java - How expensive is a static ArrayList? -


let's have abstract class menu , 3 subclasses mexicanmenu, finnishmenu, japanesemenu.

is more expensive having each kind of menu static arraylist<string> menu or non-static one?

what pro , cons of using static menu against using "instance" method? oo design speaking think both equally compliant purpose.

is more expensive having each kind of menu static

that basic need of method overriding. , i'm not sure why going static

there no side effect/ expensive memory leaks, far not concern thread safety.

i'm suggesting bind them instances.
