Article Introduction：LinkedHashMap is a general class of JavaCollectionFramework, which implements the Map interface. As the name suggests, it is a subclass of HashMap class and uses a bidirectional LinkedList to store entries in insertion order. It maintains key-value pairs of entries. Key is an object used to obtain and receive the value associated with it. So we can use this key along with the "get()" method to get all the values ​​from the LinkedHashMap. The purpose of this article is to explain the different methods of printing all the values ​​of a LinkedHashMap. Java Program to Get All Values ​​of LinkedHashMap Before jumping directly to the example program, let’s first understand

Article Introduction：The difference between HashMap and LinkedHashMap in Java is: HashMap is the most commonly used Map, which stores data according to the HashCode value of the key; LinkedHashMap is a subclass of HashMap, which saves the insertion order of records.

Article Introduction：LinkedHashMap is a general class used to implement the Map interface. Furthermore, it is a subclass of HashMap class, so it can use all methods of HashMap class and perform similar operations. Java provides various methods to sort LinkedHashMap, through this article we will learn how to create it using Comparable interface and sort it by its value. Program to Sort LinkedHashMap by Value Before jumping directly to the sorting program, let us look at a few concepts - LinkedHashMap As we discussed earlier, the LinkedHashMap class extends the HashMap class to implement the Map interface. it dimension
