📘 Project Title

Java Task Manager System Using Swing UI, Socket Programming, and Java Collections

---

🎯 Objective

The goal of this project is to build a modular, interactive task management application using core Java, that supports basic CRUD operations (Create, Read, Update, Delete) with:

• Client-Server architecture
• Graphical User Interface using Swing
• HashMap-based task storage (in-memory)
• Demonstration of OOP principles in action

---

🧑‍💻 Technologies & Tools Used

Technology / Tool	Purpose / Use
Java SE	Core language for entire application
Swing	Building the graphical user interface
Java Sockets	Enabling client-server communication
HashMap (Collection)	Storing and managing tasks in memory
BufferedReader / Writer	Reading and writing messages over the socket
NetBeans / IntelliJ / VS Code	IDEs for development
Command Line	Running server and client separately

⚙️ Functional Overview

Feature	Description
Add Task	Adds a new task with auto-incremented ID
View All Tasks	Displays all current tasks
Update Task	Edits title and description using task ID
Delete Task	Deletes task by ID
GUI Interface	Clean Swing UI for user interaction
Server	Console-based server runs separately and processes requests
Storage	Tasks stored in a HashMap<Integer, Task> object

---

🧠 OOP Concepts Applied

Concept	Description
Class	Each component is modeled as a class (e.g., Task, TaskStorage, TaskServer)
Object	Task is instantiated as objects from the Task class
Encapsulation	Fields are private, accessed via getters and setters
Abstraction	Logic hidden inside TaskStorage with methods like addTask, updateTask
Modularity	Clean separation of GUI, server, logic, and data model
Constructor & Overriding	Task constructor and toString() method override

---

✅ How to Run

1. Compile All Classes

   • Use IDE or run:

     javac */*.java

2. Start the Server First

   java server.TaskServer

3. Start the Swing GUI Client

   java client.SwingTaskClient

4. Interact Using GUI:

   • Add Task → title + description
   • Update Task → task ID + new title + new description
   • Delete Task → task ID
   • View Tasks → all tasks

---

📍 Use Case Scenario

• 🎓 Academic Projects: For learning GUI, Sockets, and OOP
• 💻 Standalone Desktop App: Can run without the internet or external DB
• 🧱 Foundation App: Can be extended to file-based or DB-based persistent task manager

---

🔮 Future Enhancements

• ☁️ Switch to persistent storage (File or JDBC database)
• 👤 Multi-user support with login system
• 🌐 RESTful API using Spring Boot for web UI or mobile apps
• 📅 Add deadline, category, tags, priority features
• 📦 Export/Import tasks via CSV/JSON
