All collections frameworks contain the following −Interfaces − These are abstract data types that represent collections. Interfaces allow collections to be manipulated independently of the details of their representation. In object-oriented languages, interfaces generally form a hierarchy. Implementations...
The Java Collections Framework in whole picture 纵观Java Collections Framework的历史 Collections frameworks这种做法并不是Java独创,在Java之前其他语言就有类似的实现,如C++的STL(Standard Template Library),但STL的各种实现多达上百个,非常复杂。Java Collections Framework借鉴了前人的一些做法,同时也尝试做了一些改进...
Java collections framework is a unified architecture for representing and manipulating collections. All collections frameworks contain the following: Interfaces: These are abstract data types that represent collections. Interfaces allow collections to be manipulated independently of the details of their ...

In this quick tutorial, we’ll explore different ways of combining collections in Java. We’ll explore various approaches using Java and external frameworks like Guava, Apache, etc. For the introduction to Collections, have a look at this series here. 2. External Libraries to Work With Collecti...
Any implementation of a collection, whether it is one provided by the Java Collections Framework or one of your own creations, will support one of these interfaces. Because the Collections framework is regular and consistent, you will learn a large portion of the frameworks simply by learning ...
Important Methods Used by the Java Iterator: 1) boolean hasNext(): this method returns true when there is another element to be traversed in the collection. 2) Object next(): It provides the next object to be traversed. This method throws an exception if there are no more elements to be...

Library (STL) and Smalltalk's collection hierarchy. Historically, collections frameworks have been quite complex, which gave them a reputation for having a steep learning curve. We believe that the Java Collections Framework breaks with this tradition, as you will learn for yourself in this chapter...
