Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off, and checking if the air conditioner is on or off. The following methods provide this behavior: turnOn and turnOff , setTemp , and isOn , which accepts no argument and returns a boolean indicating whether the air conditioner is on or off. Assume there is a reference variable myAC to an object of this class, which has already been created. There is also a boolean variable status , which has already been declared. Use the reference variable, to invoke a method to find out whether the air conditioner is on and store the result in status .
