Yep means, i agree....
it just makes you look incompetent.
....For you only....
I've learn stack in C and Assembly.
in C, nice and helpful to implement...
in Assembly, i always use stack implementation
(if all general registers are full)
But for Java? i never use that on my application(just on exercises).
What for?
Can you show us a serious application that uses a stack? And that application is fully dependent on a stack implementation?
Maybe stack in java will be useful if you will design a new higher level language compiler using java.
