import java.util.HashMap; public class HashMapExample { public static void main(String[] args) { //initialize a new HashMap object HashMapBrief Description: The code examples illustrate the use of the hashCode() method in the java.util.HashMap class to retrieve the hash code value for a key in a HashMap object. The first example uses the key "apple" and the second example uses the key "banana". The hash code value is printed to the console. Package Library: java.utilmap = new HashMap<>(); //add key-value pairs to the HashMap map.put("apple", 50); map.put("banana", 25); map.put("orange", 75); //get the hash code value for the key "banana" int hashCode = map.get("banana").hashCode(); System.out.println("Hash code value of the key 'banana': " + hashCode); } }
