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 ????

Hi All,
I think that the access modifiers of Java comes under the
umbrella of encapsulation.If you don't protect your
variable through the access modifiers or if you just make
them final then all the values of those variables can be
changed at any point of time because the variables are used
by many classes as Java is designed to make the code
reusable.You create a variable by using private and
generate the public getter and setter for that
variable.Using this way you can access your variable you
can assign new value in the variable but you can't change
it.
