Does anyone have a good data recovery program?

Can anyone help me to write java program about data structure?

• Write a program to maintain a list of books you own. The book list is to be maintained as a linked list. Your program must accept the following commands. addBook (book) a book must have a title, an author , and a price to be added. Create a book entry with the corresponding values and add it to your book list. findBook (string) the string is a book title. If an entry is found in the list, print the entire entry. If not, print "not found". deleteBook(string) Delete the entry of the book list corresponding to a book title. For example deleteBook(“Programming”) should delete the entry with the title "Programming". For this form, the title must match exactly. If no such title exists, print a message indicating that there is no book with that title. expensiveBooks Print the title, author and price of all books with price greater than 100 printList Print the book list as it exists so far. Your list must be sorted (according to books title ) before being printed. listSize Finds the number of books in the list. You will need to define a class for a book entry in the book list containing the book title, book author and price. You may define the following methods: addBook (Book s) ; Book findBook (String st) ; // st is the book title void deleteBook (String st) ; // st is the book title void printList () ; int listSize(); //returns the number of books in the list Write a menu driven Java program that calls the above functions.

  I am familiar with VC and data structure when I was a graduate student, but have no idea of Java. So I can't help you.
