1. Set Interface Set interface extends Collection interface. In a set, no duplicates are allowed. Every element in a set must be unique. You can simply add elements to a set, and duplicates will be removed automatically. 理解:Set中不包含重复元素.Set有三种实现方式:HashSet,TreeSet和LinkedHash...
1、通过下面的代码可以看出LinkedHashSet是HashSet的子类,其底层是通过LinkedHashMap来实现数据的存储和排序的 。 publicclassLinkedHashSet<E>extendsHashSet<E>implementsSet<E>, Cloneable, java.io.Serializable {privatestaticfinallongserialVersionUID = -2851667679971038690L;//调用父类的构造函数,通过HashSet的构...
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 ...

The LinkedHashSet class of the Java collections framework provides functionalities of both the hashtable and the linked list data structure. It implements the Set interface. Elements of LinkedHashSet are stored in hash tables similar to HashSet. However, linked hash sets maintain a doubly-linked ...
Java LinkedHashSet class extends HashSet and implements Set interface. It is very very similar to HashSet class and offers the predictable iteration order.
// Java程序示例 // clear()方法 // 用于字符串值 import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // 创建LinkedHashSet<Integer>对象 LinkedHashSet<String> linkset = new LinkedHashSet<String>(); // 填充哈希集 linkset.add("A");...
