JTable (Deleting row)

[vikas dhimole]

I have created a table, and I want to delete a row using a button.
I am using TableModelListener to identify the row which user editing and listselection listener for selected row.

when i am deleting a row using a button some exception is coming.That exception is ArrayIndexOutOfBoundsException.


i am not using any model for my table.

What I think problem is because I m using a TableModelListener which will fired whenever i want to delete a row.

please give me suggest to solve this problem,
thanks in advance
