UML class diagrams allow us to denote the static contents of—and the relationships between—classes. In a class diagram we can show the member variables, and member functions of a class. We can also show whether one class inherits from another, orRC Martin...

protected和private不能修饰外部类, default有时也被称作friendly(沿用c++的叫法,虽然java中并没有此修饰符) 为了表示独立性,尽量不用public修饰成员变量 各修饰符的访问权限见下图: 在class diagram中 public用+表示,protected用#表示,private用-表示。 二、类之间的关系 1. 继承Inheritance (1)泛化Generalization: ...

类图(Class Diagram) 在UML的静态机制中类图是一个重点,它不但是设计人员关心的核心,更是实现人员关注的核心。建模工具也主要根据类图来产生代码。类图在UML的9个图中占据了一个相当重要的地位。 James Rumbaugh对类的定义是:类是具有相似结构、行为和关系的一组对象的描述符。类是面向对象系统中最重要的构造块。
For example, a class diagram for a dialog system might show the relationship between a dialog manager class, which is responsible for managing the flow of the dialog, and a language model class, which is responsible for understanding and interpreting user input. The class diagram might also show...
Class Diagram: 类图中, BootstrapClassLoader是一个单独的java类, 其实在这里, 不应该叫他是一个java类。 因为, 它已经完全不用java实现了。 它是在jvm启动时, 就被构造起来的, 负责java平台核心库。(具体上面已经有介绍) 启动类加载实现 (其实我们不用关心这块, 但是有兴趣的, 可以研究一下 ): ...
