Shadow variables

[Sharan Ashok Vasandani]

Hi,

Is shadowing of variables from Super Class in Sub class a good practice?
Is there a situation where it is a must and cannot be avoided?

It adds possible ambiguity. I'd prevent it if possible - and as far as I know it's always possible; just rename the variable.

Since there is virtually no limit on the allowed variable names it's almost always possible to avoid it, just by renaming it.

is variable shadowing a best practice or not?

If I say I'd prevent it if possible, does that sound like it's a good thing?
