Assume you have the following two classes: public class Bag { private String name; public Bag() { name = "Fancy bag"; } } public class Backpack extends Bag { private int noCompartments; // number of compartments in a backpack public Backpack() { noCompartments = 1; } %3D public int getNoCompartments() { return noCompartments; } } Assume that you have a variable of type Bag initialized to an object instance of type Backpack, as follows: Bag bag = new Backpack(); %3D Show a fragment of code to print the number of compartments in a Bag referenced by the variable bag, as assigned above.
