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