Inheritance with two Children?

[Rik Ny]

If I have an abstract class with two children, then how do I create an object of each of the children from the driver??
Cheers,

Child1 child1 = new Child1();
Child2 child2 = new Child2();
or
Abstract child1 = new Child1();
Abstract child2 = new Child2();
??
