Java HashSet工作原理及实现 1. 概述 This class implements the Set interface, backed by a hash table (actually aHashMapinstance). It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. This class permi...

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 ...

Java LinkedHashSet class extends HashSet and implements Set interface. It is very very similar to HashSet class and offers the predictable iteration order.
Firstly we’ll look at theConcurrentHashMapclass that exposed the staticnewKeySet()method. Basically, this method returns an instance that respects thejava.util.Setinterface and allows the usage of standard methods likeadd(), contains(),etc. ...
