Essayer de remplir un objet Rectangle avec un JPEG en Java

Question

Je travaille sur un projet de classe pour recréer un clone de Flappy Bird sur PC. J'ai ce code jusqu'ici (ci-dessous) mais je voudrais remplacer le rectangle rouge "oiseau" avec un JPEG d'un pingouin. Des idées sur la façon de s'y prendre? J'ai fait des recherches en ligne, mais je n'arrive pas à le comprendre. Je n'ai jamais fait de travail graphique 2D en Java. Je vous remercie!

Vous pouvez utiliser la drawImage() méthode de l'objet graphique:

g.drawImage(yourImage,xPos,yPos,null);
