----

<1> l’execution entrera dans le bloc si l’objet pointé par la variable `a` est de type `ArrayList` ou d’un sous-type d’ `ArrayList`

Classiquement, tester le type d'une variable est suivi par un *cast* :

[source,java]
----
void callBarkIfPossible(Animal animal) {
if (animal instanceof Dog) {
Dog dog = (Dog) animal; // <1>
dog.bark();
}
}
----
<1> Ce type de *cast* est appelé *downcasting* (passage d'un type parent à un type enfant)

A partir de Java 16 l'opérateur `instanceof` peut prendre une opérande supplémentaire afin d'obtenir directement une variable du type testé :
[source,java]
----
void callBarkIfPossible(Animal animal) {
if (animal instanceof Dog dog) {
dog.bark();
}
}
----

=== Nommage

Le nommage a un intérêt prépondérant dans le paradigme objet où le développeur essaie d’exprimer des concepts réels.
