Problem with TestCars1 example

[NikolaJacques]

Type of issue

Typo

Description

I am not 100% sure but I think there might be a problem in the documentation.

The 'TestCars1' example provided in the documentation has the following line of code:

ConvertibleCar car2 = new ConvertibleCar(); 

The explanation given in the article is that due to the use of the 'new' modifier in the derived class, invocation of 'ShowDetails' calls the method in the base class (Car), not the derived class (ConvertibleCar). However, this is not consistent with the code above. Instead, the code should read as:

Car car2 = new ConvertibleCar();
