Answer to Question #239019 in Java | JSP | JSF for Jaden

Question

1 When the user selects to view a report, display the product report generated from the arrays in your application. You must create a class called ReportData which will contain get and set methods for each item required in the report

Answer 1

The program answering this question is based on a bookshop

. it gives a report of the books available in Dkay bookshop, the book title, the author, number of copies available for sale and the number of copies sold and this data is stored in arrays. We have getters and setters methods and also a method for printing in the ReportData class.

import java.util.Scanner;
 class ReportData {
     // private = restricted access
    private String book_name;
    private String book_author;
     private String copies_available;
     private String copies_sold;
     //private int num_of_products;

     // Setters
     public void setbook_name(String b_name) {
         this.book_name = b_name;
     }
     public void set_author(String ar_name) {
         this.book_author = ar_name;
     }
     public void setCopies_available(String cpa_code) {
         this.copies_available = cpa_code;
     }
     public void setCopies_sold(String cps_code) {
         this.copies_sold = cps_code;
     }
     // Getters
    public String getBook_name_name() {
        return book_name;
    }
     public String getBook_author() {
         return book_author;
     }
     public String getCopies_available() {
         return copies_available;
     }
     public String getCopies_sold() {
         return copies_sold;
     }
     //Method for printing the details of the products
     public void printDetails() {
         System.out.println("\tBook Name: " + book_name);
         System.out.println("\tBook Author: " + book_author);
         System.out.println("\tCopies available for sale: " + copies_available);
         System.out.println("\tCopies sold : " + copies_sold);


     }



 }

public class Main {

    public static void main(String[] args) {
        //An array listing the books available in my stock for sale, the copies available,
        // copies sold, author and book name
        String[][] books_for_sale = {
                {"Don Quixote", "Miguel de Cervantes", " 1345", "5076"},

                {"The Hobbit","J.R.R. Tolkien","5678","8893"}
        };
        //Menu
        System.out.println("Dkay Bookshop stock management");
        System.out.println("1.View report of your stock");
        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<books_for_sale.length;i++)
            {
                System.out.print(i+1);
                ReportData myObj = new ReportData();
                myObj.setbook_name(books_for_sale[i][0]);
                myObj.set_author(books_for_sale[i][1]);
                myObj.setCopies_available(books_for_sale[i][2]);
                myObj.setCopies_sold(books_for_sale[i][3]);

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