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();

   }

}
