Can an exception be rethrown? | Rethrowing exceptions in Java without losing the stack trace

catch (WhateverException e) {
    throw e;
}

will simply rethrow the exception you've caught (obviously the surrounding method has to permit this via its signature etc.). The exception will maintain the original stack trace.

or

try
{
   ...
}
catch (FooException fe){
   throw fe;
}
catch (Exception e)
{
   ...
}
