In Java, access specifiers are the keywords which are used to define the access scope of the method, class, or a variable. In Java, there are four access specifiers. * Public: The classes, methods, or variables which are defined as public, can be accessed by any class or method. * Protected: Protected can be accessed by the class of the same package, or by the sub-class of this class, or within the same class. * Default: Default are accessible within the package only. By default, all the classes, methods, and variables are of default scope. * Private: The private class, methods, or variables defined as private can be accessed within the class only
