Consider the following: abstract class WashingMachine { public WashingMachine() { // Code to initialize the class goes here. } abstract public void Wash(); abstract public void Rinse(int loadSize); abstract public long Spin(int speed); } class MyWashingMachine extends WashingMachine { public MyWashingMachine() { // Initialization code goes here. } public void Wash() { // Wash code goes here. } public void Rinse(int loadSize) { // Rinse code goes here. } } What is wrong with the myWashingMachine class Which of the following are good candidates for instance variables for a class that you would define?
a. Private data whose values could be different for different objects of the class.
b. Constants used by the class and the client. Variables whose values are shared by all class objects.
c. Variables (like loop counters or temporary variables) used by most or all of your instance methods (in an attempt to avoid redeclaring these variables multiple times as locals for each instance method).
