Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off, and setting the desired temperature. The following methods provide this behavior: turnOn and turnOff, and setTemp, which accepts an int argument and returns no value. Assume there is a reference variable myAC to an object of this class, which has already been created. Use the reference variable, to invoke a method that tells the object to set the air conditioner to 72 degrees.

Answer:

public class AirConditioner {

   boolean turnOnOff;

   int temp;

//The Constructor

   public AirConditioner(boolean turnOnOff, int temp) {

       this.turnOnOff = turnOnOff;

       this.temp = temp;

   }

//Method to turnOn AC

   public void turnOn(){

       this.turnOnOff = true;

   }

//Method to turnOff AC

   public void turnOff(){

       this.turnOnOff = false;

   }

////Method to set Temperature

   public void setTemp(int newTemp){

       this.temp = newTemp;

   }

}

Explanation:

A test class where an object of the class is created is given below

class AirconditionerTest{

   public static void main(String[] args) {

//Creating the class reference        

AirConditioner myAc = new AirConditioner(true,72);

//Calling methods in the class      

myAc.turnOn();

 myAc.setTemp(72);

   }

}
