Can you debug my code? It is supposed to be a candy machine using three objects but there is an error I cannot find. Thank you Main: public class Main { public static void main(String[] args){ System.out.println("Press any number to start"); CandyMachine candyMachine = new CandyMachine();//asks for a number candyMachine.On(); } } Candy Machine: import java.util.*; public class CandyMachine{ CashRegister cashRegister; Dispenser candy; Dispenser chips; Dispenser gum; Dispenser cookies; CashRegister register; public CandyMachine(){ CashRegister register = new CashRegister(); Dispenser candy = new Dispenser(0.50, 20); Dispenser chips = new Dispenser(0.60, 20); Dispenser gum = new Dispenser(0.25, 20); Dispenser cookies = new Dispenser(0.85, 20); Scanner console = new Scanner(System.in); cashRegister = new CashRegister(console.nextInt()); } public void On(){ showSelection(); int choice; do{ Scanner input = new Scanner(System.in); choice = input.nextInt(); switch (choice) { case 1: System.out.println("That is not an option, please try again."); sellProduct(candy, register); break; case 2: sellProduct(chips, register); break; case 3: sellProduct(gum, register); break; case 4: sellProduct(cookies, register); break; case 9: break; default: System.out.println("That is not an option, please try again."); } } while (choice != 9); } private void showSelection(){ System.out.println("*** Welcome ***"); System.out.println("To select an item, enter "); System.out.println("0 for Adding more cash"); System.out.println("1 for Candy"); System.out.println("2 for Chips"); System.out.println("3 for Gum"); System.out.println("4 for Cookies"); System.out.println("9 to exit"); } private void sellProduct(Dispenser product, CashRegister cashRegister){ Scanner console = new Scanner(System.in); if(product.getCount() > 0){ if(product.getProductCost() <= cashRegister.currentBalance()) { cashRegister.deductAmount(product.getProductCost()); product.makeSale(); System.out.println("Collect item"); }else{ System.out.println("Plese try again!
