applications, such as class inheritance, abstraction, interfaces, and various associations. To use UML to design Java applications, we only need to use class diagrams to describe these static relationships. Using visual tools, we need to implement automatic generation of Java application code. We must also describe the cooperative and dynamic relationships among

Classes (Class) A rectangular box is used in UML to represent a class. Class diagram is divided into three layers, the first layer displays the class name, and if it is an abstract class, it is shown in italics. The second layer is the attributes of the class, usually the fields and properties. The third layer is the operation of the class, usually the method or the behavior. Note the preceding symbol, ' +

language for software engineering, which describes the system's class collection, the class's properties, and the relationships between classes. To help people to simplify the understanding of the system, it is an important product of the system analysis and design stage, and also is the important model basis for system coding and testing. Learning to draw a good class diagram is a skill that a qualified software engineer should have.UML Diagrams for

component through the HTTP protocol on the company intranet. The tool runs on the application server named w3reporting.myco.com. This figure also shows that the reporting tool component is drawn inside IBM WebSphere, and the latter is drawn inside the w3.reporting.myco.com node. Reporting tool uses the Java language to connect to its reporting database through the JDBC interface of the IBM DB2 database, and then the interface uses the local DB2 commu

Class diagrams are the most common UML diagrams used to describe the structural design of a system. These include class relationships and the properties and behaviors associated with each class. Class diagrams can represent an excellent representation of inheritance and composition relationships. To use the class diagram as an efficient communication tool, the developer must understand how to convert the el

The UML diagram and code expression of the relationship between classes and classes in java. If you need it, refer to it.

(Dependency) definition: for two relatively independent objects, when one object is responsible for constructing an instance of another object, or depending on the service of another object, the two objects are primarily dependencies. performance: dependencies are expressed in local variables , the parameters of methods , and calls to static methods . Example: If you're going to screw the screws, do you want to use (ie rely on) a screwdriver (screwdriver)

The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, the Unified Modeling Language). This course aims to show the highlights of UML. There are nine types of modeling icons in UML: Use case diagram

的建模最适合通过例子来描述。图7显示了4个组件：Reporting Tool、Billboard Service、Servlet 2.2 API和JDBC API。从Reporting Tool组件指向Billboard Service、Servlet 2.2 API和JDBC API组件的带箭头的线段，表示Reporting Tool依赖于那三个组件。 图7：组件图显示了系统中各种软件组件的依赖关系 回页首 部署图 部署图表示该软件系统如何部署到硬件环境中。它的用途是显示该系统不同的组件将在何处物理地运行，以及它们将如何彼此通信。因为部署图是对物理运行情况进行建模，系统的生产人员就可以很好地利用这种图。 部署图中的符号包括组件图中所使用的符号元素，另外还增加了几个符号，包括节点的概念。一个节点可以代表一台物理机器，或代表一个虚拟机器节点（例 如，一个大型机节
