In addition to collections, the framework defines several map interfaces and classes. Maps store key/value pairs. Although maps are not collections in the proper use of the term, but they are fully integrated w

This interface is a member of theJava Collections Framework. Implementation Requirements: The default method implementations (inherited or otherwise) do not apply any synchronization protocol. If aCollectionimplementation has a specific synchronization protocol, then it must override default implementations to...
A data structure is a collection of data organized in some fashion. The structure not only stores data but also supports operations for accessing and manipulating the data. The java.util package contains one of Java’s most powerful subsystems: The Collections Framework. The Collections Framework ...
Java集合类分为两大类:Collection和Map。为什么要这样分类呢? 先看Collection。Collection翻译为中文是”集合“的意思。学过数学都知道,集合是一类元素组成的集体,它的每一个单位元素都是单一的个体。我们可以把Collection看成是一个装着球的格子箱,箱里的每一个格子只能放一个球: ...
The Collections framework has always provided a number of so-called "bulk operations" as part of its API. These include methods that operate on entire collections, such ascontainsAll,addAll,removeAll, etc. Do not confuse those methods with the aggregate operations that were introduced in JDK 8....
