🤖 5 Interesting Facts About Java ☕
1️⃣ Arrays in Java are 🧱 objects, even if they store primitives.
2️⃣ You can use underscores _ in numbers for readability 👉 1_000_000.
3️⃣ null can be cast to any 🧩 reference type, but using it throws a NullPointerException ❗
4️⃣ Enums are like full 🚀 classes – they can have constructors, methods & fields.
5️⃣ final variables can be left uninitialized but must be set later (e.g., in a constructor) ✅

🖥️ Types of Applications we can create in Java:
1. 📟 Console Applications – Text-based apps using terminal/command line
2. 🖼️ Desktop Applications – GUI apps using JavaFX/Swing (e.g., Notepad clone)
3. 🌐 Web Applications – Server-side apps using JSP, Servlets, Spring Boot
4. 📱 Mobile Applications – Android apps using Java with Android SDK
5. 🏢 Enterprise Applications – Large-scale apps using Java EE (e.g., Banking systems)
6. 🎮 Game Development – 2D/3D games using LibGDX or similar libraries
7. ☁️ Cloud-Based Applications – Scalable apps deployed on AWS, Azure, etc.
8. 🤖 IoT Applications – Smart device control using Java ME
9. 📊 Big Data Applications – Data processing using Hadoop in Java
10. 🧪 Scientific Applications – Simulations, heavy calculations in science
