Answer to Question #203799 in Java | JSP | JSF for kumsal

Question

(with GUI) developed with Java programming language.

Create a project named “FavoriteBooks” which keeps a list of the books that a user has read and liked.

This list is stored in a text document (.txt) file and for each book it keeps the following data separated by a comma (,):Book id, Title, Category, First Author Name and Surname, Award Winner, Rating, Year, Number of Pages, and Short Description.

A login JFrame Form:

Functions:

1. Add a Book to the list with the given book id from a JTextField.

2. Delete a Book from the list with the given book id from a JTextField. This task should delete the book with the given id from the text document. A message dialog box should be displayed to show that this task is completed.

3. Display the information of a book with the book title given fully or as a keyword from a JTextField..

Note: How you design the GUI (Graphical User Interface) of your project is optional.
