Question

Given the following constructor code,which of the statements are true? public Book(String ISBNOfBook,double priceOfBook,
Int numberOrderedOfBook)
{
If (ISBNOfBook == "")
Throw new BlankISBN();
If (priceOfBook < 0)
Throw new NegativePrice(priceOfBook);
If (numberedOrderedOfBook < 0)
Throw new NegativeNumberOrdered(numberOrderedv);
ISBN = ISBNOfBook;
Price = priceOfBook;
NumberedOrdered = numberOrderedOfBook;
}
A) There is an error: a throws clause should be added to the constructor header.
B) Classes extending the Exception class should be created for each of the custom exceptions that are thrown in the constructor.
C) The calling method must handle the exceptions thrown in the constructor,or have its own throws clause specifying them.
D) All of the above.

Quizplus · Accepted Answer

A is true because the constructor is throwing checked exceptions, so a throws clause should be added to the constructor header. 
B is true because in the constructor, two custom exceptions (BlankISBN and NegativePrice) are thrown, and to handle them properly, classes extending the Exception class should be created for each of them. 
C is also true because the calling method must either handle the exceptions thrown in the constructor or have its own throws clause that specifies them. Therefore, all of the above statements are correct.
