|
||
|
||
## Introduction
|
||
|
||
- A programming paradigm
|
||
- Allows:
|
||
- Model objects
|
||
- Make objects interact with each other
|
||
- Objcts refer to complex variables
|
||
|
||
## Benefits and motivation
|
||
|
||
- Modularity
|
||
- Abstraction
|
||
- Productivity and reusability
|
||
- Security and encapsulation
|
||
|
||
## Concrete example
|
||
|
||
- When we develop a game with cars inside
|
||
- We develop the car one time and all other games can re-use the base of the car that we created
|
||
- We have access to characteristics
|
||
- Model
|
||
- Color
|
||
- Fuel type
|
||
- ...
|
||
- We also have the behavior of the car
|
||
- Start
|
||
- Accelerate
|
||
- Stop
|
||
|
||
## Object
|
||
|
||
- Data part: object characteristcs
|
||
- Attributes
|
||
- Properties
|
||
- Fields
|
||
- ...
|
||
- Code part = oject behavior
|
||
- Methods
|
||
- Procedure
|
||
|
||
## Class
|
||
|
||
- Object = classs instance
|
||
- Class
|
||
- New data type
|
||
- Collection of objects
|
||
- Figuratively
|
||
- Class = mold
|
||
- Object = cake
|
||
- Class at compilation VS object at runtime
|
||
|
||
```csharp
|
||
public class MyFirstClass {
|
||
public MyFirstClass() {} //constructor
|
||
}
|
||
MyFirstClass c = new MyFirstClass(); //new object
|
||
```
|
||
|
||
## Modelization
|
||
|
||
- First mandatory step
|
||
|
||
- Data modeling
|
||
|
||
- UML: Unified Modeling Language
|
||
|
||
- Class diagram
|
||
- Class Diagram example:
|
||
|
||
- Code example:
|
||
|
||
```csharp
|
||
public class MuFirstCar {
|
||
private string _color;
|
||
public string GetColor(){
|
||
return _color;
|
||
}
|
||
public void SetColor(string color){
|
||
_color = color;
|
||
}
|
||
}
|
||
```
|
