Designing Flight Object Model for SkyReserve System
Business Scenario
Welcome back,Developers!
In the previous lab, we built the Flight Seat Booking System, where passengers could select and reserve seats using a 2D array. The system now knows who is sitting where.
But what about the flight itself?
Every booking belongs to a specific flight, and the application must store details such as :
Instead of keeping these details in separate variables, we need a structured way to represent a flight.
Your next task is to design a Flight Object Model. Create a Flight object to store all flight information and use constructors to initialize it, enhancing organization and management.
Pre-Lab Preparation
git pull origin branchName
Git Pull
Task 1: Defining the Flight Model
1
Create a new Java Project - FlightModelOOP
Topic :
1) Object creation and use of Scanner to set the instance variables
2) Declaring constructors and using constructor to set the instance variables
3) Declaring toString()
2
Create a new package ‘com.itvedant.flightmodeloop.models’ and a new class Flight
3
Declare the instance variable to store the Flight data and declare the
main method and create the object of Flight class
3
Declare the instance method ‘displayFlightDetails’ to display the flight object details
5
Call the method from main method to display the details of flight object
4
Declare the instance method ‘displayFlightDetails’ to display the flight object details
6
Run the code
Task 2: Accepting the user input
Declare the method setFlightDetails to accept user input and set the object
1
Call the method from main method
2
Run the code to and check the output
3
Task 3: Declaring Constructors
Declare the zero constructor (note that the Constructor name must be same as classname)
1
In main method, create the object and then call the method to set the flight details
and display the same
2
Run the code to and check the output
3
Task 4: Declaring Parameterized Constructors
Declare the parameterized constructor
1
Create the flight object, by calling parameterized constructor, in the main method
2
Define the toString() to display the object details
3
Display the flight object within the main method and run the code
4
Great job!
You have successfully created your first Flight Object Model using classes, objects, and constructors. Your SkyReserve system can now represent flight information efficiently.

Next-Lab Preparation
Topic :
1) Understanding of Instance variables and methods
2) Declaring constructors and using constructor to set the instance variables
3) Basic understanding of Encapsulation (data hiding and controlled access)
