I am newbie in J2EE & looking for strong basic behind each concept as, Why do we use private access specifier before each variable of type property bcoz ultimately to access it outside the class we use public method as getter & setter ? If we use getter & setter to access it outside the class so better we make variable as public so that it is easily available outside of the class... Please guide me why do we use as private ????
