[@Anilkumar-ec8sj]

clearly explained tutorials Durga sir , but error in notes 1. for loop

[@TravelWorld1]

Good video

[@myjntustudy3431]

Anna , I am very Happy with ur explanation :) I have a doubt :-
why are you using Integer I = (Integer)itr.next(); ? Can't we use int i = itr.next(); //// or can't we use Integer I = Integer.parseInt(itr.next); ??

[@moududhassan3026]

We can convert any collection to vector, then we can use Enumeration :)

[@hellosagar]

Fan of accent

[@rajeevranjan185]

For array list we can use loop to perform any operations on elements. What is diff between using collection cursor and basic looping??

[@DurgaSoftwareSolutions]

Hello Rajeev.
Plz contact our online team [e-mail] or call us on this number [phone], 7207212427/28

[@pal0106]

what happens to the pointer(or cursor) after the remove operation? where is it pointing?

[@SpiritualMeP]

You are a very good teacher. Just a humble suggestion. If you are considering global audience please try to improve the english accent (yours has a heavy (tamil ?) accent)

[@TravelWorld1]

i agree

[@arun0p0s]

that true... his slang dominated by Telugu..... eg reading iterator as etterator is kind of things he should improve...

[@VishalTheK]

Actually this makes him unique. He has defined his protocol naturally.

[@chiragvasani7231]

But Enumeration is working with ArrayList and LinkedList which are not from legacy classes..

[@prasannaprathiba]

From itr.remove(); how it's affected to the AyyaList object( l ) ?. we are doing change to the ' itr' reference

[@venkatbole541]

Hi..Videos are good but I have doubt over one statement u said during the lecture..
Disadvantage of Enumerator : "Enumerator supports legacy classes only". is this really comes under disadv ?? Can we list that in disadv??. When they developed later versions of java API, they could have thought that this enumeration was no longer useful for all collection classes due lack of functionalities like remove and all other stuff and decided to create separate interface called Iterator with all new name and functions.

[@bharathraj435]

sir,i had a doubt. Iterator itr = new iterator() here iterator is a method then how can a method contains other methods like hasnext(), next(), remove(). how can we create a object for a method. i cant understand the statement Iterator itr = new iterator().please clarify my doubt.

[@missiontechdk6064]

SIr i am getting "ConcurrentModificationException" in this example.

[@TA0992]

Itr point to 0, wouldnt I be initially pointing to 1? Since I = itr .next()

[@themrambusher]

sir i want to ask you that why are you using Integer I = (Integer)itr.next(); ? Can't we use int i = itr.next(); because next method returns Object type and Integer comes under Object so it will automatically type caste Object into Integer and then by unboxing it will convert it into int?? please sir clarify i'm a little bit confused
