But it's worth it if you can get a thorough understanding of these relationships in UML class diagrams. :)+++++++++++++++++

Of course, if the task is already close, you can also choose Remove to empty it. Second, UML class
In software systems, classes do not exist in isolation, there are various relationships between classes and classes, and UML provides different representations for different types of relationships.1. Related relationshipsAn Association (association) relationship is the most common relationship between a class and a class, and it is a structured relationship that is used to indicate that a
, generalization (generalization):is a class (called a subclass, sub-interface) that inherits the functionality of another class (called a parent, parent interface) and can augment its own new functionality, which is the most common relationship between classes and classes or interfaces and interfaces, and in Java such relationships are explicitly identified by t
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 ). However, it is worth it if you can thoroughly understand the relationships of UML cla
, the object as a local variable, call the static method of the class. The class that is called within the parentheses of a class function is dependent on itself. Because this relationship is weakly connected, from the point of view of high cohesion and low coupling, such code is optimally organized, whether it is object-oriented or process-oriented.There is a sp
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.

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.
