Java access modifiers control the visibility of classes, variables, methods, and other members of a Java program.
What are access modifiers in Java?
Access modifiers are used to specify the scope of access of the member variable and methods of a class from a different class or package. The accessibility scope varies based on the modifiers you use. There are four access modifiers in Java –
- Default
- Private
- Protected
- Public
