How to avoid empty value when using getValueAt() method?

When I add values to my JTable and perform save action the method, it gets performed. The issue is when I enter a single value say "TEST" in the JTable, getValueAt(1,0) returns empty . When I enter two values, say the table row count is 2, for i = 1 ,getValueAt(1,0) returns value "TEST" and for i = 2 ,getValueAt(2,0) returns value empty. I dont know why this is happening.

Code Snippet:

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

    DefaultTableModel tablemodel = (DefaultTableModel) jTable6.getModel();
    LinkedList<String> paramList = new LinkedList<String>();

    for (int i = 0; i < tablemodel.getRowCount(); i++) {

        System.out.println("Table row count :" + tablemodel.getRowCount());
        System.out.println("i " + i);
        String rowValue = (String) tablemodel.getValueAt(i, 0);
        paramList.add(rowValue);

        System.out.println("row value :" + rowValue);
        System.out.println(paramList.get(i));

    }
    SamIntegerResult intRes1 = svc.saveTSAServices(token, tsaservice, paramList, idList);

    if (intRes1.isSuccess()) {
        JOptionPane.showMessageDialog(this, new JLabel("Saved successfully", JLabel.CENTER), "Save TSA Service", JOptionPane.PLAIN_MESSAGE);
    } else {
        JOptionPane.showMessageDialog(this, "Error saving to database", "Error", JOptionPane.ERROR_MESSAGE);
    }

}

Do you guys have any idea? If so do post.

Try One of these when you enter the last value :

1) using the enter key

2) tabbing to the next cell

3) clicking on another cell with the mouse

and then try save. Hopefully, that will resolve the issue.
