现在，您可以为Web服务创建实现。

You will now create the implementation for the Web service.

youdao

创建实现类，并将其标注为Web服务。

Create the implementation class and annotate it as a Web service.

youdao

最后，需要为每个可能的子类创建实现。

Finally, you need to create the implementations for each of the possible subclasses. Listing 2 defines the subclasses for salaried employees and hourly employees.

youdao

And that's exactly one of the reasons why I want to have the functions, because I've separated those out.

这就是创建方法的原因,只是因为我把，实现和使用分离了。

What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.

组合成为有意义的单元,那么这就让我们回到,一开始讲的话题之一了,这就是抽象的概念,也就是我可以以一个简单的，实体的形式创建这样的一个单元，把具体实现隐藏然后写一些,真正模块化的代码,我们在以后的课程中。

But what looks like this orange block as of now in Scratch, add orange to your so called inventory, well, it's gonna take at least two lines of code in C to actually create the inventory array with this first line and then put something like the word orange inside of it.

就好比Scratch里面橘色的这一块，把“桔子“加到所谓的“清单“里面去,在C语言中至少需要两行代码来实现,第一行代码创建一个货单数组,第二行就需要把“桔子“放进去。
