Drawing an abstract UML class on paper without italics?

Question

How should I represent an abstract class (in Java) in a UML diagram, taken manually on paper, without using an italic font?

Answer 1

You can use the annotation {abstract}under the class name.

It should look like this:

+---------------+
|   Classname   |
|   {abstract}  |
+---------------+

UML specifications c. 99:

The name of the abstract classifier is shown in italics, where permitted by the font used. Alternatively, or in addition, an abstract classifier can be displayed using the text annotation {abstract} after or under its name.
