At compile time, however, the inner class Trackingslip is compiled at the same time as the other classes, except that it is invalidated by its own scope and beyond this sco

inner class, it is equivalent to mutual access between ordinary members, as if they were called each other between different methods in a class. Therefore, any member of the outer class can be accessed in the inner class, even if it is private. If you access non-static members of an inner
