首先上图，根据图来学习: ------------------------------------------------------------------------------------------------------- UML结构: 图形矩形(代表一个类) 类名(斜体字代表是抽象类，名字第一排如果有<< interface >>代表接口) 特性(字段和属性，前面的符号有含义，+为public,-为private,#为protected) 操作(方法和行为，前面符号的含义同上) 线条实线 + 空心三角(继承关系，继承箭头方向父类) 虚线 + 空心三角 (实现关系，实现箭头方向接口) 实线 +箭头(关联关系，会引用到箭头所指类，“知道”有另一类) 虚线 +箭头(依赖关系，依赖箭头方向类，没有它就实现不了某些行为或者操作) 空心菱形+箭头(聚合关系，弱拥有关系，类似属性注入对象，箭头方向类是原点类的一个组成，生命周期不同，与合成关系不同，连线两端的基数表示几对几的关系) 实心菱形+箭头(合成关系，强拥有关系，类似构造器注入对象，箭头方向类是原点类的一个部分，它们生命周期都一样，谁离开谁都不行，连线两端的基数表示几对几的关系) 棒棒糖表示法(圆圈旁边就是接口名称，接口方法在矩形框里的操作里体现) 来源： https://www.cnblogs

Android: Creating UML from Android Java source code

阅读更多关于 Android: Creating UML from Android Java source code

问题 i am looking for a program that can create automatically an Uml from my Java-Android source code. I have tested ArgoUml, but it does not support Android. Have any one a suggestion? Thanks! 回答1: I can second what Tom Morris wrote in the comment above. Even ArgoUML should work. If you need improved (commercial) reverse engineering support you can try UML Lab - it can definitely read Java written for Android and has a free trial and free academic licenses (incl. support). If you have problems

问题 I have inherited a MatLab project with a bunch of MatLab files I need to refactor. It'd help me a lot to be able to generate a flow diagram or similar. I've Googled it and found other people asking the same question years ago, but nothing recent that works. This is the most recent thread about it: http://www.mathworks.com/matlabcentral/answers/28195-automatic-tool-to-generate-sequence-and-class-diagrams-uml I've seen there is some documentation about a tool to generate class diagrams from

第2章耗尽脑汁的需求分析工作摘要：怎么又变了？当初就应该让客户书面签字确认！你可能会经常发这样的牢骚，可是就算客户书面确认，客户还是会“赖账”的！软件项目的其中一项不变真理：人是会死的，需求是会变的！本章将会和你一起来体验软件需求分析工作的风风雨雨，找出需求分析工作的根本之道，了解 UML 如何帮助我们提升需求分析的水平。 2.3 给客户带来价值，需求分析之正路手机短信订餐系统接下来我将会介绍一个手机短信订餐系统的故事，这是一个由真实个案改编的故事，通过这个故事来体会需求分析工作背后的道理。某IT公司规模不大，员工100来人。公司有一个简单的定餐系统，员工每天可以在公司内部网站上提交当天午餐定餐，前台汇总各人定餐后，将定餐汇总传真给餐厅，餐厅根据传真送餐。可是有这样的问题：部分员工因为上午请假或者外出工作，无法再网站上提交订餐，以至于中午回到公司时没有饭吃。于是老板想出了这样的办法：做一个手机短信定餐系统，不在公司的员工可通过手机短信定餐。于是成立了手机短信定餐项目小组，购买了手机短信收发的硬件，解决了选餐单、定餐、取消定餐等技术问题。但这个系统一会灵一会不灵，问题是出在软件、硬件，还是中国移动都难以搞清楚！做项目做麻烦的事情之一就是遇到“幽灵问题”，时而出现时而正常，项目小组挥汗如雨地试图解决这些问题，可一直没有办法搞定。

What is the difference between sequence diagram and communication diagram?

阅读更多关于 What is the difference between sequence diagram and communication diagram?

问题 Could anyone explain me what is the difference between sequence diagram and communication diagram? 回答1: Both diagrams give the same information, but the sequence diagram emphasizes time in its layout and the communication diagram emphasizes the objects that are communicating in its layout. Time is implicit in sequence diagrams (it is inferred by vertical position), while it is given explicitly in communication diagrams (via numbers). To quote Scott Ambler The main difference between
