好，如果你们知道，抱歉，让我们换种说法,我不必担心检查工作,是则会么做的，这是在方法体内部进行的。

I'm much better having an exception get handled at the time of input than to let that prop -- that value rather propagate through a whole bunch of code until eventually it hits an error 17 calls later, and you have no clue where it came from.

不是我期望的格式,这时我最好有一个异常处理,而不是让其传下去,这个值传到代码的整个分支,最终会导致一个错误17调用的发生，并且你不知道这个错误是哪里来的。

So I'm going to distinguish in fact between un-handled exceptions, which are the things that we saw there, and handled exceptions. I'm going to show you in a second how to handle them, but let's look at an example.

所以我打算区分开不可处理的异常,以及我们刚才看到的,可以处理的异常,我一会要给你们演示下如何处理他们,给你们看一个例子。
