As I finished learning about Collection Framework, there is this question that i couldn't find an answer for.
When to use this framework? Only when i'm manipulating data that is stored temporarely?
For example, i wrote an address book program that manipulates the data using the CF. But once the program stops running, i use all the data. I know i could use a database or a file, but once i use either of these, does it mean i won't use the CF anymore?
I'm a bit confused.
Thanks for your replies guys in advance
