Answer 1

iiiiiii.. is a local variable, i.e. it cannot be accessed from other classes. Therefore, its name does not matter; the compiler does not need to store it. Additionally, the compiler may look at your code and determine that {int i = 10;} is not actually doing anything and can be replaced by {} since both versions produce the same program output (none).
