Private members of a class can only be accessed within the class itself and cannot be inherited by subclasses. Protected members can be accessed by subclasses even if they are in a different package and can be inherited. Private members make the data hidden and secure, while protected is less restrictive by allowing access to subclasses.

1. Explain the difference between private and proctected members of a class.
Solution
Hi, I am explaning difference between private and public in context of Java Programing
Language(since you have not mentioned any Programing Language).
private : Members marked private can not be accessed by code in any class other than the class
in which the priavte member was declared.
- A private member is invisible to any code outside the member's own class.
- When a member(function) is declared private, a subclass can not inherit it.
protected :Â Â Members marked protected can be accessed by a subclass(child class) even if the
subclass is in a different package.
