Java Collections - How to Create Vector

Published April 04, 2022

To create a Java vector, you simply need to import the Java.util.Vector and then create a Vector using the syntax below:

Vector<Type> vector = new Vector<>()


where the Type of the Vectors can either be a string or an integer.

Vector Methods 

  • add(element)- adds elements to a vector

  • add(index, element)- adds elements  to a specific position 

  • addAll(vector)- adds elements of the vector to another vector

  • get(index)-returns elements that the index has specified

  • iterator()- returns an iterator object to access vector elements sequentially.

  • Remove(index)- removes  the specified element

  • removesAll()- all elements are removed

  • clear()- clears all elements


Create Simple Vector Example in Java

import java.util.Vector;

public class VectorExample {

    public static void main(String[] args) {

        Vector<String> fish= new Vector<>();

        // Using the add() method



        // Using index number

        fish.add(2, "mudgfish");

        System.out.println("Vector: " + fish);

        // Using addAll()

        Vector<String> amphibians = new Vector<>();



        System.out.println("New Vector: " + amphibians);








Vector: [Shark,Dolphines,mudgfish]

New Vector: [Lizards.Lizards]
