C++ uses the three modifiers called public, protected, and private. [3] C# has the modifiers public, protected,internal, private, protected internal, private protected, and file. [4] Java has public, package, protected, and private; package is the default, used if no other access modifier keyword is specified. The meaning of these modifiers may ...
The following is a common set of access specifiers: [10] Private (or class-private) restricts access to the class itself. Only methods that are part of the same class can access private members. Protected (or class-protected) allows the class itself and all its subclasses to access the member. Public means that any code can access the member by ...
Many modern languages, including C++ and Java, provide a "protected" access modifier that allows subclasses to access the data, without allowing any code outside the chain of inheritance to access it. The composite reuse principle is an alternative to inheritance. This technique supports polymorphism and code reuse by separating behaviors from ...
Methods may also be designed public, private, or intermediate levels such as protected (which allows access from the same class and its subclasses, but not objects of a different class). [44] In other languages (like Python) this is enforced only by convention (for example, private methods may have names that start with an underscore ).
In object-oriented programming, a friend function, that is a "friend" of a given class, is a function that is given the same access as methods to private and protected data. [1] A friend function is declared by the class that is granting access, so friend functions are part of the class interface, like methods.

A third, protected, extends permissions to all subclasses of the corresponding class. Access levels modifiers are commonly used in Java [1] as well as C#, which further provides the internal level. [2] In C++, the only difference between a struct and a class is the default access level, which is private for classes and public for structs. [3]
