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.

Java `

// Java code to illustrate hashCode() import java.util.*;

public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector vec_tor = new Vector();

    // 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 `

// Java code to illustrate hashCode() import java.util.*;

public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector vec_tor = new Vector();

    // 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
