1. Write program, WriteData. java, that writes the following data to file books. txt. Include the semicolons. Fiction;Abraham Lincoln Vampire Hunter;Grahame-Smith;Wiley;NY;13.99 ;222 Fiction;Frankenstein;Shelley;Presco tt;GA;7.99;321 NonFiction;Life of Kennedy;Jones;Pearson;MT;12.90;biog raphy Fiction;Dracula;Stoker;Addison;CA;5 .99;145 Fiction;Curse of the Wolfman;Hageman;Wesley;MA;10.59;876 NonFiction;How to Pass Java;Willis;Wiley;NY;1.99;technolog y Fiction;The Mummy;Rice;Addision;CA;7.99;954 NonFiction;History of Texas;Smith;Prescott;CA;9.75;histor y 2. Write class Publisher with attributes name and state. 3. Rewrite the Book class to include a type Publisher attribute. 4. Write two children of the Book class: FictionBook and NonFictionBook. FictionBook has an additional attribute, fictionCode. NonFictionBook has an additional attribute, catagoryCode. 5. Rewrite the BookTest program. Method buildInstances will read the data from the file, create instances of FictionBook and NonfictionBook from the data, assign these instances to the Book array and return the bookArray as before. Since it is reading data from the file, it does not have any method parameters. 6. Method createCharges should work the same.
