LinkedHashMap get() Method in Java with Examples Last Updated : 17 Nov, 2021 Comments Improve Suggest changes Like Article Like Report In Java, get() method of LinkedHashMap class is used to retrieve or fetch the value mapped by a particular key mentioned in the parameter. It returns NULL when the map contains no such mapping for the key. --> java.util Package --> LinkedHashMap Class --> get() Method Syntax: Linked_Hash_Map.get(Object key_element) Parameter: One parameter key_element of object type and refers to the key whose associated value is supposed to be fetched. Return Type: Value associated with the key_element in the parameter. Example 1: Mapping String Values to Integer Keys. Java // Java Program to illustrate get() method // of LinkedHashMap // Mapping String Values to Integer Keys // Importing required classes import java.util.*; // Main class public class GFG { // Main driver method public static void main(String[] args) { // Creating an empty HashMap LinkedHashMap<Integer, String> li_hash_map = new LinkedHashMap<Integer, String>(); // Mapping string values to int keys // using put() method li_hash_map.put(10, "Geeks"); li_hash_map.put(15, "4"); li_hash_map.put(20, "Geeks"); li_hash_map.put(25, "Welcomes"); li_hash_map.put(30, "You"); // Printing all elements of LinkedHashMap System.out.println("Initial Mappings are: " + li_hash_map); // Getting the value of 25 System.out.println("The Value is: " + li_hash_map.get(25)); // Getting the value of 10 System.out.println("The Value is: " + li_hash_map.get(10)); } } Output: Initial Mappings are: {10=Geeks, 15=4, 20=Geeks, 25=Welcomes, 30=You} The Value is: Welcomes The Value is: Geeks Example 2: Mapping Integer Values to String Keys Java // Java Program to Illustrate get() method // Mapping Integer Values to String Keys // Importing required classes import java.util.*; // Main class public class Linked_Hash_Map_Demo { // Main driver method public static void main(String[] args) { // Creating an empty LinkedHashMap LinkedHashMap<String, Integer> li_hash_map = new LinkedHashMap<String, Integer>(); // Mapping int values to string keys // using put() method li_hash_map.put("Geeks", 10); li_hash_map.put("4", 15); li_hash_map.put("Geeks", 20); li_hash_map.put("Welcomes", 25); li_hash_map.put("You", 30); // Printing all elements of LinkedHashMap System.out.println("Initial Mappings are: " + li_hash_map); // Getting the value of "Geeks" System.out.println("The Value is: " + li_hash_map.get("Geeks")); // Getting the value of "You" System.out.println("The Value is: " + li_hash_map.get("You")); } } Output: Initial Mappings are: {Geeks=20, 4=15, Welcomes=25, You=30} The Value is: 20 The Value is: 30 Note: The same operation can be performed with any type of Mappings with variation and combination of different data types.

But these hashing function may lead to collision that is two or more keys are mapped to same value. Chain hashing avoids collision.
