Hi,

What is the need of Collection framework in Java since all the data operations(sorting/adding/deleting) are possible with Arrays and moreover array is suitable for memory consumption and performance is also better compared with Collections.

Can anyone point me a real time data oriented example which shows the difference in both(array/Collections) of these implementations.

Thx
