You need to program a simple book library system. There are three java classes Book.java // book object class Library.java //library class A2.java //for testing The Book.java class represents book objects which contain the following fields title: a string which represents the book title. author: a string to hold the book author name year: book publication year isbn: a string of 10 numeric numbers. The book class will have also 3 constructors. -The default no argument constructor - A constructor...
MUST BE WRITTEN IN C++ Objective: Learn how to define structures and classes, create and access a vector of structures, use sort with different compare functions. Assignment: Your program will use the same input file, but you will print the whole book information, not just the title. And, most importantly, this time you will take an object oriented approach to this problem. Detailed specifications: Define a class named Collection, in which you will define a structure that can hold book...

C++ In this homework, you will implement a single linked list to store a list of computer science textbooks. Every book has a title, author, and an ISBN number. You will create 2 classes: Textbook and Library. Textbook class should have all above attributes and also a "next" pointer. Textbook Туре String String String Attribute title author ISBN Textbook* next Library class should have a head node as an attribute to keep the list of the books. Also, following member...
Using C++ Skills Required Create and use classes Exception Handling, Read and write files, work vectors. Create Functions, include headers and other files, Loops(while, for), conditional(if, switch), datatypes, etc. Assignment You work at the computer science library, and your boss just bought a bunch of new books for the library! All of the new books need to be cataloged and sorted back on the shelf. You don’t need to keep track of which customer has the book or not, just whether...
Each question needs a screenshot of the result and the code. insert appropriate amount of comments in the code. Exercise-1: Plant class. Define a class Plant that satisfies the spec below. Hints A. For this problem, provide an implementation for the Plant spec below, and test it using the example calls provided B. Although the constructor is described in the spec (and called) using the name Plant), the internal name for a class's constructor is_init__(). (There are two underscores before...
Implement the classes in the following class diagram. The Book class implements the Comparable interface. Use implements Comparable<Book> in the class definition. Now, all book objects are instances of the java.lang.Comparable interface. Write a test program that creates an array of ten books. 1. Use Arrays.sort( Book[]l books) from the java.util package to sort the array. The order of objects in the array is determined using compareTo...) method. 2. Write a method that returns the most expensive book in the...
Create a Python file (book.py) that has a class named Book. Book class has four attributes, title (string), author(string), isbn(string), and year(int). Title - the name of the book. Author - the name of the persons who wrote the book. ISBN - is a unique 13 digit commercial book identifier. Year - the year the title was printed. Your class should have the following methods: (1) __init__(self, title, author, isbn, year): This method called when an object (book) is created...

Complete the function load_trees_from_file() specified in A1.py It should take as a parameter the name of a file containing a set of trees and return a list containing instances of the Tree class representing all of the trees listed in the file. If the file does not exist, it should print that the file is not found and return None. You will need to include your Tree class definition from Question 1 in your answer. Consider the following code fragment:...
