    import java.util.*;
    class Enum
    {
        public static void main(String args[])
        {
            Vector v=new Vector();
            v.add(args[0]);
            v.add(args[1]);
            v.add(args[2]);
            v.add(args[3]);
            v.add(args[4]);
            Enumeration e=v.elements();
            System.out.println("BEFORE SORTING : ");
            while(e.hasMoreElements())
            {
                System.out.println(e.nextElement());
            }

            Collections.sort(v);
            Enumeration e1=v.elements();
            System.out.println("After SORTING : ");
            while(e1.hasMoreElements())
            {
                System.out.println(e1.nextElement());
            }
        }
    }
BEFORE SORTING :
f
t
y
e
i
After SORTING :
e
f
i
t
y
