 ## Exercice 1
 * Création de la classe principale `CVDATPJUnit` et de sa classe de test `CVDATPJUnitTest` tous deux vides
+* Prototype de la méthode `swapTwoLast`, elle est statique car elle n’as pas besoin d’attributs de la classe. Ajout des test unitaires `swapTwoLastTest` et de la documentation dans la classe principale.
