here is my class file:
import java.util.Scanner;
public class Book{
          private BookDetails[] details;
          public Book(){
          BookDetails[] details = new BookDetails[15];
          details[0] = new BookDetails("The Secret", "Rhonda Byrne", "0001", 10);
          details[1] = new BookDetails("Secrets of Self-Made Millionaires", "Adam Khoo", "0002", 10);
          details[2] = new BookDetails("An Illustrated Biography of the World's Most Successful Investor", "Warren Buffet", "0003", 15);
          details[3] = new BookDetails("How good do we have to be?", "Harold Kushner", "0004", 8);

          do{
               Scanner input = new Scanner( System.in );
               System.out.print( "Enter the title of the book.");
               bookTitle = input.nextLine();
               public BookDetails findBook( String bookTitle ){
               int Book = details.length;
               for( int i = 0; i < Book; i++ ){
                    if( details.getBookTitle().equalsIgnoreCase( bookTitle ))
                    return details[i];
               System.out.println( "Book title : " + bookTitle + " found" + "\n"
                         + "Details for book title " + bookTitle + "\n"
                         + "Author : " + BookDetails.getAuthor() + "\n"
                         + "CatalogueNo : " + BookDetails.getCatalogueNo() + "\n"
                         + "Cost : $" + BookDetails.getCost());
               System.out.println( "Proceed to rent? <Y/N> : ");
               select = input.nextLine();
               if ( select.equalsIgnoreCase( "Y" ))
               System.out.print("Enter the name of customer : ");
               na = input.nextLine();
               System.out.print("Enter the address of customer : ");
               add = input.nextLine();
               System.out.print("Enter the phone number of customer : ");
               phone = input.nextLine();
               CustomerDetails person = new CustomerDetails( na, add );
               System.out.println( "Printing out receipt for " + person.getName() + ".....");
               System.out.println( "At address : " + person.getAddress() );
               System.out.println( "Renting book title " + bookTitle + " for $" + BookDetails.getCost());
               System.out.println( "Serving next customer....." );
               if ( select.equalsIgnoreCase( "N" ))
               System.out.println( "Serving next customer....." );
               }//for
               System.out.println( "Book title: " + bookTitle + " not found" );
               System.out.println( bookTitle + " not available" + "\n"
                              + "Serving next customer....." );
               return null;
               }//class
          }while( "E" );

Answer 1

ok. Now is like this:
import java.util.Scanner;
public class Book{
          String bookTitle, na, add, phone, select;
          BookDetails bookDetails = new BookDetails();
          do{
               Scanner input = new Scanner( System.in );
          do{
               System.out.print( "Enter the title of the book.");
               bookTitle = input.nextLine();
               BookDetails = BookDetails.findBook(book Title);
          }while(Book == null);
               System.out.println( "Book title : " + bookTitle + " found" + "\n"
                         + "Details for book title " + bookTitle + "\n"
                         + "Author : " + BookDetails.getAuthor() + "\n"
                         + "CatalogueNo : " + BookDetails.getCatalogueNo() + "\n"
                         + "Cost : $" + BookDetails.getCost());
               System.out.println( "Proceed to rent? <Y/N> : ");
               select = input.nextLine();
               if ( select.equalsIgnoreCase( "Y" ))
               System.out.print("Enter the name of customer : ");
               na = input.nextLine();
               System.out.print("Enter the address of customer : ");
               add = input.nextLine();
               System.out.print("Enter the phone number of customer : ");
               phone = input.nextLine();
               CustomerDetails person = new CustomerDetails( na, add );
               System.out.println( "Printing out receipt for " + person.getName() + ".....");
               System.out.println( "At address : " + person.getAddress() );
               System.out.println( "Renting book title " + bookTitle + " for $" + BookDetails.getCost());
               System.out.println( "Serving next customer....." );
               if ( select.equalsIgnoreCase( "N" ))
               System.out.println( "Serving next customer....." );
               }//class
          }while( "E" );
But, there's still error saying illegal start of type at "do{"
