How is this written in Java programming language?

CSCI 3200 Assignment 4 100 points Due date: Thursday, Sept. 28 (before class) In this assignment, you will write a program to simulate an inquiry system of a small library. The program should operate as follows: 1. Read the library catalog from an input data file. The data file should be named catalog.txt. There is one input line per book, and these lines have the following format: -book id> is a 5-digit positive integer (you may assume the leftmost digit is not a zero), is a string of at most 30 characters with no embedded blanks (you can use""in between words in a title), is a string of 10 digits, is a string of at most 10 characters, and is a character ('F' if the book is fiction; 'N' if it is a non- fiction book). You may assume the catalog has no more than 100 books (a small library). A sample catalog is shown at the end of the specification. Make sure to include exception handling code related to file input. 2. Read from standard input a customer's inquiry with a given book_id and output the complete information of the book. Your program should allow the customer to continue to inquiry about other books. When a zero input for -book id- is entered, it means the end of the customer's inquiry The output should include the book id, book_title, ISBN, author_last name, and "Fiction" or Non-Fiction" for category, printed on a single line. A sample output is shown at the end of the specification. 3. Exception handling: The following error is possible and should be handled by your program not found. You need to define a BookNotFoundException and handle it by writing an error message. This should be defined as a checked exception. It should include two constructors. One is the default constructor, and the other is one-parameter constructor and the parameter type is String. Program Structure: Your source code should be developed in three files: Book.java, BookDemo.java, and BookNotFoundException.java. Book,java will contain the class definition for a book according to the requirements specified below. BookDemo java will be the application program that runs the simulation of the inquiry. BookNotFoundException java will define the checked exception
