Vector hashCode() Method in Java

Last Updated : 17 Aug, 2018

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
