After ending the use case process analysis, I found that I have fallen into a dilemma, what is the meaning of this vocabulary, the author defines the use case as: "The use case is the system's end user has some useful results. Single task. So, in the real implementation part, should we use an example as a class or use case just some ways to be class? Analysis from the definition should be just a method and is not class. But should I start from the class or from a class method during the analysis of the surface object? Whether the vocabulary in the forebel should be the basic content of the class? And the information of the "OO Design Process" is not completed after the use case. But I can't wait for a tutorial to continue. The future content can only be carried out according to your own speculation, if you have a better solution, please discuss me.
Fortunately, I found http://www.javaworld.com/javaworld/jw-07-1999/jw-07-toolbox.html, is another article about OO, I hope to be able Some inspirations from it. And continue to approach our goals. to be continued
