Question

You are assigned to implement the following baggage-check-in system at the airport.

The system keeps track of data for the following information: passenger, bags, and tickets.

The program must maintain passenger details like name, address, phone number, and the number of bags. Each passenger can have multiple bags and each bag has length, width, height, and weight. The passenger also has a ticket. The tickets are of two types, either a first-class ticket or an economy-ticket. The maximum weight allowed for a first-class ticket is 40 Kilos and the maximum weight allowed for an economy-ticket is 30 Kilos. The program must display all the details of the passenger, ticket, and number of bags and allowed weight. If the weight exceeds that of the respective ticket class, then the program will give appropriate message to indicate that the passenger cannot travel. Your program must throw an exception to indicate the failure.

Requirements

• Implement the following functions:
  1. checkOverweigth() # Given the ticket number, check if the total weight of all bags exceeds limit
  2. checkPassengerClass() # Given the ticket number, the class of the ticket is given
  3. displayPassengerDetails() # Given the ticket number, display all check-in details of a passenger
• Student is required to identify classes, related attributes, and behaviors. Students are free to add as many attributes as required. The appropriate access modifiers (private, public, or protected) must be used while implementing class relationships. Proper documentation of code is mandatory.
• Student must also test the code, by creating at-least three objects. All classes must have a display function, and the program must have functionality to print current state of the objects.
