Question

using java

Develop the classes and interface represented in the following UML diagram: <cinterface >> Passenger 1 String name has passengers String getNamel) String getFaro Typel) String getName() void display Passengers Person String frame String last Name intage Note that the Person class includes both a first and last name, but the Passenger interface requires a full name. The field fare Type is determined by a passenger's age: "Regular fare is the full fare, "Youth" is a reduced fare for children under the age of 18, and Senior is a reduced fare for people over the age of 65. Add necessary features suggested for the Train class such as a name for a train and a method to display the names of the train passengers. Include a field and method for the required association. Add a method called displayPassengers that lists the names of those passengers. Include methods/fields/constructors as required. Develop a TrainDriver class to test your code. You must add (hardcode) several passengers to the train list (all fare types should be illustrated). Display the train name and passenger list using the displayPassengers() method Sample output: Train name: Hogwarts Express Passengers: Youth Harry Potter Youth Hermione Granger Youth Ron Weasley Youth Ging Regular Remus Lupin

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

// Passenger.java
public interface Passenger {
String getName();
String getFareType();
}

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

// Person.java

public class Person implements Passenger {
private String firstName;
private String lastName;
private int age;
  
   /**
   * @param firstName
   * @param lastName
   * @param age
   */
   public Person(String firstName, String lastName, int age) {
       this.firstName = firstName;
       this.lastName = lastName;
       this.age = age;
   }

  
   @Override
   public String getName() {
       return firstName+" "+lastName;
   }

   @Override
   public String getFareType() {
       String str="";
       if(age<18)
       {
           str="Youth";
       }
       else if(age>=18 && age<=65)
       {
           str="Regular";
       }
       else
       {
           str="Senior";
       }
       return str;
   }
  

}

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

// Train.java

import java.util.ArrayList;

public class Train {
private ArrayList<Passenger> passengers;
private String name;
   /**
   * @param passengers
   * @param name
   */
   public Train(String name) {
       this.passengers = new ArrayList<Passenger>();
       this.name = name;
   }
  
   public String getName()
   {
       return name;
   }
   public void displayPassengers()
   {
       System.out.println("Passengers :");
       for(Passenger p: passengers)
       {
           System.out.println(p.getFareType()+"\t"+p.getName());
       }
   }
   public void addPassenger(Person p)
   {
       passengers.add(p);
   }

}

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

// TrainDriver.java

public class TrainDriver {

   public static void main(String[] args) {

       Train t = new Train("Hogwarts Express");
       t.addPassenger(new Person("Harry", "Potter", 14));
       t.addPassenger(new Person("Hermlone", "Granger", 16));
       t.addPassenger(new Person("Ron", "Weasley", 12));
       t.addPassenger(new Person("Remus", "Lupin", 67));

       System.out.println("Train Name :" + t.getName());
       t.displayPassengers();

   }

}

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

output:

Train Name :Hogwarts Express
Passengers :
Youth   Harry Potter
Youth   Hermlone Granger
Youth   Ron Weasley
Senior   Remus Lupin

=====================Could you plz rate me well.Thank You
