JAVA Access Specifiers:
Public: The public is the most wide-open access specifier. By using it we can make it available even outside the package without inheritance.
Private: Private is the most restricted access specifier. By using it we can make the methods or data members available only within the class itself.
Protected: Protected will make sure the data members and the methods are available only inside the package or subclass in different packages. i.e it is only available outside package the through inheritance.
Default: The Default access specifier will set the access level to within the package only. If we leave the access specifier blank then the default access specifier will be imposed.
