Those seem to be two different and unrelated questions.

Ok. Thanks..I would like to know the answer for my second question..if we just mention method throws exception (without being more specific) , is there any performance impact for the application?RgdsSiva

I don't think there is a performance problem (as in, your code won't run any slower). The main problem is when you use a try catch with just Exception, because the feedback from the program isn't going to be detailed enough to help you debug it.

When we ran some tools for performance for code review, it shows that exception should be specific wherever we declare..In some code there may be thousands of methods that does not mention thowing specific exceptions...

In best practices of using exceptions it has been said that when we declare a method capable of throwing an exception we need to mention more specific exception...If there is no performance impact, why it has been recommended in best practices ?

Sounds like a homework question you need to answer not us.

Not everything revolves around performance, especially when it comes to best practices. Just looking up "best practices" on wikipedia should get you started with answering this question.
