Unfortunately, I don't know of any tools that support this neat little convention. Figure 6 A diagram using the non-standard shorthand notation for interface implementation.

We will go-over them in this UML guide. The figure below shows a generalization. We will talk about it later on in this UML guide.

We can indicate the multiplicity of an association by adding multiplicity adornments to the line denoting the association.
