Est-il possible d'avoir une saisie semi-automatique en utilisant jtextfield et une liste J?

1) vous devez trier votre tableau avant de l'utiliser pour de meilleures performances...

2) comme je l'ai mentionné que vous avez à prendre ces deux clasess

3) n'oubliez pas de définir la valeur initiale pour le meilleur et le plus beau de travailler avec ces Composants

simple sortie
