《Introduction to Programming in Java》：http://introcs.cs.princeton.edu/java/home/
1、Whenever you can clearly separate tasks within a program, you should do so.
2、Whenever you create a library, you should include a main() method for unit testing and debugging.
3、Whenever you can clearly separate data and associated tasks within a computation, you should do so.
4、You do not need to know how a data type is implemented in order to use it. The flip side of this mantra is that a data-type implementation code can assume that the client knows nothing but the API.
5、Pay attention to the cost.
