My assignment asked the following. I am unable to get the UI working and having trouble with the rest of the bullet points below. Answer in code only is fine, once I see it, it usually makes a lot more sense. Any help would be appreciated!!

Create a user interface for the Library application that allows the user (i.e., the Librarian) to enter Book objects.

Create a business layer manager, BookMgr, with the following stubbed-out method: public Book storeBook(Book book). The add button will cause the user-supplied information to be packaged into a domain Book object. It will also:

Pass the domain Book object to the BookMgr.storeBook function.

Display the state of the Book using its overridden toString() method; e.g System.out.println(book.toString());

CODE

package libraryapp;

public class Book { private String[] author; private int ISBN; private String title;

// Constructor public Book(String authors[], int ISBN, String title) { this.author = new String[authors.length]; for (int i = 0; i < author.length; i++) { author[i] = authors[i]; } this.ISBN = ISBN; this.title = title; }

public Book() { throw new UnsupportedOperationException("Not supported yet."); }

public String[] getAuthor() { return this.author; }

public int getIsbn() { return this.ISBN; }

public String getTitle() { return this.title; }

public void setAuthor(String[] author) { this.author = author; }

public void setISBN(int ISBN) { this.ISBN = ISBN; }

public void setTitle(String title) { this.title = title; }

public boolean validate() { if (author == null || author.equals("")) return false; if (title == null || title.equals("")) return false; if (ISBN == 0) return false; return true; } }
