Question

Java Program:

Design a class “Book” with the data attributes title - String, author - String, yearPublished - integer and price - double. Write a parameterized constructor that initializes the attributes. Write accessor and mutator methods, and a print method that prints all of the attributes. In the main method, create a single object and give it values of your choice. Call the print method to print the values.

Sample Run:

The Book is:

The Art of Computer Programming

Donald Knuth

1968

178.04

Answer 1

public class Book {

    private String title;
    private String author;
    private int yearPublished;
    private double price;

    public Book(String title, String author, int yearPublished, double price) {
        this.title = title;
        this.author = author;
        this.yearPublished = yearPublished;
        this.price = price;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public int getYearPublished() {
        return yearPublished;
    }

    public void setYearPublished(int yearPublished) {
        this.yearPublished = yearPublished;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public void print() {
        System.out.println("The Book is:");
        System.out.println(title);
        System.out.println(author);
        System.out.println(yearPublished);
        System.out.println(price);
    }

    public static void main(String[] args) {
        Book book = new Book("The Art of Computer Programming", "Donald Knuth", 1968, 178.04);
        book.print();
    }
