this is the objective i was given as well as the code i am running, posted way at the bottom. I am not getting the output that is asked which is to get all the reservations 815. If i input the whole text from the reservation text file I am getting all reservations when i just need the 815 ones. Not sure what I did wrong in my code if anyone can help me out please

These are the text flies that were given:

flight-schedule.txt

866,commercial,SAT,LAS,13:05,14:00 815,commercial,SAT,LAS,08:00,09:05 267,private,SAT,SLC,05:50,09:50 896,commercial,SAT,JFK,07:00,11:50 

Reservation.txt:

Objectives: Polymorphism ArrayList Strings, Comparable UML diagrams Task: Create a basic flight reservation program The local airport would like to display flight information for all flights that occur each day. Flight information includes the data about each flight (its destination, origin, arrival time, etc) as well as the reservations made for that flight. They keep this information in two [very disorganized] text files-your program will sort out the data and display it to the user Getting Started Your application will consist of 5 Java classes: Lab3.java . Flight.java CommercialFlight.java PrivateFlight.java Reservation.java It will read in data from two text files: fight-schedule.txt and reservations.txt. You will place these files at the top of your project in Eclipse that is, not within the source folder or any other folder. If this is done correctly, within your code, you will need only refer to the file name, rather than giving a full path to the location of each file Lab3.java This class will run your program (Hint: it must have a main method). The main method will have an ArrayList of flight- it will populate the data for these flights and their reservations from the text file (see below for additional details). When run, your program will read in the data from the given text files, and print exactly as follows
