Questions
Finаl Prоject Directiоns: Interfаce Requirement (10 pоints) Creаte an interface named Playable. This interface must contain one abstract method named getSport that returns a String. You will implement this method later. Encapsulation Superclass (10 points) Create a class named Ball that implements Playable. This class should contain: a size field (for example, 1–10) a 1-argument constructor get/set methods for size Validation rule: If the size is less than or equal to 0, an exception will be thrown(this is handled in the Exception Requirement below) Implement getSport() so it returns "General sport" Create a toString() method that lists the size of the ball, for example: “The ball is 6 inches.” Inheritance Subclass (10 points) Create a class named Basketball that extends Ball. It should: Contain a field for the brand Have get/set methods for the brand Have a 2-argument constructor (size + brand) Implement getSport() so it returns: "Basketball" Create a toString() method that uses Ball’s toString() and adds the brand, for example: “The ball is 10 inches. The brand is Spalding.” Polymorphism Main Class (10 points) Create a main program that: Declares an array of 3 Playable objects The first two should be Ball objects The third should be a Basketball object No user input is required Loop through the array and: Print the sport using getSport() Print the object using toString() Example Output So Far Sport: General sportThe ball is 6 inches.Sport: General sportThe ball is 8 inches.Sport: BasketballThe ball is 10 inches. The brand is Spalding. Exception Handling Requirement (10 points) We will validate sizes using a custom exception. Create a class named InvalidSizeException that extends Exception. Its constructor should receive a message and pass it to the superclass, such as: “Invalid size: Size must be greater than 0.” Update the Ball Class: so that if the size is less than or equal to 0, the method: throws InvalidSizeException Ball constructor Ball 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 a Ball with an invalid size (0 or negative) (This object should NOT go in the array, but the error should display.) Complete Example Output Sport: General sportThe ball is ready for play and it is 6 inches.Sport: General sportThe ball is ready for play and it is 8 inches.Sport: BasketballThe ball is ready for play and it is 10 inches. The brand is Spalding.Invalid size: Size must be greater than 0.
