Vector class is in java.util package of java. Vector is dynamic array which can grow automatically according to the required need. Vector does not require any fix dimension like String array and int array. Vector contains many useful methods. To add element in Vector, we can use add() method of vector class. To add elements at fix position, we have to use add(index, object) method.

To get value from Vector, Vector provides get() method and Vector size() method. Size() method returns total number of elements in Vector.

Vector is synchronized, ArrayList is not...

Code:

import java.util.Vector;

public class VectorExample {

    public static void main(String[] args) {

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

        //    <E> Element type of Vector e.g. String, Integer, Object ...

        // add vector elements
        vc.add("Vector Object 1");
        vc.add("Vector Object 2");
        vc.add("Vector Object 3");
        vc.add("Vector Object 4");
        vc.add("Vector Object 5");

        // add vector element at index
        vc.add(3, "Element at fix position");

        // vc.size() inform number of elements in Vector
        System.out.println("Vector Size :"+vc.size());

        // get elements of Vector 
        for(int i=0;i<vc.size();i++)
        {
            System.out.println("Vector Element "+i+" :"+vc.get(i));
        }
    }
}
