Finаl Prоject Directiоns: Interfаce Requirement (10 pоints) Creаte an interface named Cookable. This interface must contain one abstract method named getCuisine that returns a String. You will implement this method later. Encapsulation Superclass (10 points) Create a class named Appliance that implements Cookable. This class should contain: a heatLevel field (for example, 1–10) a 1-argument constructor get/set methods for heatLevel Validation rule If the heatLevel is less than or equal to 0, an exception will be thrown(this is handled in the Exception Requirement below) Implement getCuisine() It should return:"General cooking" toString() Return a message such as: "The appliance heat level is 6." Inheritance Subclass (10 points) Create a class named Oven that extends Appliance. It should: Contain a field for the brand Have get/set methods for the brand Have a 2-argument constructor (heatLevel + brand) Implement getCuisine() so it returns:"Baking" Create a toString() method that uses Appliance’s toString() and then adds the brand, for example:"The appliance heat level is 10. The brand is KitchenAid." Polymorphism Main Class (10 points) Create a main program that: Declares an array of 3 Cookable objects The first two should be Appliance objects The third should be an Oven object No user input is required Loop through the array and: Print the cuisine using getCuisine() Print the object using toString() Example Output So Far Cuisine: General cookingThe appliance heat level is 6.Cuisine: General cookingThe appliance heat level is 8.Cuisine: BakingThe appliance heat level is 10. The brand is KitchenAid. Exception Handling Requirement (10 points) We will validate heat level using a custom exception. Create a class named InvalidHeatLevelException that extends Exception. Its constructor should receive a message and pass it to the superclass, such as: “Invalid heat level: Heat must be greater than 0.” Update the Appliance Class: so that if the heat level is less than or equal to 0, the method throws InvalidHeatLevelException Appliance constructor Appliance setter Handle Exceptions in Main Use a try/catch block to handle the exception Display the error message if an exception occurs Attempt to create an Appliance with an invalid heat level (0 or negative) (This object should NOT go in the array, but the error should display.) Complete Example Output Cuisine: General cookingThe appliance heat level is 6.Cuisine: General cookingThe appliance heat level is 8.Cuisine: BakingThe appliance heat level is 10. The brand is KitchenAid.Invalid heat level: Heat must be greater than 0.
