Update Add_old_books.java

[aryan735]

The AddOldBooks application is a Java Swing-based graphical user interface (GUI) designed for users to add details of old books into a system. The application offers a straightforward way to enter book-related information and ensures that users can easily submit the data while maintaining an intuitive and visually appealing layout.

Features:

Enhanced User Input Fields:

Book Name: Now uses a JTextField to allow users to input the name of the book. This field is more appropriate for single-line text input compared to JTextArea. Writer's Name: Replaced JTextArea with JTextField for entering the writer's name, streamlining the input process. Condition: The condition is pre-set to "Old" with radio buttons disabled, indicating that the application is focused on old books. Published Date: Users can select the publication date using three dropdowns for day, month, and year. This feature provides a clear and structured way to enter date information. Subject: Dropdown list (JComboBox) allows selection from various subjects (e.g., English, Maths, Chemistry), making it easy to categorize the book. Publisher Name: Changed to a JTextField for entering the publisher's name, enhancing the user experience for single-line input. Price (INR): Input field for entering the price of the book in Indian Rupees, now using JTextField. Source: Input field for specifying the source of the book, also using JTextField. Layout and Design Improvements:

GridBagLayout: Utilized for a more flexible and adaptive arrangement of components. This layout manager allows for a responsive and well-organized GUI. Consistent Styling: Uniform font styles and sizes across components enhance readability and provide a cohesive appearance. Functionality Enhancements:

Form Submission: The "Add" button triggers a confirmation dialog asking the user if they are sure about adding the book. Upon confirmation, the application performs validation checks. Validation: Ensures that all required fields (book name, writer's name, source, price, and publisher) are filled before the book is added. If any required field is empty, the application alerts the user to complete all fields. User Feedback: Provides clear and concise feedback through JOptionPane dialogs. Successful addition of a book is confirmed with a success message, and missing information prompts the user to fill out all required fields. Code Enhancements:

Refactored Code: The code has been refactored to improve readability and maintainability. Methods and components are better organized. Simplified Input Handling: Replaced JTextArea with JTextField for single-line inputs, making the form more intuitive. Improved Validation: Enhanced validation to ensure that all required fields are filled before proceeding with the addition of a book. Enhanced Layout Management: Employed GridBagLayout to create a responsive and well-aligned interface, improving the overall user experience. Usage:

Users can launch the application to fill out the form with details of an old book. Upon clicking the "Add" button, they will be prompted to confirm the addition. If all required fields are properly filled, the application will display a success message; otherwise, it will prompt users to complete the missing information.
