Let us discuss all the LinkedHashMap methods one by one with Examples in Java. 1. void clear() This method as the name suggests removes all the entries in the LinkedHashMap, as shown in the following program import java.util.LinkedHashMap; import java.util.Map; public class LinkedHashMap...
In Java, LinkedHashMap is an implementation of linkedlist from the interface Map. It is similar to HashMap, where an extra feature is included that maintains the order of elements that are being inserted into it. Even though HashMap provides quick insertion, deletion, and search, element inser...

LinkedHashMapin Java is used to store key-value pairs very similar toHashMapclass. Difference is that LinkedHashMap maintains the order of elements inserted into it while HashMap is unordered. In this Java collection tutorial, we will learn about LinkedHashMap class, it’s methods, usecases ...
Methods of Java LinkedHashMap class ADVERTISEMENT MethodDescription V get(Object key)It returns the value to which the specified key is mapped. void clear()It removes all the key-value pairs from a map. boolean containsValue(Object value)It returns true if the map maps one or more keys to...
Java集合之LinkedHashMap源码分析 概述HashMap是无序的, 即put的顺序与遍历顺序不保证一样. LinkedHashMap是HashMap的一个子类, 它通过重写父类的相关方法, 实现自己的功能. 它保留插入的顺序. 如果需要输出和输入顺序相同时, 就选用此类. LinkedHashMap原理 LinkedHashMap是如何保证输入输出顺序的呢? LinkedHash...
