Question

Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off. The following methods provide this behavior: turnOn and turnOff. Both methods take no arguments and return no value.

Assume there is a reference variable myAC to an object of this class, which has already been created. Using the reference variable, invoke a method to tell the air conditioner object to turn on.

Answer 1

Hi!

I will use JAVA to answer the question.

The class AirConditioner could be:

public class AirConditioner {

bolean state;

AirConditioner(){ //constructor

this.state = false;

}

public void turnOff{ //turn off method

this.state = false;

}

public void turnOn{ //turn on method

this.state = true;

}

}

Program to solve the problem:

public static void main(){ //main program

AirConditioner myAC = new AirConditioner(); //instanciate the AirConditioner object

myAC.turnOn(); //call the method turnOn for myAC instance.

}
