Adjust GUI for VendingMachineV2 (Given in class folder) which includes and Admin button. Write a ButtonHandler that will display the current balance of the Register when clicked (use JOptionPane to display) and the remaining Inventory of each Dispenser. Hour 14 Vending Machine GUI already provided below to help with question (please make sure it works before you reply. Also "Resgister" is spelled wrong but please leave it alone so there are no issues. )
