Explain the sequence of constructors that will be called when you create an object that is an instance of a derived class.
What will be an ideal response?
When you create any object, you are calling a class constructor method that has the same name as the class itself. For example:
SomeClass anObject = new SomeClass();
When you instantiate an object that is a member of a derived class, you call both the constructor for the base class and the constructor for the extended, derived class. When you create any derived class object, the base class constructor must execute first; only then does the derived class constructor execute. When you create any object, you always implicitly call the Object constructor because all classes are derived from Object. So, when you create a base class and a derived class, and instantiate a derived class object, you call three constructors: one from the Object class, one from the base class, and one from the derived class.
