Arrays vs Collections

Question

Collections is a separate framework which is designed to handle data structures easily so that you can focus more on the logic building part of your program.

Collections is an interface which is broken down into other interfaces-
1) Set
2) List
3) Queue
4) Deque

Collections provide various functions which make your data manipulation easy when compared to arrays.
