Help me in getting the value of a cell after editing in Jtable

Hi All,

Can any one please help me in getting the value of the cell after editing it

My main idea is to update the database after editing a cell in the Jtable,

I am able to edit it with a JTextField but When I am getting the edited value I am getting the error ,

Can you please help me in this,

I am placing my piece of code as follows




here I should get the value when I click on the Update button and should directly update this value to the data base

But I am getting the following error because my edited value is an int and i used JTextField for editing so it takes a String value

I don't see any reason to use a custom editor. Just use the default editor. Then when you want data from the table you use:



You may want to read Table Stop Editing to make sure the edited value has been saved to the model.

Hello Rob Camick,

Thank you very much for your documentation,

I had been blocked up here

My editing should end as soon as I click on the update button and should get the editing value,

can you please give some example code how to get this,


Thank you very much,
