description, we should be clear about the relationship between the various relations and what the code is like, the so-called degree of repetition, it is just an extension above. For example, if a and B have a "one-to-many" repetition degree, there is a list in a that stores n references of object B, that's all.
Now, I have finished the class graph relationship above. I hope you will get something better. I have also spent a lot of time (drawing, generating code, writing to blog, alas, a sweat

team and the team (as shown in ).
The "employee" and "employer" on the two sides of the Association indicate the relationship between the two, while the number indicates the restriction of the relationship between the two, which is the multiple correlation between the two. There are usually "*" (indicating all, not limited), "1" (indicating there is only one), "0... "(0 or more)," 0, 1 "(0 or one)," n... m "(meaning n to m)," m... * "(at least m ).

The existence of UMLClass diagram is a UML diagram with high frequency, which is used to describe the classes contained in the system and the relationship between them, to help people to simplify the understanding of the system, is also an important product of the system analysis and design phase, but also the important type of system coding and testing basis.How
Unified Modeling Language (UML. It includes the following important functions:
Visualizing)
Specifying)
Construting)
Document creation (documenting)

User case diagrams)

diagramsThere are four kinds of relationship between class diagram: Generalization relation, realization relation, dependency relation, association relation, and association relation is divided into common relation, aggregation relation and synthetic relation. But in fact these relationships we easy to understand, but many other times we have to pay attention to how to translate into Java code:Generalizati
Summary of the following four relationships

2. Aggregation
3. Dependency
4. Join

The various elements of UML are not mentioned here, I just want to talk about the relationship between classes in the class diagram, can understand the class diagram of the lines between the classes, arrows represent what meaning, it is enough to deal with daily work and communication, at the same time, we should be able to express the meaning of the class
operations, no operation implementation. In UML, the interface is represented in a way similar to the class notation, as shown in 3:
Figure 3 UML diagram of the interface
Interfaces can also have inheritance and dependency relationships similar to the relationships between classes, but there is also a realization relationship between interfaces and classes. In
UML Class diagram: To understand the class diagram of the lines between the various classes, what the arrow means is enough to deal with day-to-day work and communication, and we should be able to match the meaning of the class diagram to the final code; With this knowledge, there is no problem with the design pattern

Synthesis (composition)
Synthesis ( fig. G) is a special form of aggregation, implying "local" within the "whole" life-cycle responsibility. Synthesis is also not shared. Therefore, while the part does not necessarily have to be destroyed with the destruction of the whole, the whole is either responsible for maintaining a partial survival state o
