An Access Modifier is a Object-Oriented Language keyword that sets accessibility of classes, methods or members.
- AKA: Access Specifier.
- Context:
- It can range to being a Class Level Access Modifier to being a Member Level Access Modifier.
- It can range from being a Protected Access Modifier, to being a Public Acess Modifier, to being a Private Access Modifier, to being Package Private Access Modifier.

- Access modifiers (or access specifiers) are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. In C++, there are only three access modifiers. C# extends the number of them to six, while Java has four access modifiers, but three keywords for this purpose. In Java, having no keyword before defaults to the package-private modifier.
When a class is declared as public, it is accessible to other classes defined in the same package as well as those defined in other packages. This is the most commonly used specifier for classes. A class cannot be declared as private. If no access specifier is stated, the default access restrictions will be applied. The class will be accessible to other classes in the same package but will be inaccessible to classes outside the package. When we say that a class is inaccessible, it simply means that we cannot create an object of that class or declare a variable of that class type. The protected access specifier too cannot be applied to a class.

- QUOTE: Access modifiers specifies who can access them. There are four access modifiers used in java. They are
public,private,protected,no modifer(declaring without an access modifer). Using ‘no modifier’ is also sometimes referred as ‘package-private’ or ‘default’ or ‘friendly’ access. Usage of these access modifiers is restricted to two levels. The two levels are class level access modifiers and member level access modifiers.
