Why Iterator is better than Enumeration

i was reading one book......... in one example on Enumeration , it was written that as Enumeration is not good for new code........ use Iterator.
Both of them work in same manner........ so can anyone tell me why ?

Hello,
You can refer to previous thread..

"Vijay" we have told you multiple times to change your display name to meet the JavaRanch naming policy. If you don't change it to be your real first and last names, I will have to suspend your account.

Hi Megha, I think I am going to move this to the Java In General (Beginner) forum because your question isn't really about J2ME Mobile Applications.

Thanks

Mark
