Bonjour,
J'ai récupéré sur le site de référence de Google sur les API Javascript, ce petit exemple ci-dessous que j'ai modifié :

Cet exemple fonctionne très bien, et je sollicite votre aide pour transformer cet exemple mais en utilisant les API JAVA de Google Maps.

Est-ce possible ? Si oui, comment faire ?

Je vous remercie par avance pour vos réponses.
