Explanation / Answer

DECLARE A VARIABLE AS PROTECTED

the variable which has private access modifier cannot be accessed outside the class whether it is inherited to a child class. the default access modifier gives that permission, it is always better to mark a variable private or protected rather than default but in the current case if the variable needs to be get inherited in child class, than for that case the modifier must be declared to protected.

Private members exists in the instance of a child class, therefore the object of sub class is also an object of super class, so they are accessible indirectly with the help of non private method of super class. this can access and manipulate the private members
