Given the following class diagram, implement (write code for) the clone() method inside the SmartFridge class. The behavior of the clone() method must perform deep cloning. > Cloneable + clone(): SmartFridge > SmartFridge totalFridgesMade: int=0 - id: int {id} //unique ID - cpacity: int noOfDoors: int - engine: Engine Hint: public class SmartFridge... { //the code for the clone() method goes here }
