Question : If one member of a class is private, all the members of that class must also be declared as private.

Answer : False

:::::::::::::::::::::::::::::::::::::::::::: EXPLANATION ::::::::::::::::::::::::::::::::::::::::

we have 3 types of access modifiers

1. private - members are accessible with in the class
2. protected - members are accessible with in the package and outside of package by sub class
3. public - members are accessible inside/outside of class.

Every member has an access modifiers. It depends on how we access the members.

We have following members

• constructor
• Variables
• Methods
• Inner class
• blocks

If we want a member to use with in the class we can use any access modifier.

If we want to use a member outside class we use either of the access modifiers except private.

If we want to use a member from any where, we must use access modifier public.

Assigning access modifier is depends upon how we access the data from class.

It is not necessary to make all class members as private.
