The third part: "39"$"39"$ is the title number for the book.

The fourth part: "6"$"6"$ is a check digit to indicate that the sum of the ISBN digits is 10.$10.$

The class should have a constructor and methods to set and get the ISBN as a string.

−$-$ setBookISBN: to set the ISBN for the book.

−$-$ getAuthor: to return the author of the book.

−$-$ setAuthor: to set the author of the book.

−$-$ getBookISBN: to get the ISBN of the book.
