🎮 OOP GUI Projects

This repository contains three GUI-based Java projects built as part of my Object-Oriented Programming (OOP) course. All projects use Java AWT for the user interface and demonstrate various OOP principles through interactive games and applications.

📁 Projects Overview

1. 🚪 Guessing Treasure hunt

A fun door-guessing game where the player has 3 lives to find the hidden treasure behind one of three doors.
Twist: After each wrong guess, the treasure randomly changes its position to another door, making it more challenging.

• ☑ 3 doors to pick from
• ☑ 3 chances (lives)
• ☑ Random shifting treasure logic
• 💡 Uses Java AWT components like Button, Label, Frame, and Random

2. 📱 Phone Book Manager (with Edit Distance)

A simple contact management app that allows users to:

• 🔍 Search names using approximate matching via edit distance
• ➕ Add new contacts
• ✏️ View best-matching suggestions even with typos

This project demonstrates string manipulation and basic algorithms like Levenshtein Distance in a GUI environment.
