...envoyé1 ; les attributs supplémentaires trouvés dans la chaîne JSON sont tout simplement ignorés. Si on veut prendre également en compte les attributs de la sous-classe, il faut ré-appeler la conversion, avec comme second paramètre la sousclasse. Les données JSON à transmettre étant nécessairement des chaînes de caractères, nous pouvons opter pour deux solutions pour les faire transiter dans la socket. Il n’est pas question ici d’utiliser la sérialisation de la classe String puisque la transmission serait cantonnée aux applications Java. Nous transmettrons une chaîne à un format standard, sous la forme d’une série d’octets (un o...
