1. 概述 Hash table and linked list implementation of the Set interface, with predictable iteration order. This implementation differs from HashSet in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is the order in ...
Note that this implementation is not synchronized.If multiple threads access a hash set concurrently, and at least one of the threads modifies the set, itmustbe synchronized externally. This is typically accomplished by synchronizing on some object that naturally encapsulates the set. If no such ob...

spliteratorin interfaceCollection<E> Specified by: spliteratorin interfaceSet<E> Overrides: spliteratorin classHashSet<E> Implementation Note: The implementation creates alate-bindingspliterator from the set'sIterator. The spliterator inherits thefail-fastproperties of the set's iterator. The createdSplit...
As the name of the classsuggests, the sorting is accomplished by a tree data structure(The current implementation uses a red-black tree). Every time an element is added to a tree, it is placed into its proper sorting position. Therefore, the iterator always visits the elements in sorted or...
spliterator在类HashSet<E> Implementation Note: 该实现从集合Iterator创建了一个late-binding分裂Iterator。 spliterator继承了set迭代器的fail-fast属性。 创建的Spliterator另外报告Spliterator.SUBSIZED。 结果 Spliterator超过此集合中的元素 从以下版本开始: 1.8 跳过...
