import java.util.Vector;

/*
 *  Example of firstElement(), lastElement() method. 
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<Integer> vector = new Vector<Integer>();

        vector.add(10);
        vector.add(20);
        vector.add(30);
        vector.add(40);
        vector.add(50);

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

        /*
         * Returns the first component (the item at index 0) of this vector.
         */

        Integer firstElement = vector.firstElement();
        System.out.println("firstElement : " + firstElement);

        /*
         * Returns the last component of the vector.
         */
        Integer lastElement = vector.lastElement();
        System.out.println("lastElement : " + lastElement);

    }
}

Output

vector  : [10, 20, 30, 40, 50]

firstElement : 10
lastElement : 50
