How to use chained exceptions

Question

In my application I have never used chained exception. But I am really looking forward to use it as I believe it can make my code better. But being new to it can someone provide me with some example as in what type of scenario and how can it be used?

Not really clear but what you mean by chained exception, where did you come across the concept? — Elemental, Jul 11 '13 at 07:13

From docs directly

The following example shows how to use a chained exception.

try {

} catch (IOException e) {
    throw new SampleException("Other IOException", e);
}

In this example, when an IOException is caught, a new SampleException exception is created with the original cause attached and the chain of exceptions is thrown up to the next higher level exception handler.

Try like this

  try{
       .....
     }catch(ArithmeticExecption e){
                                      ....
                                  }
                                 .
                                 .
                                 .// u can add various exceptions like this
      catch(Exception e){
                          ....
                        }

//And if you are not sure which exception to use , use the more
general exception ,like i mentioned above
