Bonjour, je suis occupé de faire un programme sous NetBeans et j'ai 2 fichier l'un pour mon interface graphique l'autre pour me connecter à mon port com et attendre que des données arrivent. Le problème est que lorsque je lance mon projet (les 2 fichiers sont dans le meme block) seul mon interface graphique se lance. Il doit exister un moment pour exécuter les 2 en meme temps en mettant une ligne dans mon programme main(interface) non?

Voici mes 2 fichier :

Main : (interface graphique)
