One over Another?

[Gregg Bolinger]

Could someone tell me if one way is better than the other.
Way # 1
-------

import java.util.*;
class Program1 {
    
    static String s = "0123456789";
static Vector v = new Vector();   
    static String parser;
    static String ss;
    
    
    
    public static void main(String[] args) {
    
    for (int a = 0; a < s.length(); a++) {
    parser = s.substring(a, a+1);
    v.add(parser);
    
    }    
for (Enumeration e = v.elements() ; e.hasMoreElements()  [img]http://www.javaranch.com/ubb/wink.gif[/img] {
         
         
         System.out.println(e.nextElement());
        }
    
    
    }
}

Way # 2
--------

import java.util.*;
class Program1 {
    
    static String s = "0123456789";
static Vector v = new Vector();   
    static String parser;
    static String ss;
    
    
    
    public static void main(String[] args) {
    
    for (int a = 0; a < s.length(); a++) {
    parser = s.substring(a, a+1);
    v.add(parser);
    
    }    
for (int b = 0; b < v.capacity(); b++) {
System.out.println(v.get(b));
}    
    
    }
}

Thanks

What my question was, what does Enumeration do for me that is different than just accessing the object in the vector??

Enumerations abstract the retrieving so you don't need to know the specific method for a Vector. Eg you don't need to know that get() is a method in Vector, you just use an enumeration. The advantage is that enumerations provide a consistent means of retrieval for objects that support them, whereas the get() method of Vector might not exist for another object.
I hope I've got that right. Does that make sense?

Made sense to me.

[Gregg Bolinger]

Ahhhhh! I see. That's nice. Sun just thought of everything, didn't they. Thank you very much!!

Well, the idea has been around a lot longer than Sun or Java!

Hi Gregg,
why would you use v.capacity() as against v.size()?
I thought size gives the number of elements in the vector and capacity is the length of the internal array and can be more than number of elements currently present.

Programming error on my part. Thanks for the debug.
