I am working on UrlyBird(1.2.3) and I have a question about data file schema. I read few posts saying that it is ok to hard code the header information.
I was able to read the header information from my file using the RandomAccess file object.
I am not sure how can I make schema reading dyanmic so when i create JTable later, I can read them dynamically. Is there a way?

Hi Paul, welcome to JavaRanch.

To use JTable dynamically, you have to implements MVC pattern. It is covered on book titled "SCJD Exam with J2SE" by Apress.

You have to extend AbstractTableModel and implement all the abstract methods specifics to your needs.


Hope that will help you

thanks for your reply.

one more question, the schema section of the exam, I am using hardcoded static final fields for size ( private static final int location = 64 .

Is there a way to make that dynamic..?
 
It is sorta covered in the JavaRanch Style Guide.
