Súper y subclases

1. this is my application class where i have instead array of objects

2. loanBook is a super class and loanDocumentry is a sub class that extends loanBook. This is declared at the top of the application class

   public static loanBook[] bookArray = new loanDocumetry[5];

then in my application class i have to add new documentry book so i use the scanner for inputs and then use them to add the new object

bookArray[i] = new loanDocumentry(
    title, author, publisher, year, noOfPages, genre);

and the book count in loanBook increases so I know each time I run the method it creates new book but when then printing the array out it looks like it never added any of those books to the array and that the only one i have added is the last one

            bookArray[i] = new loanDocuemntry(title, author, publisher, year, noOfPages, genre);
            i++;

}

loanBook Superclass & loanDocumentry Sub class both use set and gets
