BJP4 Self-Check 8.24: accessPrivateFields

Language/Type: Java classes encapsulation fields

Author: Marty Stepp (on 2016/09/08)

Sound F/X

When fields are made private, client programs cannot see them directly. How do you allow classes access to read these fields' values, without letting the client break the object's encapsulation?

You must change it to be public, then re-compile the program.
It is a trick question; private fields' cannot ever be accessed. That is the point of making them private.
You have to also declare the field with the 'friend' keyword for another class to access it.
Create an accessor method that returns the field's value.
Create another class with the same field, but make it public. Then the two classes can both see the private field.
