SortedMap entrySet() method in Java with Examples Last Updated : 26 Nov, 2018 Comments Improve Suggest changes Like Article Like Report The entrySet() method of SortedMap interface in Java is used to create a set out of the same elements contained in the map. It basically returns a set view of the map or creates a new set and store the map elements into them. Syntax: SortedMap.entrySet() Parameters: The method does not take any parameter. Return Value: The method returns a set having same elements as the map. Below programs are used to illustrate the working of above method: Program 1: Using HashMap. Java // Java code to illustrate the entrySet() method import java.util.*; public class SortedMap_Demo { public static void main(String[] args) { // Creating an empty TreeMap SortedMap<String, Integer> sotree_map = new TreeMap<String, Integer>(); // Mapping int values to string keys sotree_map.put("Geeks", 10); sotree_map.put("4", 15); sotree_map.put("Geeks", 20); sotree_map.put("Welcomes", 25); sotree_map.put("You", 30); // Displaying the TreeMap System.out.println("Initial Mappings are: " + sotree_map); // Using entrySet() to get the set view System.out.println("The set is: " + sotree_map.entrySet()); } } Program 2: Java // Java code to illustrate the entrySet() method import java.util.*; public class SortedMap_Demo { public static void main(String[] args) { // Creating an empty TreeMap SortedMap<Integer, String> sotree_map = new TreeMap<Integer, String>(); // Mapping string values to int keys sotree_map.put(10, "Geeks"); sotree_map.put(15, "4"); sotree_map.put(20, "Geeks"); sotree_map.put(25, "Welcomes"); sotree_map.put(30, "You"); // Displaying the TreeMap System.out.println("Initial Mappings are: " + sotree_map); // Using entrySet() to get the set view System.out.println("The set is: " + sotree_map.entrySet()); } } Note: The same operation can be performed with any type of Mappings with variation and combination of different data types.
