import java.util.*;
public class IsEmpty {
public static void main(String[] args) {
//Creating vector
Vector v = new Vector();
//Adding element to the vector
v.add("Rose");
v.add("India");
v.add("Rohini");
v.add("Girish");
//Creating Enumeration Interface
Enumeration e = v.elements();
System.out.print("Vector is : ");
while (e.hasMoreElements()) {
System.out.print(e.nextElement() + "\t");
}
//Tests if vector v has no components.
boolean b = v.isEmpty();
System.out.println("");
System.out.println("Vector is Empty : " + b);
//Creating another vector
Vector v1 = new Vector();
System.out.print("Vector is : ");
//Tests if vector v1 has no components.
boolean b1 = v1.isEmpty();
System.out.println("");
System.out.println("Vector is Empty : " + b1);
}
