Hi Monica,
Well, its an option that language provides, you could use function to allow/disallow
access to class members
for eg
class sample
{
int ctr;
public void setCtr(int value)
{
ctr = value;
}
public int getCtr()
{
return ctr;
}
}
of course, you can set any/both of the above function to private to disallow access to
your member
alternatively, you could write them using property statements
class sample
{
int ctr;
public int Ctr
{
get
{
return ctr;
}
set
{
ctr = value;
}
}
}
the user of the class might have to write the code, as below if you are using a
function based approach
void main(String[] args)
{
sample s =new sample();
// if you want to increment value of ctr
s.setCtr(s.getCtr() + 1);
}
using property based approach,
void main(String[] args)
{
sample s = new sample();
s.Ctr++;
}
looking at both the examples, the property seems more natural to read & write, isnt it
?
I know this is really a simple example, but I hope it gives you a way to look at use
of properties
