Note Taking Application

JavaNote is a simple text-based note-taking application designed to help users create, organize, and manage their notes efficiently. With features like formatting, categorization, and basic search functionality, JavaNote provides a user-friendly interface for maintaining digital notes. This project is an excellent opportunity to practice Java programming and GUI development skills.

Key Features:

• User Authentication: Users can create accounts or log in securely to access their notes.

• Note Creation and Editing: Users can create new notes, edit existing ones, and apply basic formatting (such as bold, italic, and underline) using a user-friendly text editor.

• Categorization: Notes can be categorized into different topics or folders, allowing users to better organize their content.

• Search Functionality: Users can search for specific notes by keywords, titles, or tags.

• User Interface: A graphical user interface (GUI) will be provided for users to interact with the application. The GUI should include buttons, menus, and text areas for creating, editing, and managing notes.

• File Persistence: Notes and user data will be saved locally using file storage. Serialization can be used to save and load notes.

• Formatting Options: Implement a set of buttons or formatting shortcuts that users can use to apply formatting options to selected text in the note editor.

• Responsive Design: Design the application’s GUI to be responsive and user-friendly, ensuring that it works well on different screen sizes.

• Data Validation: Implement input validation to ensure that users enter valid data when creating or editing notes.
