The program, airline$\_$project.java, has been started for you and included with this assignment. The assignment will also use the data file, flights.txt$,$ which is also included with this assignment. The entire structure of the program has been created for you. The program contains stubs $($a method that runs, but does not do anything except run at the proper time$).$ Therefore, you must add the proper code to each method to perform the required actions listed below.

Flight information that must be defined in your main method is below. You must also add a count to keep track of how many flights were read in$.$ The data MUST be defined in the main method and passed to the methods that need them.

Flight number, Flight origination city, Flight destination city, Flight date, Flight time, Number of coach seats on flight, Cost of each coach seat, Number of first class seats on flight, Additional cost of first class seats

You must complete the methods as follows:

$$ start$\_$program$-$ This method will open the data file flights.txt and read flight information into a set of parallel arrays. ALL WORK required in other sections of the code is then performed on the parallel arrays. You will ONLY refer to the flights.txt data file in this start$\_$program method. The data file is stored with this assignment and must be copied into the main folder of your Java project. Please note that a copy of the data stored in the data file is included at the end of this assignment document for your info.

$$ print$\_$all$\_$info $$ This method will print all information that was read into the flight arrays

$$ print$\_$specific$\_$flight$\_$info$-$ This method will print all information on a specific flight. You will have to prompt the user for the flight number and search the arrays for the flight

print$\_$destination $$ This method will print all information on all flights going to a specific city. You will have to prompt the user for the destination city and search the arrays for the destination city

print$\_$total$\_$seats $$For each flight, this method will print the flight number and the destination of the flight along with the total number of seats on the flight $($coach $+$ first class seats$)$print$\_$seat$\_$value $$ For each flight, this method will print all information on the flight and calculate the value of the coach seats $($number of coach seats multiplied by the cost of the coach seats$)$ and the value of all the first class seats on the flight. $($A cost of one first class seat is the cost of the coach seat plus the additional cost that was read in$)$
