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
