I Had an Error in Clear the JTable Content using JButton . Here is my Code .

private void ClearCartBTActionPerformed(java.awt.event.ActionEvent evt) {

   try{
       DefaultTableModel model = (DefaultTableModel)Cart_table.getModel();  //Cart_table (Var Name of Jtable)

       while(model.getRowCount()>0){
           for(int i= 0 ; i <model.getRowCount();i++){
               model.removeRow(i);
           }
       }

   }catch(Exception e){
       JOptionPane.showMessageDialog(null, e);
   }

}

Only I had an Error in model.removeRow(i);

What should I do ?

What kind of error and what is the message? – Jens Sep 05 '15 at 07:42
it has a redline or errorline for model.removeRow(i); which says cannot find symbol , symbol :method removeRow(int) – Greg G II Sep 05 '15 at 07:45
what is stacktrace ? Hahaha . sorry because I'm a beginner in netbeans – Greg G II Sep 05 '15 at 07:53
It is a compile error, so you have no stacktrace. – Jens Sep 05 '15 at 07:53

Can you show the import statement of `DefaultTableModel`? – Jens Sep 05 '15 at 07:54
So , What should I do ? – Greg G II Sep 05 '15 at 07:55
import groovy.model.DefaultTableModel; here sir ? – Greg G II Sep 05 '15 at 07:57
Remove the rows in reverse order – MadProgrammer Sep 05 '15 at 07:58
It should be `import javax.swing.table.DefaultTableModel` – Titus Sep 05 '15 at 07:58
If you're using javax.swing.table.DefaultTableModel, you can use setRowCount and pass it 0 – MadProgrammer Sep 05 '15 at 08:02
Thanks a lot to all you , the error has gone . but I it doesn't clear the Table content :( . Can you help me ? Can you Give me another process to Clear the Content in the JTable using JButton . – Greg G II Sep 05 '15 at 08:05
You have to refresh the table, you can use `model.fireTableDataChanged()` to do that. – Titus Sep 05 '15 at 08:09
I doesn't clear or update in Database in MS Access :( – Greg G II Sep 05 '15 at 08:41
