Access private field of a instance object

Question

I have a class, which has one field named orbits (it has the same type as my class Body and has the private modifier):

Answer 1

Privacy is not per instance - it's per class.

The class can access the private fields of all instances.

For example, the method equals( Object o ) can cast o (if appropriate) to the same type, and compare its private members with the object on which equals() was called.
