Having the get() method makes the entire purpose of Optional useless. All it does is make your null-checking code even more verbose. If you need to extract the value, the orElse method should be suitable on all cases. Deprecating get() should be an instant decision, since other than backwards compatibility it has nothing to add to the Optional class. Including it in the first place was as much of a mistake as the null pointer.
