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

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.

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
