$1.$ Start by creating the $`$Book$`$ class.

$-$ Define the attributes: $`$title$`,`$author$`,$ and $`$ISBN$`.$

$-$ Create methods to get book details, borrow a book, and return a book.

$2.$ Next, design the $`$Library$`$ class.

$-$ Define the attributes: $`$listOfBooks$`($use an Array$)$ and $`$borrowedBooks$`($also an

Array$).$

$-$ Implement methods to add books to the library, borrow books using ISBN, return

books, and list available books.

$3.$ In the $`$main$`$ method $($you can create a separate $`$Main$`$ class or use any of the two

classes$),$ demonstrate the functionality by creating books, adding them to the library,

borrowing, and returning them.
