The fleet class includes a constructor that creates an array to store the entire fleet of Delta airlines. It also had method to read and write files, sort the array by registration number, add and remove aircraft, display the fleet and maintenance lists, update aircraft miles and maintenance , and display information about specific aircraft. Could you please explain it in Java?

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
The fleet class includes a constructor that creates an array to store the entire fleet of Delta airlines. It also had method to read and write files, sort the array by registration number, add and remove aircraft, display the fleet and maintenance lists, update aircraft miles and maintenance , and display information about specific aircraft. Could you please explain it in Java?

Instance Variables
An array that stores Aircraft that represents Delta Airlines entire fleet
A variable that represents the count for the number of aircraft in the fleet
Methods:
o Constructor-One constructor that instantiates the array and sets the count to aero
readFile()-This method accepts a string that represents the name of the file to be
read. It will then read the file. Once the data is read, it should create an aircraft and
then pass the vehicle to the addAircraft method. It should not allow any duplication
of records. Be sure to handle all exceptions.
o writeFile()-This method accepts a string that represents the name of the file to be
written to and then writes the contents of the array to a file. This method should
call a sort method to sort the amay before writing to it.
sortArray()-This method returns a sorted array. The array is sorted by registration
number.u
addAircraft- This method accepts an aircraft and adds it to the fleet(the array only
if it is not already in the list.
displayFleet)-This method outputs all of the ships and shuttles that are in the fleet.
o display Maintenancetist()-This method outputs all aircraft in the array that currently
require maintenance, either by miles or date.
o displayNextMaintenancetist() This method outputs all aircraft in the fleet by
name, manufacturer, model, next maintenance date, and next maintenance miles
o updateMiles) This method accepts a regNumber and miles and updates the total
miles for the designated aircraft based on regNumber
update Maintenance()- This method accepts a regNumber and changes the
lastMaintenance date to the current date and resets last maintenance mileage
Transcribed Image Text:o display Aircraft()- This method accepts a regNumber and searches the array for an
aircraft that matches that regNumber and displays the information about that
vehicle.
o removeAircraft()- This method accepts a regNumber and searches the array for that
aircraft. For each item that doesn't match, it will copy the contents to the new
array. It will not copy the contents of the aircraft that is found. In other words, all
aircraft in the array will be moved up a position to fill in the gap in the array.
