📘 docs: Explain difference between constructors and methods in Java

🔑 Short Key: constructor-vs-method

🧠 Logic & Highlights:
- **Constructor**: special block to initialize objects, name matches class, no return type, invoked automatically with `new`
- **Method**: defines object behavior, can have any name, must have a return type, invoked explicitly

📝 Key Differences:
- Purpose: initialize object vs. perform actions
- Name: same as class vs. any name
- Return type: none vs. required
- Invocation: automatic vs. explicit
- Inheritance: not inherited vs. inherited/overridable
- Overloading: supported for both

📊 Added Comparison Table:
| Feature       | Constructor                        | Method                                |
|---------------|------------------------------------|---------------------------------------|
| Purpose       | Initialize object                  | Define behavior/operations            |
| Name          | Same as class                      | Any valid identifier                  |
| Return Type   | None                               | Must return type (`int`, `void`, etc.)|
| Invocation    | Auto on object creation            | Explicit call on object               |
| Inheritance   | Not inherited                      | Inherited and overridable             |
| Overloading   | Supported                          | Supported                             |

📘 Example:
- Created a `Car` class with parameterized constructor to set `model` & `year`
- Added `displayDetails()` method to show details
- Demonstrated usage in `Main` class

🎯 Learning Outcomes:
- Clear understanding of when and how to use constructors vs methods**
- Demonstrated real-world example with `Car` class.
