Answer :
The status of the air conditioner can be checked by using the isOn method of the AirConditioner class on the object myAC, and storing the return value in the variable status.
To determine whether the air conditioner is on, the student needs to use the isOn method of the AirConditioner class. Assuming that there is a reference variable myAC for the air conditioner and a boolean variable status declared, the code to store the status of the air conditioner would be status = myAC.isOn();.
This would invoke the isOn method on the myAC object, and the return value, which indicates whether the air conditioner is currently on, would be stored in the variable status. If status is true, it means that the air conditioner is turned on. If it's false, the air conditioner is off.
