You only seem to have one boolean for "borrowed" whereas you need one boolean per book. You could use another ArrayList, like for the names etc.
ps: In Java the "right" way to do this is to define a class called "Book" that has instance variables for name, borrowed etcetc, then just one ArrayList of Book objects.
You'll find that updating your books (especially to delete a book) is very tedious with your current data structure.

i defined a Book class like you said, but how am i going to add elements in my ArrayList? could you give me an example?

and wouldnt be the type of my ArrayList be Book and not String?

Yes, it's array list of Books.
Your Book class is a good start - but don't forget the instance variables for author, publisher etc
You just need to create new Books with their titles, autor, publisher etc etc and add those books to the arraylist. You add Books to an ArrayList<Book> exactly the same way that you added Strings to an ArrayList<String>

how do i add auhtor, publisher, and id? beacause it only shows the title. the getAuthor() returns null...

Easiest way is probably to create the Book completely (using your set... methods, or by passing all those values to the constructor)before adding it to the ArrayList
Book b = new Book...
b.setAuthor(...
b.setPublisher(...
...
books.add(b)

OR

books.add(newBook(title, author, publisher....

ps You should chjange the name of your ArryList to match how you use it - it's not just a list of book name any more
