## 🚀 Features

- Set alarm in **Minutes** or **Seconds**  
- Live countdown display (`MM:SS` format)  
- Plays a **WAV file** when time is up  
- Modern blue UI using **Swing + GridBagLayout**  
- Works on **Windows, macOS, and Linux**

## 🧩 How It Works

The app uses two timers:
1. `javax.swing.Timer` — updates the countdown label every second  
2. `java.util.Timer` — triggers the alarm after the specified delay  

When time is up:
- Plays `alarm.wav` using Java Sound API  
- Displays an alert dialog message  
- Resets for the next alarm
