feat: Add Shoes class with getters and setters for size and color

WHAT the code does:
- Defines a `Shoes` class with private attributes:
  - `size` (int)
  - `color` (String)
- Provides **setters** (`setSize`, `setColor`) to modify attributes.
- Provides **getters** (`getSize`, `getColor`) to access attributes.
- `main()` demonstrates:
  - Creating a `Shoes` object for brown moccasins (size 31).
  - Creating another `Shoes` object for black boots (size 32).
  - Printing descriptions using getters.

WHY this matters:
- Demonstrates **encapsulation**: private fields exposed via getters and setters.
- Shows how to create and manipulate multiple object instances.
- Reinforces object-oriented thinking: each object holds its own state.

HOW it works:
1. `moccasins` object → `color = brown`, `size = 31`.
2. `boots` object → `color = black`, `size = 32`.
3. Prints:
   - `"I have moccasins size 31"`
   - `"I also have black boots."`

Tips & gotchas:
- Getters/setters follow JavaBean conventions → useful for frameworks and libraries.
- Could add validation (e.g., `size > 0`) inside setters.
- Overriding `toString()` would allow simpler object display without manual string building.
- Fields are mutable — consider immutability if values should not change once set.

Use-cases:
- Modeling products in an e-commerce or inventory system.
- Teaching encapsulation and object property access in Java.
- Extendable to include brand, price, or material.
- Serves as foundation for **POJOs** (Plain Old Java Objects).
