Essential Class coding(C#)

Let`s declare a class named Cars.Remember each class contain fields,methods,sub-classes and more.
standard definition:access return type class
Access modifier is how the class will be accessed could be publicly,privately,protected....
public class Cars
{
//let`s declare some fields ,you can add more depending on your requirement.
public int ntires;
public bool sunroof=true;

//let declare a method

public void Start()
{
Console.WriteLine("Vooommm......");
}

Public void Stop()
{
Console.WriteLine("Stoppinnnnnnng.....");
}

//You could add Property,structs and more

} //end class Cars


//Now let create a class that will use all fields and methods of Cars class=INHERITANCE
//u use : in front of sub class like JapaneseCar

Public class JapaneseCar:Cars
{
//JapaneseCar class will inherit all fields,methods.... of Cars Class and can implement it own
//methods,fields....


}

//Let say i dont a sub class inherits a given class .The anwer is you need to seal the class you dont to be inherited with the keyword sealed
//Let create 2 classes:

public sealed class AllCars
{
//field,properties,methods...
}
public class ChineseCars :AllCars
{
/Putting a colon in front of ChineseCars will not work and generated error because
//AllCas class is sealed
}
