Answer 2

Private

Methods,Variables and Constructors

Methods, Variables and Constructors that are declared private can only be accessed within the declared class itself.

Class and Interface

Private access modifier is the most restrictive access level. Class and interfaces cannot be private.

Note

Variables that are declared private can be accessed outside the class if public getter methods are present in the class. Variables, methods and constructors which are declared protected in a superclass can be accessed only by the subclasses in other package or any class within the package of the protected members' class.

Public

A class, method, constructor, interface etc declared public can be accessed from any other class.

Therefore fields, methods, blocks declared inside a public class can be accessed from any class belonging to the Java Universe.

you can never ever make a class private🤓
