VectorExample.java
import java.util.Vector;

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

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

        /*
         * Tests if this vector has no components.
         */

        boolean isEmpty = vector.isEmpty();

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

        vector.add(10);
        vector.add(20);

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

        /*
         * Tests if this vector has no components.
         */

        isEmpty = vector.isEmpty();

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

    }
}

Output
vector  : []
isEmpty  : true

vector  : [10, 20]
isEmpty  : false
