- Private – Like you’d think, only the class in which it is declared can see it
- Package Private – Can only be seen and used by the package in which it was declared. This is the default in Java (which some see as a mistake)
- Protected – Package Private + can be seen by subclasses or package member
- Public – Everyone can see it
