What is the name of this class?

Question

I have a JTable which is instantiated like this:
"class table2 extends JTable {
     private int rows = 100, cols = 8;
     private Object[] rowData = new Object[cols];
When I try to refer to it as "table2," I get a null pointer exception.
My questions:
What is the name of that class?
Is there a way to reference it as "table2"?
Many thanks in advance.

Hello
I might have the answer to your problem but firstly, is that all the code there is? For example, where is the constructor for your class?
In answer to your questions:
1. You cannot reference an object until it has been created (this might explain the NullPointerException)
2. To reference it as "table2" you would do something like this:
table2 table2 = new table2();Looks a bit confusing... :(
You should start class names with capital letters and also choose a general name for the class like this:
MyTable table2 = new MyTable();
MyTable table3 = new MyTable();and so on.
Post another message if you need more help.
