What are access modifiers?

Access modifiers decide whether a method or a data variable can be accessed by another method in another class or subclass.
four types of access modifiers:
Public: - Can be accessed by any other class anywhere.
Protected: - Can be accessed by classes inside the package or by subclasses ( that means classes who inherit from this class).
Private - Can be accessed only within the class. Even methods in subclasses in the same package do not have access.
Default - (Its private access by default) accessible to classes in the same package but not by classes in other packages, even if these are subclasses.
