Question

Write a class called Book that has the following attribures: copiesInStock yearOfPublication, isbn, price, title, publisher, author. This class will later be used in a test method to compile a listing of 10 Book objects of the same listed above. Write proper gets and sets to affect the values. Set the year of publication by default to 1900. Allow the user the option to enter values for ISBN, price and copiesInStock. If the user chooses to generate these values use Math.random() to randomly generate values for the ISBN to be in a format 9999-9999-9999-9999 (an acceptabel isbn might also appear as 2465-123-4523), copiesInStock not to exceed 100, price of a book not to exceed $100, and a year of publication to be not less than the year 1900 but no greater than the current year (1900-2012). Write 10 records of your book array type object you created that properly show this formatting, then dump your file to Console or JOptionPane. Math.random() hints souble someValue = 100 * Math.random() //100 is the upperlimit and //returns a double by default. This is also known as a "seed". //Sometimes called "seeding" a random number int someOtherValue = (int) (100 * Math.Random());
