🧩 Task Manager App

A simple yet efficient console-based task management application built with Java 17.
It allows users to add, update, remove, list, and export tasks, while automatically saving changes locally.

---

🚀 Project Overview

The Task Manager App provides an interactive CLI for managing daily tasks.
All operations are reflected in a local file (tasks.txt), and users can export their task list in Markdown format (tasks.md).

The project demonstrates:

• File handling in Java (FileHandler)
• Object-oriented design (Task, TaskManager)
• Data persistence (via text files)
• Markdown report generation
• Unit testing using JUnit 5
