In UML models, enumerations are model elements in class diagrams that represent user-defined data types. Enumerations contain sets of named identifiers that represent the values of the enumeration. These values are called enumeration literals. You can add enumerations to depict discrete sets of values.
Open [Project Setting] tab and check the modeling language(s) you'd like to model with. 2. Select a Class in the Structure Tree or directly on the diagram, then go to its Property view, open [Language] tab and then tick <<enum>> to enable you to model an Enum.
To add an enumeration literal, right click on the enumeration class and select Add > Enumeration Literal from the popup menu. Then, enter the name of the literal and confirm editing.
They are simply showed like this:
_______________________
| <<enumeration>> |
| DaysOfTheWeek |
|_____________________|
| Sunday |
| Monday |
| Tuesday |
| ... |
|_____________________|
And then just have an association between that and your class.
If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.
Here's a picture of a slightly different example in ArgoUML:
Typically you model the enum itself as a class with the enum stereotype
