Answer to Question #241932 in Java | JSP | JSF for doeboy

Question

Your application must make use of concepts such as arrays, loops, inheritance, constructors
and information hiding. Output must be shown in the form of a report using the console.
In your solution, make use of as many concepts, and components dealt with in this course, but
pay special attention to the following learning units:
• Learning Unit 1: Advanced arrays.
• Learning Unit 2: Introduction to inheritance

Answer 1

The answer provided is a part of registration system where a user can view the registration

details for all the students. It makes use of advanced arrays and inheritance as per requirements of the question.

package com.company;

import java.util.Scanner;

// Base Class Vehicle
class Person{

    // Private Fields
    private String first_name;
    private String middle_name;
    private String last_name;
    private String year_of_birth;



    // Parameterized Constructor
    public Person(String first_name, String middle_name, String last_name, String year_of_birth) {
        this.first_name = first_name;
        this.middle_name = middle_name;
        this.last_name = last_name;
        this.year_of_birth = year_of_birth;
    }

    // public method to print details
    public void printDetails() {
        System.out.println("\t\tFirst name: " + first_name);
        System.out.println("\t\tMiddle name: " + middle_name);
        System.out.println("\t\tLast name: " + last_name);
        System.out.println("\t\tYear of birth: " + year_of_birth);

    }

}

// Derived Class Car
class Student extends Person {

    // Private field
    private String registration_number;
    private String program;

    // Parameterized Constructor
    public Student(String first_name, String middle_name, String last_name, String year_of_birth,
                   String registration_number,  String program) {
        super(first_name, middle_name, last_name, year_of_birth);  //calling parent class constructor
        this.registration_number = registration_number;
        this.program = program;
    }

    public void StudentDetails() {  //details of car
        printDetails();         //calling method from parent class
        System.out.println("\t\tRegistration number: " + registration_number);
        System.out.println("\t\tProgram : " + program);
    }

}

class Main {

    public static void main(String[] args) {
        //An array to store the data of cars available for sale
        String[][] students_registration = {

        };
//MEnu
        System.out.println("\nWelcome to Havard university registration sysytem\n");
        System.out.println("1.View all the students registration details");
        System.out.println("2.Exit the program");
        System.out.print("Enter your option: ");
        Scanner sc = new Scanner(System.in);
        int option = sc.nextInt();
        if(option == 1)
        {

            for(int i = 0; i<students_registration.length;i++)
            {
                System.out.print(i+1);
                Student my_student = new Student(students_registration[i][0],students_registration[i][1],
                        students_registration[i][2], students_registration[i][3], students_registration[i][4],
                        students_registration[i][5]); //creation of car Object
                my_student.StudentDetails(); //calling method to print details
            }
        }

        else if(option==2)
        {
            System.out.println("Program exited successfully");
        }
        else
