Inheritance - Booking Tickets
Whether you fly for business or leisure purposes, you can choose either private jets or commercial airlines to get from point A to point B.
The task is to get the flight details and display them. Write a Java program to Implement this task.
[Strictly adhere to the Object-Oriented Specifications mentioned in the problem. Use the same Class names, attribute names, and method names specified here. Use appropriate naming conventions for getters and setters. Create all classes in separate files.]
Consider a class Aircraft
Include the following protected data members/attributes:
| Data Type | Variable Name |
| String | aircraftName |
| String | source |
| String | destination |
Include getters/ setters.
Include the following public methods
Prototype for the Parameterized Constructor,
public Aircraft(String aircraftName,String source,String destination)
Include the following method.
| Method Name | Description |
| void display() | The return type of this method is void, this method prints the details of the Aircraft |
Consider a class PublicAircraft that extends Aircraft
Include the following private attributes/data members:
| Data Type | Variable Name |
| Boolean | checkInBeforeTwoHours |
| int | noOfKgsAllowed |
| Double | additionalFeePerkg |
Here checkInBeforeTwoHours is a Boolean value that says whether the passenger should check-in before two hours or not.
This flag is true in the case of PublicAircraft.
Include getters/ setters.
Include the following public methods
Prototype for the Parameterized Constructor,
public PublicAircraft(String aircraftName,String source,String destination,Boolean checkInBeforeTwoHours ,int noOfKgsAllowed,float additionalFeePerkg)
Include the following method.
| Method Name | Description |
| void display( ) | This method prints the details of the booking done for the Public aircraft |
Consider a class PrivateAircraft that extends Aircraft
Include the following private attributes:
| Data Type | Variable Name |
| Boolean | checkInBeforeTwoHours |
| String | pilotPreference |
| String | purpose |
Here checkInBeforeTwoHours is a Boolean value that says whether the passenger should check-in before two hours or not.
This flag is false in the case of PrivateAircraft.
Here, pilot preferences is a string for which the name of the pilot should be given by the passenger according to his preference.
Purpose is a string that indicates the purpose of the flight (Medical,Personal,Cargo)
Include getters/ setters.
Prototype for the Parameterized Constructor,
public PrivateAircraft(String aircraftName,String source,String destination,Boolean checkInBeforeTwoHours,String pilotPreference ,String purpose )
Include the following method.
| Method Name | Description |
| void display( ) | This method prints the details of the booking done for the Public aircraft |
Consider a Main class to test the classes defined above.
