Ποια η ροή του κώδικα εδω? :S εχω χασει λιγο τον μπούσουλα...

Owing to constructor chaining , when object of child class DemoChild is created , constructor Demo() of the parent class is invoked first and later constructor DemoChild() of the child is created.

αλλα δεν καταλαβαινω γιατι γινεται αυτο.
