Refresh JTable using Vectors strings

Question

I'm trying to refresh my table but it won't refresh. I tried using the fireTableDataChanged() as well as creating a new model but my Table will not budge. I can get the initial values in but I can't figure out how to refresh it. HS = new Vector(Arrays.asList(finalHSArr)); SF = new Vector(Arrays.asList(finalFlagsArr)); I have two separate JTables that I am trying to refresh and these are the new values above. I've been trying for 6 hours now.

public class TemplateGui extends JFrame  {
        private final ButtonGroup buttonGroup = new ButtonGroup();
        private JTextField textField;
        private static String [] sortedRoles_Flags,finalFlagsArr,finalHSArr;
        private static String finalFlags="",finalHS="",columnToConvert="Result";
        private Vector<String> SF,HS,column;

When you do

HS = new Vector<String>(Arrays.asList(finalHSArr));
SF = new Vector<String>(Arrays.asList(finalFlagsArr));

You change what HS and SF where point at, however, it does not change what, internally, the TableModel is pointing at.

You could use DefaultTableModel#setDataVector, but i might simpler to simply create new TableModels and set them to the JTables instead.

hsTableModel = new DefaultTableModel(HS, column);
hotelSecurityTable.setModel(hsTableModel);

sfTableModel = new DefaultTableModel(HS, column);
securityFlagsTable.setModel(sfTableModel);

As it's pretty much the same thing...

Updated

DefaultTableModel is expecting a Vector of Vectors, but you're supplying a Vector of Strings.

Try something like...

hsTableModel.setRowCount(0);
for (String row : HS) {
    hsTableModel.addRow(new Object[]{row});
}

Instead...
