?? I think Integer is fine? It is essentially
public class Interger
override operator = .....
But, still, Integer is not int. It cost extra pointer in memory. Unless I am wrong? Which no one has yet to explain how Integer is structured.
IMO, Integer[ one billion ] = ( 64bits pointer + 32bits value ) * one billion. Which is absolutly big no no in my previous examples.
And just for me only, I totally don't like to use objects when I can use primitives. Some people can debate this to death, but, I want to use int, that's all that matters.
