If I remember, it could be like a local variable which has the same name as an instance variable.

"name" in doSomething is shadowing the instance "name".

Another example is shadowing instance variables of a parent class.

changeIt() is passing the refference of Bar object.So its(passed obect's state) state is changed to 99.Then ,new bar object is assigend to this local refferece variable.Making changes (assigning 420)in this new bar object's state won't affect the called refference Object's state.So after completion of changeIt() method ,Bar object is barNum value is 99.

Esha NS, see this:

and change your user name please.


using the code tag on code that hasn't any indentations is pretty useless.

Same code indented:



Yours,
