a program about class

how i solve this
Implement a class library that will hold information cards and loans ( whom you borrowed a book ) .
Loans may be made by registered persons , unless they are books available .
Each card has id , title and author , you can add or delete cards.
The application will have the menu - text interface - which look similar to the one below :
Choose the operation :
Displays the list books
Add book
Remove card
Search by author
Search by title
Register a loan
Returns a book
Shows loans
Use distinct classes , book , date , loans, people.
