Error while retrieving data from database to JTable which has JCheckbox in JTable using TableModelListener
Question
My JTable has a column having JCheckBox for maintaining status. When I don't implement TableModelListener and run the program, the data gets displayed in JTable. But when I run the code with TableModelListener implemented I get error. java.lang.ArrayIndexOutOfBoundsException: -1

int row = e.getFirstRow();
int column = e.getColumn();
I would guess one of the above variables contains -1.
Read your stack trace. It will tell you the line causing the problem.
A value of -1 means a row/column is not selected.
Then you need to modify the code in the listener to exit if either of the above values is -1.
