Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off, setting the desired temperature, and reporting the previously set temperature. The following methods provide this behavior: turnOn and turnOff , setTemp , which accepts an int argument and returns no value, and getTemp , which accepts no value and returns an int . Assume there is a reference variable myAC to an object of this class, which has already been created. There is also an int variable called currentTemp , which has already been declared. Use the reference variable, to invoke a method to retrieve the previously set temperature and store the returned value in currentTemp .
