Recently relive a few design patterns, see everyone's blog is Java code +uml view, UML Express the overall framework, and then show the specific code, entire areas, at a glance. So we also studied how the Java
Next, create an association relationship between the classes, which allows you to select one in the aggregation and composition relationships. Figure 10 shows a high-level class diagram.Figure 10: High-level abstraction of UML class diagrams produced by semi-automatic methods By comparing Figure 10 with Figure 9, you can see that the semi-automatic method can accurately display the inter-class relationship
Today is looking at a simulator of the source code, a package has multiple classes, a class has a number of properties and methods, if in order to look down, not only can not be a general understanding of the framework of the simulator, and will only see the more chaotic, so, Think of any tools that can translate these classes and their dependencies into UML diagrams so that you can see them at a glance.

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 elements appearing on the class diagram into

[From frenzied, a Java developer]
A link is a link between things. There are four important relationships between classes: dependency, generalization, association, and implementation. These relationships can be mapped to the code.
Dependency is a usage relationship. Changes that describe the specification of a thing may affect another thing that uses it (and vice versa ). In

In the uml diagram, the most complex relationships are generalization, implementation, dependency, and association, if you understand these relationships, you will become familiar with understanding the
together in a war, and the soldiers have no life if the army is gone, they can be understood as a combination.
UML example:
Figure 3-1 Association, aggregation, and combination
C sample code:
[CPP]
View plaincopyprint?
// A Association/aggregation/combination of B
Struct {
Struct B * B;
Void (* Create) (B * B); // method 1
};
Struct {
Struct B * B;
through the keyword extends.
In Java, the extends keyword describes an inheritance form that inherits both interfaces and actions. This type of inheritance is sometimes called sub-classing. Unlike other object-oriented programming languages, Java classes can only inherit from one class. Many times, people who design UML diagrams are familiar with multiple prog
, interfaces and interfaces can be inheritance relationships, the parent class is also known as a base class or a superclass, a subclass is also called a derived class, the class inherits the parent class can implement the function of the parent class, and can have the function that the parent class does not have. In UML, the generalization relation can be represented by a straight line with a hollow triangle; for example, we

Click the Add a row icon to add properties, or click the Add Attributes icon to open the properties of other classes in the Selection window

Unified Modeling Language (UML) is a standard notation for building object-oriented system models. Between 1995-1997 and a half years, UML boarded the stage of the object-oriented programming community and was recognized by the Object Management Organization (OMG) in the late 1997. Although it was initially controversial-because it was put forward in a piece of support and opposition-
