À l'aide de méthodes getter et setter en Java

Essayer de créer un projet qui utilise la saisie de l'utilisateur et les informations de déterminer combien une voiture de location, les coûts par jour. Le problème, je vais avoir, c'est la location de voitures de classe ne semble pas être obtenir l'entrée à partir de la classe de test. Vous ne savez pas comment le résoudre.
