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 ????

for example we are login into the irctc server from there it will go to the selected bank and deduct amount and come back to the irctc. so if we are developing this in java means will it be run on the same session. but as per my knowledge bank is separate and irctc is separate URL's so it will use two different sessions then how it is maintaining same session through out application and even it uses the payment gateway? how it is working can any one help me on that??
