Hierarchical relationship between java Collection interface and Collections Class, Class Diagram First, let's take a look at the difference between Collection and Collections. Collection and Collections are two completely different concepts. Collections is a java. util

Uml-unified Model Language Unified Modeling Language, also known as standard modeling language. is a language used to visualize modeling software-intensive systems.There are three main models in UML system development:Functional Model: Display the function of the system from the user's point of view, including use case diagram.Object model: Using the concepts of object, attribute, operation and correlation

The main purpose of this article is to continue to focus on the basic UML diagram. This month, we will learn more about the sequence diagram. Note that the following example is based on the new UML 2 Specification. Purpose A Sequence Chart is used to display the interaction between objects in a series of order of inter

Through the previous blog: the use case diagram of UML diagrams, we have completed the division of a software system use case and function module. Now we need to know how to further improve the static structure of the system. With the UML tool, we can obtain the static diagram of the static structure of the software s

It uses the "lifeline" of objects and the messages passed between them to show how objects participate in interaction. A sequence

Four types of relationships and code implementation of class diagrams in UML, and four types of uml In the uml diagram, the most complex relationships are generalization, implementation, dependency, and association, if you understand these relationships, you will become fami

0. PrefaceUnderstanding the JVM virtual machine principle is a necessary step for every Java programmer to practice. But because there are a lot of things in the JVM virtual machine to tell the relatively broad, in the current exposure to the JVM virtual machine principle of the tutorial or blog, the vast majority of the text-based description, it is difficult to give people a visual perception, after reading the feeling is still confused.Feeling the

UML-united modeling language, unified modeling language-is an object-oriented visual modeling language. UML uses a set of visualized graphical symbols (such as class diagrams) as the modeling language. These symbols can be used to visually describe all aspects of the system.
