Nowadays, newly developed software packages are often obsolete already at the time of their introduction. Object-oriented software development is a possible--if not the only--solution to this dilemma: applications are modeled as software objects that describe the properties and the behavior of real-world entities. Such objects are encapsulated, in that they hide--behind a publicly known interface--the complexity of their internal data structures and behaviors. This enables objects to be used in a wide range of program packages without needing to know the details of their internal...

Neuentwickelte Software ist heute oft schon zum Zeitpunkt Ihrer Einfuhrung veraltet. Einen Ausweg aus dieser Krise bietet der objektorientierte Ansatz: Anwendungen werden als Software-Objekte modelliert, die sowohl die Eigenschaften als auch das Verhalten von Objekten aus der realen Welt beschreiben. Solche Objekte sind gekapselt und verbergen die innere Komplexitat hinter einer offentlich bekannt gegebenen Schnittstelle. Dadurch konnen Objekte in den verschiedensten Programmpaketen verwendet werden, ohne dass die interne Realisierung bekannt sein muss. Die Verbindung objektorientiert...
