return_value, 然后所有函数的 caller 都必须强制 check和处理这个值呢? 这样算是
算用 return value 实现了 exception?
我的意思是说，编程语言本身，在未知错误下，能确保 function 返回这个
unexpected_return_value.
当然，很久前学 C++ exception 时候，记得说 exception 还有个所谓好处: 把处理错

首先字典不是法律，给出的解释是suggestion,不是definition.具体的意思必须根据常
用法和语境得出。
另外以下三个解释中，最接近罗格的意思是(2)，但是(2)翻译成中文后多了个常规的规
字，然后你根据这个规字得出结论就是exceptional是指规模上的大小，这就失之毫厘
谬之千里了。
Exceptional means something that is so good that people don't or cannot
expect it. It contains a suggestion that this is not something subjectively
good, it is objectively good regardless the stance of the observer. That is,
it can be as good as beating statistics odds. It contains another
suggestion that this is something so |

发帖数: 16778 | 26 although the meaning is the same, I am still curious about the difference.
I guess there should be some kinda differences.
why?
because 'except that' is followed by a past tense verb and
if not by a past perfect tense verb.
except that is not virtue tense, but 'if ..had not' is a virtue tense.
what does it exactly mean when a 'would have been' is followed by
a clause with a past tense verb? |

我不同意你的看法。如果一个方法要catch多种exception，并把它转化成MyLibException
，
那么应该对MyLibException单打catch否则你会有多层MyLibException套在一起，这也是
exception handling里面手脚不干净的表现。 |

近
光知道catch不行，还要知道擦屁股的重要性。比如说这样写就不对：
try{
Connection conn = dataSource.getConnection();
PreparedStatement stmt = conn.prepareStatement("Select * from myTable");
ResultSet rset = stmt.executeQuery();
...
}catch( SQLException e ) {
...
}
原因是在出了exception后你没有办法擦屁股。所以要把conn, stmt, rset全部在try{}外
面
declare,然后在catch后面写
fianally{
if( rset!=null）｛
try{
rset.close();
}catch (Exception e )｛
//ignore
}
}
...
}
把rset, stmt和conn全部关闭。用finally还有个大忌就是在finally里面绝对
不可以返回, 更不可以返回值。 |

Technically, an uncaught exception does not halt the entire jvm (if that's
what you meant by "system"). If I'm not mistaken, it ends up killing the
thread throwing the exception - of course, if that thread happens to be the
main GUI thread in a Swing app, it would indeed appear to have halted the
entire system. 8-) |

int *p;
try {
c = a / b ;
p = new int [300000000]; //3Gmemory
}
catch (...)
{
cout << "error";
}
应该出现两个exception，一个是divided by zero,一个是failed to allocate memory，
本意是应该让catch 来输出出错，并不中断程序执行。
但是编出来的程序不能catch任何一个exception,程序还是会被中断。这到底是什么原因
呢？哪位高手指教一下吧。

it is possible that b = 2 executed before a = 1;
second:

A a;
B b;
is it possible that B b executed before A a?
last:
class A {

};
A a; // exception is thrown within constructor of A
B b;
is it possible that B b executed and b constructed before the exception is
thrown? |
