JLauncher ☕🚀

A friendly, interactive launcher for Java applications on Windows.

Windows Java Batch PowerShell

✨ What is JLauncher? JLauncher is a unified launcher for Java applications on Windows, built using Batch Script, PowerShell, and a touch of VBS for sound effects. It provides a simple, user-friendly, graphical experience for selecting and running .jar files — no terminal knowledge required. Perfect for:

• Users who don’t want to type commands
• Developers distributing Java apps
• Anyone who wants a clean, automated way to run .jar files

✨ Features

• 🖱️ Interactive .jar selection via graphical PowerShell dialog
• 🌎 Automatic bilingual support (Portuguese 🇧🇷 / English 🇺🇸)
• 🌐 Optional URL launcher (e.g., open http://localhost:8080 after startup)
• 💾 Persistent configuration (remembers last selected JAR, URL, and delay)
• 📜 Execution logs stored in launcher.log
• 🎨 Console animations, banners, and color effects
• 🛑 Robust error handling (missing Java, missing JAR, cancellation, etc.)
• 🔊 Sound effects using VBS scripts
• ⚙️ Multiple launch modes (-s, -m, -b, etc.)

💡 Why JLauncher? Because not every user wants to type: java -jar myapp.jar

And because Java apps deserve a friendly launcher, not a cryptic command line.
