How to Update the JTable Content

Question

Hi Friends
In my Program i have a Form having a JTable with shows some content on it. Now when the User Click on the Row it will ask where he wants to Edit that rows content. If the User gives Yes. then the Another JDialog opens with the Selected rows Data.
Now when the User makes changes in the Data and Clicks on the Edit Button. It Should Show the Entered Data on the JTable immediatly.
I am Posting my working Code. It works fine. But only the Updating the Newly entered Data to the JTable is not done.

}Could anyone Please Run my code and Help me to Update the JTable Record.
Thank you for your Help

Answer 1

Your EditForm needs acces to the TableModel and the current row you are editing. Then when the user clicks the save button you simply use the TableModel.setValueAt(...) method to update the model and the table will be repainted automatically.
