My Java teacher said it was better to use ++n instead of n++, I am not seeing the logic behind this. Does anyone know?

My Java teacher said it was better to use ++n instead of n++, I am not seeing the logic behind this. Does anyone know?
++nincrements the value and returns the new one.n++increments the value and returns the old one.Thus,
n++requires extra storage, as it has to keep track of the old value so it can return it after doing the increment.I would expect the actual difference between these two to be negligible these days. I know a lot of compilers will optimize it so they’re identical if the return of
n++isn’t actually used, though I don’t know of Java does that.
