Q3. We have two classes, one is ClassA and other is ClassB, the ClassB inherit base class ClassA. If we make the object of child class ClassB then which class constructor called first?
Q4. We know that Base class constructor called first. But if we creating object with parameters, and base class have both constructor default and parameter, then which constructor of base class called first.
Q25. Why we use generics?
I hope it might help you! Thank you!
