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.
