Java集合我应该用什么？ [英] What Java Collection should I use?

问题描述

在这个问题<一href="http://stackoverflow.com/questions/10699265/how-can-i-efficiently-select-a-standard-library-container-in-c11">How我可以有效地选择在C ++ 11标准库容器？是一个方便的流程图选择C ++集合时使用。

In this question How can I efficiently select a Standard Library container in C++11? is a handy flow chart to use when choosing C++ collections.

我认为这是人谁不知道哪个集合，他们应该使用，所以我试图找到一个类似的流程图Java和不能够这样做一个有用的资源。

I thought that this was a useful resource for people who are not sure which collection they should be using so I tried to find a similar flow chart for Java and was not able to do so.

什么是可以帮助人们选择正确的集合在Java编程时使用的资源和备忘单？人们怎么知道他们应该用什么名单，设置和地图的实现？

What resources and "cheat sheets" are available to help people choose the right Collection to use when programming in Java? How do people know what List, Set and Map implementations they should use?

推荐答案

因为我无法找到任何东西，我决定做一个自己。

Since I couldn't find anything I decided to make one myself.

该流程图并不试图掩盖的东西一样同步访问，线程安全等或传统的收藏品，但它确实涵盖了3个标准设置 S，3个标准地图和2个标准列表秒。

This flow chart does not try and cover things like synchronized access, thread safety etc or the legacy collections, but it does cover the 3 standard Sets, 3 standard Maps and 2 standard Lists.

主要其他有用的参考人可能是从Oracle文档描述每个<一个下页href="http://docs.oracle.com/javase/tutorial/collections/implementations/index.html">Collection.

The main other useful reference to people is probably the following page from the oracle documentation which describes each Collection.

还有时使用的详细讨论的HashSet 或 TreeSet的在这里： VS的Hashset TreeSet的

There is a detailed discussion of when to use HashSet or TreeSet here: Hashset vs Treeset
