Questions tagged [public]

`public` is an access-specifier in object-oriented languages; it indicates that all objects have access to the `public` field or method.

In object-oriented languages, classes specify how much access other classes can have to their members.

When a member has the public specifier, other classes have full access to that member.

Other access specifiers are protected and private.

You can use this tag for questions about how the public specifier controls (or fails to control) access to the members of a class, and questions on how it interacts with the other access specifiers.
