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 ????

Answer Posted / mmr
procedural oriented:-
int i=0;
int j=0;
int showi(){
print i;
}
void main(){
i++;// using i var with out knowing the intention of its use
could leads to unexpected behaviour
showi();
}
Object oriented:-
class mydata{
private int i=0;
int j=0;
private showi(){
print i;
}
void main(){
i++; // not allowed as i can be accessble only thru the
//member function that means the data will be operated thru
//the method exposed to access it which are private to the
//class
showi();
}
