You should take any reasonable book about UML and read at least basics. Moreover this page is not about asking if my homework is done correctly. You should ask about specific problems like "I have this relationship, in what direction should be my arrow" and even that only if you really can't find an answer and you'd really tried. As it's impossible to understand logic when you're that far from UML, I'm not analyzing it at all.
I'd recommend to read some basic literature about UML and then try again. This has so much in common with UML than paintings from my children with say Picasso. It is the program that is more important anyway.

Analyze the statement An important skill that you will start to develop in this module is analyzing a problem statement in order to identify the details needed to develop a solution. Design a solution: The design of your system should be consistent with the Object Oriented principles and easy to understand by an independent programmer. Improve this answer. Thank you very much for your answer.
I was wondering which one should be better - to implement the vehicle as an array or simply creating vehicle objects? Maybe we need some rules for people to logging and use this application. UML diagram maybe easy for above we don't use associations, use dependency.

Email Required, but never shown. The Overflow Blog. Each Object was built from the same set of blueprints and therefore contains the same components properties and methods. The standard meaning is that an object is an instance of a class and object - Objects have states and behaviors. A dog has states - color, name, breed as well as behaviors -wagging, barking, eating.
An object is an instance of a class. A class represent a concept which encapsulates state attributes and behavior operations. Each attribute has a type. Each operation has a signature.
The class name is the only mandatory information. Each parameter in an operation method may be denoted as in, out or inout which specifies its direction with respect to the caller. This directionality is shown before the parameter name. The choice of perspective depends on how far along you are in the development process. During the formulation of a domain model , for example, you would seldom move past the conceptual perspective.
Analysis models will typically feature a mix of conceptual and specification perspectives. Design model development will typically start with heavy emphasis on the specification perspective , and evolve into the implementation perspective. The perspective affects the amount of detail to be supplied and the kinds of relationships worth presenting.
As we mentioned above, the class name is the only mandatory information. UML is not just about pretty pictures. If used correctly, UML precisely conveys how code should be implemented from diagrams. If precisely interpreted, the implemented code will correctly reflect the intent of the designer. Can you describe what each of the relationships mean relative to your target programming language shown in the Figure below? If you can't yet recognize them, no problem this section is meant to help you to understand UML class relationships.
A class may be involved in one or more relationships with other classes. Select the UML Class diagram. Select Create. Need more help? Expand your skills. Get new features first. A subscription to make the most of your time.
