ReadHow to add elements to a Java vector using index
Vector is a good replacement of array in Java if you want to add elements dynamically. We can add elements dynamically to a vector and it will increase its size, unlike arrays. Previously we have learned different examples of vectors like [how to create vectors](https://www.codevscolor.com/java-print-vector-contents), how to [add elements to a vector](https://www.codevscolor.com/add-elements-to-java-vector-using-index) and how to [clear a vector](https://www.codevscolor.com/how-to-clear-vector-in-java). In this tutorial, we will learn how to add elements to a vector in a specific position, i.e. using index numbers.
