Comment arrêter tous les clips en cours de lecture en Java avant d'en jouer un nouveau?

Question

Je fais une application Smart ATM pour mon projet de collège en utilisant Swing qui peut aussi être utilisé par des personnes ayant une déficience visuelle.

J'ai ajouté la souris sur les boutons de chaque bouton afin que le programme joue un clip qui parle du fonctionnement de ce bouton. Le problème est lorsque l'utilisateur passe au-dessus de plusieurs boutons dans un court laps de temps où un clip sur le bouton précédent est déjà joué, deux clips sont joués simultanément, ce qui n'est pas ce que je veux.

Mon code à ce jour pour la trame actuelle est:

Remplacer la méthode mouseExited pour chaque MouseListener, arrêter le clip dans la mise en œuvre

@Override 
public void mouseExited(MouseEvent e){ 
    theClipIManage.stop(); 
}
