thank you,szimek,chaitanyv.it seems we just need to rescue the
exception,and no need to re-raise exception.but i do not know why nearly
all the examples in the book <programming ruby> re-raise the
exceptions.i think i have misunderstood the exception in ruby.if an
exception raises in the end used method,we generally do a final
capture,and no need to reraise,am i right?
