Suppose there is a class AirConditioner. The class supports the following behaviors: turning the air conditioner on and off. The following methods are provided for these behaviors: turn_on and turn_off. Both methods accept no arguments and return no value. There is a reference variable office_a_c of type AirConditioner. Create a new object of type AirConditioner using the office_a_c reference variable. After that, turn the air conditioner on using the reference to the new object.

The code is given in the explanation section

Explanation:

//Class Airconditioner

public class AirConditioner {

private boolean turnOnOff;

//The Constructor

public AirConditioner (boolean turnOnOff) {

this. turnOnOff = turnOnOff;

}

//method turn_on

public void turn_on () {

this. turnOnOff = true;

}

//method turn_off

public void turn_off () {

this. turnOnOff = false;

}

}

/ / A new class to test the airconditional class

class AircondionTest{

public static void main (String[] args) {

//Creating an object of the Aircondional class

AirConditioner office_a_c = new AirConditioner (false);

//Using the reference varible to call method turn_on

office_a_c. turn_on ();

}

}
