store list of names in a variable

hi ....how to store list of names in a variable...show me a sample code

[Balasubramanian Chandrasekaran]

Hi preethi Ayyappan,

I usually do it this way,the code goes like this

1. Import java utilities

  import java.util.*;  

2. Declare a Vector class object

   Vector<String> newvct = new Vector<String>(); 

3. Insert the name which you want to store

  newvct.add("James");
newvct.add("Bond");
newvct.add("John");  

4. Declare a Enumerator

  Enumeration e = newvct.elements();  

5. Then read values from the enumaration

   
while(e.hasMoreElements())
        {
        System.out.println ("The Value is:" + (String)e.nextElement());
        }

thanks bala....

You would usually be better off using java.util.ArrayList than Vector. And you are also better using the name of the interface List to declare the list rather than the class name.
And don't use variable names like newvct; call them something which a reader can understand.

[Campbell Ritchie]

And to get the elements back use the for-each loop or an Iterator rather than an Enumeration.

Thanks Campbell Ritchie.
I figured out the difference between Vector and ArrayList

Only too pleased to help. And well done tracking down the difference, but the posts on that Sun forum are much harder to understand than anything on JavaRanch

Hi Campbell,

After reading the differences between Vector class and ArrayList i can understand that it differs in the way of synchronization.
Synchronization is the only bottle neck in using Vector when compared to ArrayList or else more?

It's a legacy List implementation - I would strongly suggest not using it for new code. I'd suggest using ArrayList as your "default" list implementation, and use other structures when it makes sense.
