Vérifier si la souris est cliqué dans Java

Je suis en train d'écrire une interface graphique en Java. J'ai besoin de savoir comment faire pour vérifier si l'utilisateur clique sur la souris. Je sais comment faire pour vérifier la position de la souris, mais j'ai juste besoin pour vérifier si il est cliqué.
