Can someone tell me why do we use exception chaining, any practical example for the same ?

To keep the original exception. throw new Exception(oldException)

Did you try searching for "exception chaining"?

See if you can find a copy of Thinking in Java by Bruce Eckel; as far as I can remember he gives good examples. His opinion about Exceptions in the 3rd edition is completely different from the 4th edition, however

Please SearchFirst.
The first two Google search results for "Exception Chaining" would give you a better explanation with some practical examples.

it is about how an exception is related to another ...

let us say ... you get an exception say SQLException which happened due to some sql related confusion but in actual it is a I/O Exception ...

so the two exceptions are chained together ...

take a look at the complete reference ... although it is not enough but might help you understand some.
