The three "allies" James Rumbaugh, Grady booch, and Ivar Jacobson created UML in 1995 and integrated their respective methods (OMT, booch development method, and OOSE) into a whole. In 1997, OMG used UML as an actual public standard. To a large extent, UML is a graphical language used to describe, record, design, and construct a solution. The powerful role of

UML modeling, it is important to understand the elements that appear on the class diagram. The developer must understand how to convert the elements appearing on the class diagram into Java. With Java as the representative of some examples of the Internet, here are some basic personal collection and summary: Basic element Symbols: 1. Class (Classes) The class consists of 3 components. The first one is the

Class) Class (FigureIs an object blueprint, which contains three components. The first is the class name defined in Java. The second is attributes ). The third is the method provided by this class. You can append a visibility modifier before attributes and operations. The plus sign (+) indicates public visibility. Minus (-) indicates private visibility. # Indicates protected visibility. Omitting these modifiers indicates visibility at the package level. If an attribute or operation has an under

Basic symbols of a similar graph can be split into dotted lines, arrows, solid lines, hollow right triangles, solid right triangles, hollow diamond and solid diamond. These basic graphs are combined to form the basic symbols of the class graph. The order of these symbols represents the Coupling Degree between classes. The greater the coupling, the higher the coup
