Question

After execution of the following code, what are the declared type (static type) and the object type (dynamic type) of nCopy?

NaturalNumber n = new NaturalNumber1L();

NaturalNumber nCopy = new NaturalNumber2(n);

Group of answer choices

Declared type is NaturalNumber, object type is NaturalNumber1L.

Declared type is NaturalNumber2, object type is NaturalNumber1L.

Declared type is NaturalNumber, object type is NaturalNumber2.

Declared type is NaturalNumber2, object type is NaturalNumber.

Answer 1

Answer #1

Answer

c)
Declared type is NaturalNumber, object type is NaturalNumber2.

because nCopy is declared as NaturalNumber and object of NaturalNumber2 is assigned to that variable
