Answer 1

Depending on the situation, it may be preferable to allow the direct modification of a field on a class only privately, and or through some method which associates semantics with the modification. This way it becomes easier to reason about this class and that particular value, since you can be certain that its modified only in a certain way. Moreover, at some point, an action such as incrementing and int may have additional required consequences at which point it makes more sense to expose access to it through methods.
