feat: Perform addition using encapsulated methods in Add class [oop-addition-basic]

🔑 Key: oop-addition-basic
🧠 Logic:
- Designed a class `Add` that encapsulates input, processing, and output:
  • `getData()` → reads two integers `a` and `b` from user input.
  • `getTotal()` → calculates sum of `a + b` and stores it in `total`.
  • `showData()` → prints the result to console.
- Class `ClAdd` serves as the **driver** which creates an object of `Add` and sequentially calls its methods.

📌 Concepts Demonstrated:
- ✅ **Object-Oriented Programming** principles:
   • **Encapsulation**: data and logic grouped in methods inside a class.
   • **Modularity**: each method performs a distinct task (input, process, output).

- ✅ **Scanner class usage** for runtime input.

🧪 Flow of Execution:
1. `Add a = new Add();` → Object creation.
2. `getData()` → Prompts user and accepts input.
3. `getTotal()` → Computes `a + b`.
4. `showData()` → Displays the result.

📎 Use Cases:
- This is a basic template for understanding class-based design and separating logic for clarity and reusability.
