The default access level is available when no access level is specified. All the classes, data members, methods etc. which have the default access level can only be accessed inside the same package. A program that demonstrates the default access level in Java is given as follows: Now let us understand the above program.

4. Default (no modifier): The default access modifier (also called package-private access) in Java is used when no explicit access modifier (public, protected, or private) is specified. It allows class members (fields, methods, constructors) or classes themselves to be accessible only within the same package.

First, when you use classes that come from another source, such as the classes in the Java platform, access levels determine which members of those classes your own classes can use. Second, when you write a class, you need to decide what access level every member variable and every method in your class should have.

This is the default access level if no other modifier is specified. Class: A class with no modifier (also known as package-private) can only be accessed within the same package. Method/Variable: Methods and variables with no modifier are accessible only within the same package.
