Which would be better List iterator or accessing through index?

[deepuhassan]

Hi All,
i have doubt regarding the usage of iterator.We stores a list of values in a arraylist.Inorder to access it right now we are using list iterator and taking the values and comparing the values with the existing key. If there is a match with the key,then we are using that particular value.

The point is the arraylist contains dynamic data and the data might be in several thousands,but some how I could able to get the index of the value which exactly matches with key.

I compared both approach and I couldn't find any problem with it.

Since it is web application when the load increases,the performance is bit slow.

So I need a resolution for this..

Please help...

Do you really need to use iterator?

If you need to know the index, you can go to each element with a simple for.
