Library class: Fields: books as arraylist to store all the books available in the library B3 B1 B2 В4 B5 Constructor: Library() } : No parameterized constructor to create the books object Methods: 1. addBook(Book bookobj): to add a new book to the arraylist; send the book object as a parameter to this method. 2. searchBook(String name): search a book by a given name in the arraylist. if exits print bookX found; otherwise print not found!!! 3. RemoveBook(String name): to delete a book object from arraylist by a given name: Hint: you need to use iterator class and remove method. Book class: Fileds: bookld, bookname. Constructor: two parameterized constructor that accepts name a parameter Book(int ID, String name) ..... Methods: 1. Accessor method to return the name of the book 2. Mutator method to change the id of the book. Use this Main method: in your program: public static void main(String args[]) { Library lib=new Library(); lib.addBook(new Book("b1")); lib.addBook(new Book("b2"));…

For example if user1 Selects a small pizza with the toppings, tomato and pepperoni and a crust type of thin crust. And user2 selects a medium pizza, with toppings, extra cheese and green peppers and a medium crust. How would I place these two orders into an Array List and then print them using the "Print All Orders"?
Project in Java programming language : Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.

Step1-Study the scenario below and create a Java Program for Builders Warehouse, The program must consist of a class called Materials to handle the details of the materials. The program should read the materials details from the material.txt file then use a LinkedList to store the material details. Then finally the products stored in the LinkedList must be displayed like the sample code below step 2-There must be clear code and a screenshot of the code running.
