Hypothetically speaking, how could adding a protected variable in a superclass create an error in Java? -

-

just fun, i'm trying think of scenario in protected variable can cause compilation error. lets had class fruit , class apple inherits fruit.

and go ahead , add protected variable x in fruit, causing program no longer compile. happen if how, causing error?

x inherited apple without problems. able use inside either fruit or apple. might decide override and/or implement setter and/or getter.

c# - Class in a list -

i understand in c# class passed reference. mean when store said class in list stored reference well, or better said c# style "pointer" of sorts? mean list n elements of class not take memory n times size of class n times size of reference class? or thinking wrong? you're right. if create n elements of class t, , class t uses, say, 10 bytes, takes on order of 10*n memory. if store in list<t> , still have 10*n memory objects, plus n times size of c# reference , list overhead. if store same elements in 2 lists, have 10*n objects, plus 2*n references, , 2 times list overhead. they're pointing @ same underlying objects.
