Virtual Library Project

[asmohamed12]

So basically, this is my project:

* Write a LibraryManager class that provides a GUI application to add, check out, look up the status of, and return books in a library.

The GUI compiles and executes perfectly. I just need to finish the code for the LibraryBook in order to make the GUI function correctly.
-------------------------------------
So here is what I've gotten so far. I'm having trouble trying to write the code to actually add the books to a Library(ArrayLi st). Do I need to create an arrayList first, if so, how do I do so? I have my GUI setup, I just need to figure out the code to go into the MouseClicked part as well as the rest of the code. I've gotten a good portion of the code written, I'm just not exactly sure how to put it all together. I'm obviously a novice, but this doesn't seem too difficult. Any help would be gladly appreciated. Thanks.

I'm confused: is LibraryBook an interface or a class?

[BigDaddyLH]

Please enclose your posted code in [code] tags (See How to Ask a Question).

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.

Please use [code] tags in future.

LibraryBook is actually a class, I can't find the edit button to change that as well as adding the (code) (/code) tags, I'll be sure to use them for future reference

[Laharl]

You should change LibraryBook to a class rather than an interface. As it is, you can't declare any objects of the interface because that's what an interface is. Thus, your code won't work since you can't have any LibraryBooks to work with unless you have some subclasses written that are actually classes.

[BigDaddyLH]

If LibraryBook is a classs, then you can't do this:

[CODE=Java]public class LibraryManager extends JFrame implements LibraryBook[/CODE]

Even if it were an interface, it doesn't make sense to say "A Library manager is a library book". Perhaps "A Library manager knows library books".

Does that make sense to you?

[asmohamed12]

So I'll just make LibraryBook a class and put it inside of LibraryManger.

I still am having trouble actually creating books and having the functions implemented to do the actions necessary. I believe I need to use some sort of ArrayList, but not sure how to do so, any suggestions?

Lists and other collections are easy to use. I suggest you take the Sun tutorial on the collection framework: http://java.sun.com/docs/books/tutor...ons/index.html
