to elements that are not removed remain valid. This funct...
