Behaviour During Construction and Destruction
Languages differ in their behaviour while the constructor or destructor of an object is running. For some languages, notably C++, the virtual dispatching mechanism has different semantics during construction and destruction of an object. While it is recommended that virtual function calls in constructors should be avoided for C++, in some other languages, for example C# and Java, the derived implementation can be called during construction and design patterns such as the Abstract Factory Pattern actively promote this usage in languages supporting the ability.
