Given:
public final class IceCream {
public void prepare() {}
}
public class Cake {
public final void bake(int min, int temp) {}
public void mix() {}
}
public class Shop {
private Cake c = new Cake ();
private final double discount = 0.25;
public void makeReady () { c.bake(10, 120); }
}
public class Bread extends Cake {
public void bake(int minutes, int temperature) {}
public void addToppings() {}
}
どちらの説明が正しいですか？
