import java.util.Vector;

/*
 * Example of Vector(int initialCapacity, int capacityIncrement) constructor.
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<String> vector = new Vector<String>(5, 2);
        vector.add("Dave");
        vector.add("Peter");
        vector.add("Phil");
        vector.add("Rohit");
        vector.add("Virat");

        System.out.println("vector : " + vector);
        System.out.println("vector size: " + vector.size());
        System.out.println("vector capacity: " + vector.capacity() + "\n");

        vector.add("Raj");

        System.out.println("vector : " + vector);
        System.out.println("vector size: " + vector.size());
        System.out.println("vector capacity: " + vector.capacity() + "\n");

    }
}

Output

vector : [Dave, Peter, Phil, Rohit, Virat]
vector size: 5
vector capacity: 5

vector : [Dave, Peter, Phil, Rohit, Virat, Raj]
vector size: 6
vector capacity: 7
