🖥️ 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

✨ Difference between Abstraction and Encapsulation in Java ✨

1️⃣ Abstraction

Focus: Hides implementation details, shows only functionality.

How: Achieved using abstract classes & interfaces.

Example: You drive a car without knowing how the engine works.

2️⃣ Encapsulation

Focus: Hides data (fields/variables) by wrapping with methods.

How: Achieved using private variables & getter/setter methods.

Example: ATM machine hides your balance, lets you access via PIN.

👉 In short:

Abstraction → Hides “what” happens inside.

Encapsulation → Hides “how” data is accessed & modified.

Hello friends, great news!

I’ve created notes up to Java IO. Check them out here: https://smartprogramming.in/tutorials/

Your support motivates me!

It takes a lot of effort to create these notes for you all free of cost, so please provide your valuable feedback here :

🔑 Difference between Abstraction vs Encapsulation in Java

📌 1. Purpose
- Abstraction: Hides implementation details and shows only essential features.
- Encapsulation: Hides data by binding it with methods.

📌 2. Implementation
- Abstraction: Achieved using abstract classes & interfaces.
- Encapsulation: Achieved using classes, getters & setters.

📌 3. Focus
- Abstraction: Focuses on what to do (not how to do it).
- Encapsulation: Focuses on how to protect data from outside access.

📌 4. Example
- Abstraction: Car.start() – you just start, don’t know the internal mechanism.
- Encapsulation: private balance in a BankAccount class accessed via getBalance().

🚀 Hey Smart Developers! 👩‍💻👨‍💻

Java has released another Long-Term Support (LTS) version: Java 25 on September 16, 2025.

Here’s what’s new in Java 25:
- Faster Startup – Apps start quicker with smart profiling.
- Better Pattern Matching – Works with primitive types too!
- No psvm Needed – Run programs directly: System.out.println("Hello Developers!");
-Stronger Security – New key derivation API.
-Scoped Values & Flexible Constructors – Cleaner, safer code.

Java 25 = Faster ⚡.... Simpler 🧠 & More Fun 🧩 !

Happy Dussehra to all 🥳🌟

सत्य, सनातन, सदाचार और सकारात्मकता की शाश्वत विजय के पावन प्रतीक *महापर्व दीपावली* की हार्दिक बधाई एवं शुभकामनाएं!

प्रभु श्री राम और माता जानकी की कृपा से घरों के साथ हृदय भी आलोकित हों, जीवन में विश्वास, उत्साह और उमंग का दीप प्रज्वलित हो, यही प्रार्थना है।

जय जय सियाराम! 🙏🙏 🪔 🪔
