Vector hashCode() Method in Java (original) (raw)

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.

import java.util.*;

public class VectorDemo {

`` public static void main(String args[])

`` {

`` Vector<String> vec_tor = new Vector<String>();

`` vec_tor.add( "Welcome" );

`` vec_tor.add( "To" );

`` vec_tor.add( "Geeks" );

`` vec_tor.add( "4" );

`` vec_tor.add( "Geeks" );

`` System.out.println( "Vector: " + vec_tor);

`` 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.

import java.util.*;

public class VectorDemo {

`` public static void main(String args[])

`` {

`` Vector<Integer> vec_tor = new Vector<Integer>();

`` vec_tor.add( 10 );

`` vec_tor.add( 20 );

`` vec_tor.add( 30 );

`` vec_tor.add( 40 );

`` vec_tor.add( 50 );

`` System.out.println( "Vector: " + vec_tor);

`` System.out.println( "The hashCode value is: "

`` + vec_tor.hashCode());

`` }

}

Output:

Vector: [10, 20, 30, 40, 50] The hashCode value is: 38490301
