Chronomètre en Java + bibliothèque Swing
salut,
Je cherche comment je peux faire un petit chrono qui compte jusqu'à 60s.
J'ai trouvé déjà ce code mais, il concerne les heures et les minutes en plus!

Mon problème c'est que je veux inserer ce chrono(du 1ère code) dans un JPanel qui se trouve dans un JFrame d'une autre classe.
Je veux quelqu'un m'aider pour résoudre ce problème là-dessus ou bien de me donner un petit code qui réalise ce chrono.
merci bien
