JTable Java Error Stack OverFlow when setvalue to a specific column

Question

This is my Code below. I have created a Jtable with 4 column and 3 rows. and add table model listener, In the Table change Listener, When i set the value in a particular column

Answer 1

JTable#setValueAt will call TableModel#setValueAt, which will trigger a TableChanged event, which is why it's causing you a StackOverflowException (it's caught in an infinite loop)

The better solution would be to override the TableModel#setValueAt and if the column 0, 1 or 2 is updated, also calculate the value for column 3, but don't forget to fire a cellUpdated event
