I have one line code:
return mapping.findForward( s.login( u.getUsername(), u.getPassword()));
Should I write 4 lines like
String username = u.getUsername();
String passwrod = u.getPassword();
String retval = s.login( username, password );
return mapping.findForward( retval );
多谢指教!

If you don't resue username, password, retval,
the style is fine as long as the logic's easy to understand.

Either is fine.
I write long code lines too, although sometimes I would break them up
to limit the # of nested (), or if the line gets too long. Sometimes
when I debug intermediate values, the long line gets broken up too.
The bottomline is readability. Although breaking them up helps reading
the particular line better, it may obscure the flow of code reading.
I sometimes pay more attention to a big block of code, but if is only a
simple thing, it would waste my energy.

Yeah, personally I like
return mapping.findForward( s.login( u.getUsername(), u.getPassword()) style
if it's not too long.
I seems to me more readable than the 4 lines version.

多写几行岂不显得工作量很大？

现在好像不按行计算工作量了

可以多留点空行，加点注释啥的，比写code还快。

lol, I think that most programmers hate writing comments.

For those methods with complicated or quirky logic, comments helps clarify
our thoughts and so forth reduce potential bugs and make maintenance easier
in future as well.

有句话叫做：剽悍的程序不需要注释

easier

.
IMHO, when it gets to writing comments for one's own code, EQ is more
important than IQ - one has to be careful to assume everbody reading the
code is neither an idiot nor a genius.
