🎯 Project Overview

I’m excited to share my latest project — Typing Test Application, a desktop-based Java GUI project designed to help users practice and improve their typing speed and accuracy. Whether you're preparing for a job test, improving your typing skills, or just having fun, this tool is for you.

This app is fully developed using Java Swing, featuring a clean and interactive interface that calculates your Words Per Minute (WPM), accuracy, and typing time in real-time.

💡 Key Features

✅ Sensor-Free, Simple & Functional
✅ Random Paragraph Generator — Provides a new paragraph each time for diverse practice.
✅ Real-Time Statistics — Displays Timer, Accuracy, and WPM as you type.
✅ Overflow Alert — Automatically stops when paragraph is fully typed.
✅ Previous Results Panel — Stores your last test results for comparison.
✅ User-Friendly UI — Modern dark theme with rounded buttons and responsive layout.
✅ Restart Option — Restart anytime with one click.
