the train, the driver only operates the train, the actual internal or by the train braking system to force the train to stop; people close the door instead of people, imagine if the door does not have a rotating shaft you can not shut it, or the process of the encounter obstacles you can not shut it. 3. Class Diagram Drawing is very helpful in understanding and analyzing problems, do you have a better way

member variable;Dependency relationship (dependency)A dependency is represented by a set of dashed lines with arrows, such as a dependent on B; He describes the relationship of an object to another object while it is running;Unlike association relationships, it is a temporary relationship that usually occurs during operation and changes with the runtime, and dependencies can change;Obviously, the dependence also has the direction, the bidirectional dependence is one kind of very bad structure,

I know that rose can be very convenient for the reverse C + + code to the class diagram, share the following: STEP1: Create a new Rose project (a new one will be created by default when you open Rose) STEP2: Right-compoent view->new->compoent create a new component STEP3: Double-click the new compoent or right button->open specification set the component features, name random Name Ceguitest here, la

consistent.Just, the class involved in the association is logically a level, such as the student teacher above, but the aggregation involves the class is not a level.Look at the following example:It can be expressed as a has a/some B, at which point B is able to separate from a and exist independently. Without a car tire or a tire.Combination compositionThe composition relationship is a bit tighter than th

When reading other people's code without detailed documentation, how to quickly see the entire code structure (class structure) becomes a real problem. Today, I will introduce a method for automatically generating UML diagrams. Suppose I have a project folder: icultivator, which has a file Root. php (in fact, no matter how many levels of directories, multiple files can be used ). Lt ;? Phpabst When reading other people's code without detailed documen

Understanding 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 above, I intend to learn from the process of the JVM v

Different versions, the menu may not be the same, mine is 12.5 In this step, of course, you choose the Java class to invert. But it took a long time to find a way to import the folder.

class to know the properties and methods of another class, such as: teachers and students, the relationship between husband and wife can be two-way or one-way. Two-way associations can have two arrows or no arrows, and one-way associations have an arrow. "Code embodiment": member variable Arrows and points: solid lines with normal arrows, pointing to the owner In the picture above, the teacher and the stu

1. First, create your own class diagram and complete the settings of attributes and functions, as shown below: Supplement: the attributes and functions inherited from the parent class of the subclass must be manually written to the subclass view. For example, the ID attribute and GETID function in the stubrrower class
