How to create a Class Diagram

[tantra]

I'm beginner in this field.




I have build the class diagram, but I'm so confuse with PRIORITY ( I need to put priority 1 to 5).
Can you suggest to me anytihing else



thnx for help...

You will need an enumeration for Priority, and use that as the type of your attribute Contract.priority
The enumeration Priority should then contain the values 1-5 (without a type)

Hi Geert,

I've set priority, the priority is the value at 1-5, can you tell me specifically what to do.

Thank you for helping me

I don't know where lies Contract.priority because I am new in UML (am learning), can you tell me where is located Contract.priority, lacking only a priority from 1 to 5 the application is or should rule the other thing

In your class "Contract" you have an attribute "priority: int". That should be "priority: Priority".

Hi, now is it OK?

[Geert Bellekens]

No,

The class Priority should be an enumeration.
Look in the toolbox. There should be an icon for enumeration.
Drag that onto your class diagram and add the values 1-5 via the attributes.

No, you now have a class with the name "enumeration".
You need an enumeration with the name "Priority".

Please lookup "enumeration" in your UML book/course (or even in the EA help file)

you'll want to do something like this:



You'll also want to name your enum more reasonably. Like "Low, Medium, High" instead of "Priority1" etc.

[Geert Bellekens]

Typically you wouldn't add a type to your enumeration literals.
So you would have attributes with priority1 as name, but without a type.
The fact that you can assign something like an integer to an enumeration value is a programming construct, but not supported in UML.

However the EA documentation speaks otherwise:

Or am I gettin something wrong?

[beginner]

The ordinal value for the enum is typically supplied by the compiler (much later then). It might start from 0 or 1. But you're free to add numbers if you so wish.

P.S. What is this here? An UML lecture? To the thread creator: go and do your homework first...

What do you think she is trying to do

I build this diagram, can you tell me exactly what I do for the diagram be OK?

Read the requirements detailed in your specification. Do you think that all of the are fulfilled? I don't.
