ACollectionrepresents a group of objects known as its elements. TheCollectioninterface is used to pass around collections of objects where maximum generality is desired. For example, by convention all general-purpose collection implementations have a constructor that takes aCollectionargument. This constru...
interface:所有的接口 implementation:所有的实现 algorithm:static的算法 接口(interface): java collection中的接口可以分为两块,java.util.Collection 和 java.util.Map,两块的一些常用的类可以由下图概况。图中需要注意的一点是Deque实际上是Queue的subinterface java.util.Collection: java.util.Set java.util.Sorted...
3.1 Collection Interface接口 这是集合层次结构的根。集合表示一组称为其元素的对象。Java平台不提供此接口的任何直接实现。 该接口有方法来告诉你有多少元素集合中(size,isEmpty),检查给定对象是否是集合(中contains),添加和从集合中删除元素(add,remove),并在提供的迭代器集合(iterator)。 Collection接口还提供批量...

Collection— the root of the collection hierarchy. A collection represents a group of objects known as itselements. TheCollectioninterface is the least common denominator that all collections implement and is used to pass collections around and to manipulate them when maximum generality is desired. So...

https://docs.oracle.com/javase/8/docs/technotes/guides/collections/overview.html 原文内容也一并附加在本文最后. 简介: Java平台包含一个集合框架。 集合是表示一组对象的对象(如经典的Vector类)。 集合框架是用于表示和操作集合的统一体系结构,使集合可以独立于实现细节而被操纵。
