注意抽象类如何定义一个构造函数，该函数接收属性的一个map—我总是可以稍后添加更多构造函数，稍后我就会这么做。

Note how the abstract class defines a constructor that takes a Map of properties - I can always add more constructors later, and I will shortly.

OK, so what have I done? I just added a little bit more now. I'm now running through a pair of loops. Again notice the encapsulation, that nice abstraction going on, which is what I want. Once I get to this stage though by the way, there might be more than one solution.

我现在运行了一对循环,再一次注意这个封装,抽象得很好，这就是我想要的结果,我按这种方式走到这一步的时候,可能会有多组答案。
