Create a class for each (staff, passengers, tickets). Please apply the following concepts whenever they are necessary: abstraction, encapsulation, inheritance, static, method overriding, and use of interface. b. Create an ArrayList of 2 objects of each class ask the user to enter their information, and create a method to print their information. c. Create a method to calculate salary of staff, taking into account of type employee (accountant, receptionist, flight attendant, pilot, etc.). Assign each type of employee with a salary that you see fit. The method will calculate employee salary after a 15% tax rate.
