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"));…

StockList Class • This class will contain the methods necessary to display various information about the stock data. • This class shall be a subclass of ArrayList. • This class shall not contain any data fields. (You don't need them for this class if done correctly). • This class shall have a default constructor with no parameters. o No other constructors are allowed. • This class shall have the following public, non-static, methods: • printAllStocks: This method shall take no parameters and return nothing. ▪ This method should print each stock in the StockList to an output file. ▪ NOTE: This method shall NOT print the data to the console. The output file shall be called all_stock_data.txt. The data should be printed in a nice and easy to read format. o displayFirstTenStocks: This method shall take no parameters and return nothing. ▪ This method should display only the first 10 stocks in the StockList in a nice and easy to read format. ▪ This method should display the data in the…
