UML diagram - how to show FINAL

How would I display the field

private static final int DAMAGE = 3;

in the UML Diagram?

Should it be shown as: - DAMAGE : 3 : int ?

For an UML representation of a Java project, it should be sufficient to write underlined caps, like…

A constant in a UML class diagram

Note that this representation uses a Java convention (constants written in capitals) to highlight it as final instead of a UML annotation, which would be kind of more straight-forward UML, but is too long for my purposes.

You show it like this.

enter image description here

Private is symbolized by a minus. The static attribute is shown by an underline. The initial value is shown by = <value>. Since I learned that final denotes a constant, you will apply the isConst property which is shown as {readOnly}.

See also p. 111 of the UML spec:

<property> ::= [<visibility>] [‘/’] <name> [‘:’ <prop-type>] [‘[‘ <multiplicity-range> ‘]’] [‘=’ <default>] [‘{‘ <prop-modifier > [‘,’ <prop-modifier >]* ’}’]

[ details omitted ]

No longer relevant in this context, but leaving it anyway:

Re. @granier's comment about tagged values: Indeed UML 2.5 does no longer really use tagged values. There are only 3 mentions of it:

  • mainly p. 205

    Just like a Class, a Stereotype may have Properties, which have traditionally been referred to as Tag Definitions. When a Stereotype is applied to a model element, the values of the Properties have traditionally been referred to as tagged values.

So tagged value is an "ancient" term and should further be called stereotype property.
