please can some one help me. i can'nt get the problem below to work.
The bookuser class calls the book class and uses it to print out a
book title.



import java.util.*;
public class Book{




public String title, isbn, publisher;
public Date pubDate;


public Book(String t, String i, String p, Date d)
{
title = t;
isbn = i;
publisher = p;
pubDate = d;
}

}


import java.util.*;
public class Bookuser{

public static void main( String[]args)

{

Date Today;

Book b1 = new Book("great
expectasions","01234","orchard",Today);
System.out.println( b1.title);



}


}
