SortedMap hashCode() method in Java with Examples Last Updated : 30 Sep, 2019 Comments Improve Suggest changes Like Article Like Report The hashCode() method of SortedMap interface in Java is used to generate a hashCode for the given map containing key and values. Syntax: int hashCode() Parameters: This method has no argument. Returns: This method returns the hashCode value for the given map. Note: The hashCode() method in SortedMap is inherited from the Map interface in Java. Below programs show the implementation of int hashCode() method. Program 1: Java // Java code to show the implementation of // hashCode() method in SortedMap interface import java.util.*; public class GfG { // Driver code public static void main(String[] args) { // Initializing a SortedMap // of type TreeMap SortedMap<Integer, String> map = new TreeMap<>(); map.put(1, "One"); map.put(3, "Three"); map.put(5, "Five"); map.put(7, "Seven"); map.put(9, "Ninde"); System.out.println(map); int hash = map.hashCode(); System.out.println(hash); } } Output: {1=One, 3=Three, 5=Five, 7=Seven, 9=Ninde} 238105666 Program 2: Below is the code to show implementation of hashCode().
