C’est donc l’un des chapitres les plus importants de tout le livre et il présente des fonctionnalités indispensables à pratiquement tous les programmeurs Java.
Dans ce chapitre, on va présenter les interfaces fondamentales et la hiérarchie des types, montrer comment les utiliser et aborder certains aspects de leur conception globale. On abordera à la fois l’approche « classique » de la gestion des collections et la nouvelle approche basée sur l’API Java Streams.

Les Collections Java constituent un ensemble d’interfaces génériques qui décrivent les formes les plus courantes de structures de données. Java est livré avec plusieurs implémentations de chacune des structures de données classiques, et comme les types sont représentés sous forme d’ interfaces, les équipes de développement peuvent créer – et ont d’ailleurs déjà créé – leurs propres implémentations spécialisées de ces interfaces, destinées à être utilisées dans leurs propres projets ou à être partagées sous forme ...
