“…While implementing relationships to many objects using collections (or similar reifications of multitudes) is by far the most commonly used pattern [26], automatic mappings from object-oriented models to programs may introduce other, more sophisticated patterns [18]. Both are however challenged by integrating relationships in object-oriented programming as a native concept.…”

In object-oriented programs, the relationship of an object to many objects is usually implemented using indirection through a collection. This is in contrast to a relationship to one object, which is usually implemented directly. However, using collections for relationships to many objects does not only mean that accessing the related objects always requires accessing the collection first, it also presents a lurking maintenance problem that manifests itself when a relationship needs to be changed from to-one to to-many or vice versa. Continuing our prior work on fixing this problem, we show how we have extended the Java 7 programming language with multiplicities, that is, with expressions that evaluate to a number of objects not wrapped in a container, and report on the experience we have gathered using these multiplicities in a case study.
