Hi Laur, What is the purpose of having an AbstractClass for each Collection Interface, for eg, we have AbstractList, AbstractSet and so on.

Hi Laur,
Why doesn't ArrayList class use something like:
E [] elementData
Under the hood?

Sir I retrieved records from DB and hold it in the list but no of the records is more than 600 to 800 hundreds so list is responding after 15 to 20 seconds so can you provide me solution or any alternative to solve this problem??
