The java.util.vector.hashCode() method in Java is used to get the hashcode value of this vector.
Syntax:
Vector.hashCode()
Parameters: The method does not take any parameter.
Return Value: The method returns hash code value of this Vector which is of Integer type.
Below programs illustrate the Java.util.Vector.hashCode() method:
Program 1: Vector with string elements.
// Java code to illustrate hashCode() import java.util.*; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<String> vec_tor = new Vector<String>(); // Use add() method to add elements into the Vector vec_tor.add("Welcome"); vec_tor.add("To"); vec_tor.add("Geeks"); vec_tor.add("4"); vec_tor.add("Geeks"); // Displaying the Vector System.out.println("Vector: " + vec_tor); // Displaying the hashCode value of Vector System.out.println("The hashCode value is: " + vec_tor.hashCode()); } } |
Output:
Vector: [Welcome, To, Geeks, 4, Geeks] The hashCode value is: -878886256
Program 2: Vector with integer elements.
// Java code to illustrate hashCode() import java.util.*; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<Integer> vec_tor = new Vector<Integer>(); // Use add() method to add elements into the Vector vec_tor.add(10); vec_tor.add(20); vec_tor.add(30); vec_tor.add(40); vec_tor.add(50); // Displaying the Vector System.out.println("Vector: " + vec_tor); // Displaying the hashCode value of Vector System.out.println("The hashCode value is: " + vec_tor.hashCode()); } } |
Output:
Vector: [10, 20, 30, 40, 50] The hashCode value is: 38490301
