Am a newbie to Java Programming and am studying Accessor Methods.
If you designate variables as "private", then you can change their
values using "accessor methods". So what's the point of making them
"private" if you can still manipulate them using accessor methods.
I find it really interesting that there are so many options available to
the programmer in Java regarding the visibility of variables yet most
people want you to wrap them in accessors (getters and setters :-). One
really handy reason to do that is to synchronize access. That and range
checking are probably the most valuable. Otherwise for a read/write
variable you've just added two more methods and the maintenance overhead
that goes with them. You will find some examples in Java itself of
exposed variables, although not many in more recent code. I know it's
not OO but since I started programming before there was OO I don't
really care. The code needs to be readable, maintainable, efficient and
most importantly it needs to be written to a budget. A public variable
here or there isn't going to hurt a thing.
choice of methodology now.
To Statement Considered Harmful" note. Does that mean I should use goto
