此时，以当前选中的值调用plot方法，图形即被更新。

When that happens, the plot method is called with the currently selected value, and the graph is updated.

正如Linda所说，行为很简单：如果有人对null值调用push，那么栈应该抛出一个异常。

As Linda stated, the behavior is simple: If someone calls push with a null value, the stack should throw an exception.

模拟对象的一个额外功能是控制器接口，它使测试框架能够查询是否使用预期数据值调用了模拟对象。

An extra capability of the mock object is a Controller Interface that enables the test framework to query whether it was invoked with the expected data values.

I'd really like to have that modularity that says, I'm only going to get access to the values, not by calling their names, but by calling some specific method to get access to their names.

这样我们就丢掉了代码的模块化,我很希望代码有这样的模块化：,我访问变量的值，不是通过直接调用它们的名字，而是通过调用某个可以,访问这些变量名的方法来访问。

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 now if Christiana doesn't actually -- if either programmer or who's programming these little puzzle pieces, don't actually do anything with this return value, and I call, get int, she wants to hand this piece of paper -- to me, but if I don't actually assign -- no, no, I just messed up the demo.

现在如果Christiana没有-,如果程序员或谁在编写这段代码,不要对这个返回值做任何事情，我调用GetInt，她把这张纸给我,但是如果我没有赋值-,不，不，我刚才把这个演示搞乱了。
