Das erste ist das in der Hauptmethode definierte Fenster (dies sind feste Formate, es ist in Ordnung, wenn Sie nicht wissen, wie es geht, drücken Sie einfach Strg+C+V, im Grunde können Sie es verstehen, indem Sie sich einfach das ansehen Daten)
Schreiben Sie eine Superklasse. Die Superklasse muss die Breite und Höhe von U-Booten, Wasserbomben, Minen und Schlachtschiffen sowie die x- und y-Koordinaten ihres Erscheinens und ihre Bewegung haben Geschwindigkeit. Bilder aller Objekte, Bewegungsmethoden aller Objekte und Kollision. Es müssen zwei Schnittstellen definiert werden, eine dient zum Hinzufügen von Leben und die andere zum Hinzufügen von Punkten
Der vollständige Code lautet wie folgt (Sie können Bilder selbst finden, ändern Sie einfach die Bildklasse und die Breite jedes Objekts So hoch wie möglich)
