1 Object-Oriented Programming Lab 7 1. Shape, TwoDShape, ThreeDShape, Disk, Square, Sphere, Cube class hiyerarşisi. Disk, kare, küre ve küp şekilleriyle çalışmak için abstract class larla birlikte bir class hiyerarşisi oluşturun. Shape - abstract class. - Türetilmiş class ların print(), scan(), area(), volume() metotlarına arayüz sağlar. TwoDShape - Shape class ından türetilmiş abstract class. - uble x // şeklin x koordinatı. - uble y // şeklin y koordinatı. ThreeDShape - TwoDShape class ından türetilmiş abstract class. - uble z // şeklin z koordinatı. Disk - TwoDShape class ından türetilmiş class. - uble r // diskin yarıçapı. - print(), scan(), area(), volume(). // diske göre tasarlanmış metotlar. Square - TwoDShape class ından türetilmiş class. - uble a // karenin kenar uzunluğu. - print(), scan(), area(), volume(). // kareye göre tasarlanmış metotlar. Sphere - ThreeDShape class ından türetilmiş class. - uble r // kürenin yarıçapı. - print(), scan(), area(), volume(). // küreye göre tasarlanmış metotlar. Cube - uble a // karenin kenar uzunluğu. - print(), scan(), area(), volume(). // kübe göre tasarlanmış metotlar. Oluşturduğunuz class ları bir programda deneyin: Her class tan birer obje oluşturun, kullanıcıdan koordinat ve boyut bilgilerini alın ve her bir objenin tüm bilgilerini (objenin şekli, merkez koordinatları, boyutları, alanı, hacmi) ekrana yazdırın.
