Can constructor be overloaded yes or no?

Since the constructors can’t be defined in derived class, it can’t be overloaded too, in derived class .

Yes, a Class in ABL can have more than Constructor . Multiple instance constructors can be defined for a class that are overloaded with different parameter signatures. If an instance constructor is defined without parameters, that constructor becomes the default instance constructor for the class.

The constructor overloading can be defined as the concept of having more than one constructor with different parameters so that every constructor can perform a different task .
