NotesApp — Java File-Based Notes Manager

A lightweight, menu-driven Java application for creating and viewing personal notes from the terminal. Notes are appended to a local notes.txt file, so entries remain available between runs as long as the file is kept.

Features

• Add a note through a console prompt
• View saved notes in the terminal
• Append notes to notes.txt without overwriting previous entries
• Handle a missing notes file with a user-facing message
• Practise Java file I/O, exception handling, loops, and console input

Technology

• Java / JDK
• Scanner for console interaction
• FileWriter and BufferedReader for file-based storage

Requirements

Install a JDK and confirm that java and javac are available from your terminal.

Run locally

git clone https://github.com/kandisaikishore/NotesApp.git
cd NotesApp
javac NotesApp.java
java NotesApp

Choose 1 to add a note, 2 to view saved notes, or 3 to exit. The file notes.txt is read or created relative to the directory from which the program is launched.

Validation ideas

Check adding multiple notes, viewing an empty or populated file, restarting the application, and entering invalid menu input. The current menu parses the choice as an integer, so non-numeric input should be handled in a future improvement.

Roadmap

• Validate menu input without terminating unexpectedly
• Add search and delete functionality
• Support note timestamps or categories
• Add automated tests with a standard Java test framework

REST API and browser UI

The browser interface now calls a Java Spring Boot REST API. Install JDK 17+ and Maven, then start the API from the repository root:

cd api
mvn spring-boot:run

Open the UI at http://localhost:8082/. The API uses port 8082. API endpoints are under /api. Current API data is held in server memory and resets when the process restarts; configure a database before production use. The API module is separate from the original console/Swing classes, so it does not share their in-process state.
