J'aimerais que quelqu'un regarde le code suivant et dis-moi s'il y a quelque chose qui cloche/bizarre. Je suis à la recherche de conseils généraux en codage. Si vous pouvez simplement me diriger dans la bonne direction, ce serait formidable.Guide de programmation Java
Je suis très nouveau à Java. J'ai écrit et réécrit les dizaines de fois suivantes et ça marche bien. Je veux juste que quelqu'un jette un oeil pour voir si quelque chose apparaît comme manifestement faux.
