Question

Design and code a program including the following classes as well as a client class to test all the methods coded:A Passenger class, encapsulating a passenger. A passenger has 2 attributes: a name, and a class of service, which will be 1 or 2.
A Train class, encapsulating a train of passengers. A train of passengers has one attribute: a list of passengers, which must be represented with an Array List. Your constructor will build the list of passengers by reading data from a file called passengers.txt.

Write a client class to test all your methods in Train Class

Explanation / Answer

Note : Please specify your passenger.txt file path in constructor of train class

The current entry contains the path of my local system

==========================================

Class for Passenger.java

==========================================

public class Passenger {

   private String name;
   private String classOfService;
  
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public String getClassOfService() {
       return classOfService;
   }
   public void setClassOfService(String classOfService) {
       this.classOfService = classOfService;
   }
}

===============================================

Class for Train.java

===============================================

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

public class Train {

   private ArrayList<Passenger> passengersList;

   BufferedReader br = null;

   public Train() {
      
       //initializing passengers arrayList
       passengersList = new ArrayList<Passenger>();
      
       try {

           String sCurrentLine;
           //Please must modify the file path you have here
           //If you have windows the path will be like this example D:\passengers.txt
           //If you are using linux it will be /home/username/foldername/passengers.txt
           br = new BufferedReader(new FileReader("D:\passengers.txt"));

           //Reading data from passengers.txt make sure that your passenger info must be in name and followed by class of service in text file
           //and must be separated by space
           while ((sCurrentLine = br.readLine()) != null) {
               String[] passengerInfo = sCurrentLine.split(" ");
               if(passengerInfo.length==2) {
                   Passenger passenger = new Passenger();
                   passenger.setName(passengerInfo[0]);
                   passenger.setClassOfService(passengerInfo[1]);
                   //Adding one by one passenger to list
                   passengersList.add(passenger);
               }
           }
      
  
       } catch (IOException e) {
           System.out.println("File Not Found");
       }
   }

   public ArrayList<Passenger> getPassengersList() {
       return passengersList;
   }

   public void setPassengersList(ArrayList<Passenger> passengersList) {
       this.passengersList = passengersList;
   }

  
}

=================================================

Class for Client.java

=================================================

import java.util.ArrayList;

public class Client {

   public static void main(String[] args) {
      
       //Creating train object
       Train train = new Train();
      
       System.out.println("Passengers List");
       System.out.println("=======================================");
       System.out.println("Passenger Name Class of Service:");
       System.out.println("=======================================");
       ArrayList<Passenger> passengersList = train.getPassengersList();
       for(Passenger passenger:passengersList) {
           System.out.println(passenger.getName() +" "+passenger.getClassOfService());
       }
   }

}

======================================================

Output

=======================================================

Passengers List
=======================================
Passenger Name    Class of Service:
=======================================
Smith           1
Cook           2
Stefen           1
Warner           2
Hussy           1
Anderson           2
James           1

==========================================================

The file i have used for passengers.txt contains this

=====================================================

Smith 1
Cook 2
Stefen 1
Warner 2
Hussy 1
Anderson 2
James 1

==================================================================

Note: Please make sure that your passengers.txt also contains the same format, i mean name followed by class of service and seperated by space.
