另一个很好的原因是链表非常适合高效的多线程实现。这样做的原因是，更改往往是局部的——只影响数据结构局部部分的插入和删除的一两个指针。所以，你可以让多个线程在同一个链表上工作。更重要的是，可以使用cas类型的操作创建无锁版本，并完全避免沉重的锁。

使用链表，迭代器还可以在进行修改时遍历列表。在修改没有冲突的乐观情况下，迭代器可以在没有争用的情况下继续。

对于数组，任何修改数组大小的更改都可能需要锁定数组的很大一部分，事实上，这是在整个数组上没有全局锁的情况下完成的，因此修改会停止全局事务。

Arrays make sense where the exact number of items will be known, and where searching by index makes sense. For example, if I wanted to store the exact state of my video output at a given moment without compression I would probably use an array of size [1024][768]. This will provide me with exactly what I need, and a list would be much, much slower to get the value of a given pixel. In places where an array does not make sense there are generally better data types than a list to deal with data effectively.

除了插入到列表中间更容易之外——从链表中间删除也比从数组中删除容易得多。

但坦率地说，我从未使用过链表。每当我需要快速插入和删除时，我也需要快速查找，所以我使用HashSet或Dictionary。

这里有一个快速的方法:移除物品更快。

While many of you have touched upon major adv./dis of linked list vs array, most of the comparisons are how one is better/ worse than the other.Eg. you can do random access in array but not possible in linked list and others. However, this is assuming link lists and array are going to be applied in a similar application. However a correct answer should be how link list would be preferred over array and vice-versa in a particular application deployment. Suppose you want to implement a dictionary application, what would you use ? Array : mmm it would allow easy retrieval through binary search and other search algo .. but lets think how link list can be better..Say you want to search "Blob" in dictionary. Would it make sense to have a link list of A->B->C->D---->Z and then each list element also pointing to an array or another list of all words starting with that letter ..

A -> B -> C -> ...Z
|    |    |
|    |    [Cat, Cave]
|    [Banana, Blob]
[Adam, Apple]

Now is the above approach better or a flat array of [Adam,Apple,Banana,Blob,Cat,Cave] ? Would it even be possible with array ? So a major advantage of link list is you can have an element not just pointing to the next element but also to some other link list/array/ heap/ or any other memory location. Array is a one flat contigous memory sliced into blocks size of the element it is going to store.. Link list on the other hand is a chunks of non-contigous memory units (can be any size and can store anything) and pointing to each other the way you want. Similarly lets say you are making a USB drive. Now would you like files to be saved as any array or as a link list ? I think you get the idea what I am pointing to :)

当集合不断增加和减少时，链表尤其有用。例如，很难想象尝试使用数组实现一个Queue(添加到末尾，从前面删除)—您将花费所有时间向下移动内容。另一方面，对于链表来说，这是微不足道的。
