Access Specifiers in Java
An access specifier is a keyword that specifies how to access or read the members of a class or the class itself.
There are four access specifiers in Java as mentioned below:
- private
- public
- protected
- default
1. Private : Private members of a class are not accessible in other class either in the same package or in another package. The scope of private specifier is class scope.
2. Public : Public members of a class are accessible any where in the same package or another package. The scope of public specifier is Global.
3.Protected : Protected members are available in the same package. They are not available in the class of another package. You can access the protected members in sub class of same package or another package.
4. Default : Default members are available in the class of same package but they are not available in another package. The scope of default specifier is Package level.
