LinkedList is implemented with a double-linked list; ArrayList is implemented with a dynamically resizing array. 所以基本的区别于list和array的区别很像,就是for random access, ArrayList is better; for adding and deleting, LinkedList is better. LinkedList takes more space since it has to store both ...

List保持插入顺序。 Set不维护任何插入顺序。 Map 也不保持任何插入顺序。 可以添加任何数量的 null 值。 但在Set中只有一个 null 值。 Map 最多允许一个空键和任意数量的空值。 List的实现类有:ArrayList, LinkedList。 Set的实现类有:HashSet, LinkedHashSet, 和TreeSet。 Map 的实现类有HashMap、HashTable...

In this guide, you will learn difference between ArrayList and LinkedList in Java. ArrayList and LinkedList both implements List interface and their methods and results are almost identical. However there are few differences between them which make one b
