Question

Here is what I got so far

also can anyone help me align the output

Book-Video-Music Lab Add the classes in red to your Library Lab code: Person Publication count:static int # pubNumber:int # title:string # borrower-null: Person + Publication title:string) + get + setBorrower(p:Person):void +display():void name: string Person(name:string getName():string +setName(n:string)void Borrower():Person Book Video Music pages:int ormat:Format genre string title:string, pages:int) Video(title:string, format:Format) Music(title:string, genre:string + display):void + display():void display):void Note these changes Publication member variables are now protected (# in diagram) rather than private (-) Video Format is an enumerated data type with values FLV, MOV, MP4, and wMv The display methods in Book, Video, and Music override Publication display The constructors for Book, Video, and Music pass title on to the Publication constructor Revise your Library Lab main program. Create three separate arrays of objects, one each for Book, Video, and Music, and add example objects using hard-coded data. Then, display your example objects as follows Books Pub Number Title Borrower Name es War and Peace Object-Oriented Programming Grapes of Wrath Lady Gaga Albert Einstein Muhammed Ali 1500 998 246 Videos Pub NumberTitle Borrower Name Format Star Wars Donald Trump mp4 Music Pub Number Title Borrower Name Genre Don't Worry Be Happy Kind of Blue Indira Ghandi Diego Maradona 4 Popular
