Re: which is a good instance variable

[shyam kishore alapati <sh...@mailnation.net>]

I think it purely depends on your requirement. But why do you want an InputStream as a class variable. I think that is very costly resource and you are blocking a resource.Others i think you can use it based on your requirement. For iteratorsif u declare it as class level variables if the underlying collection changes the iterator gets in valid.
