Study the constructs below and answer the questions that follow. interface Depreciable { void depreciate (double percentage); } 4 abstract class Item implements Depreciable{ protected double value; 6 8 10 12 public Item(double value) { this.value = value; } } class MultimediaItem extends Item implements Depreciable{ public MultimediaItem(double value) { super (value); } public void depreciate (double percentage) { value = value - (value (percentage / 100)); } 14 16 20 class CD extends Multimedia Item public CD (double value) { super (value); } } 24 public class Application { public static void main(String[] args) { 22 26 } The compiler will 4 in the Depreciable interface. The compiler will in the Item class. Which of the following may be added, independently, to the interface Depreciable. (Choose all that apply. Note that negative marking applies.) Oa. public abstract void setValue(double v) {} Ob. String name = "null"; Oc. double percentage; Od ; Jd. double boolean owned = true; Oe. public static double percentage; Of. int getPercentage(); = =
