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。

types of collections allow duplicate elements, and others do not. Some are ordered and others are unordered. The Java platform doesn't provide any direct implementations of this interface but provides implementations of more specific subinterfaces, such asSetandList. Also seeThe Collection Interface...
The Java Collections Framework consists of: Collection interfaces: Represent different types of collections, such as sets, lists, and maps. These interfaces form the basis of the framework. General-purpose implementations: Primary implementations of the collection interfaces. ...
另外与Collections框架联系非常紧密的就是Iterator接口,它能够提供泛化的标准的访问遍历collections 对象元素的方法。另外在jdk8中新加入了Spliterator能够并行的进行迭代访问。 第一部分: Collections框架接口(THE COLLECTION INTERFACES) Collections框架定义了几个核心的借口,这个section给了一些总览。下面是核心接口的列表以及...

4. What is the benefit of Wrapper Class? Wrapper classes are used for the conversion of primitive data types to objects. In other words, wrapper classes wrap primitive types into objects. Wrapper classes are used when certain Java features like Collections only expect objects and not primitive ...
List<Integer>are different types, but they are implemented with the same code. Two kinds of Java code can be generic: types, such as the collection classes and interfaces; and methods, such as the static methods in the utility classjava.util.Collections. Let’s look at each of these in ...
