Refresh the JTable on updating the data

Question

Below is my code:-

public class MainScreen extends javax.swing.JFrame {

    private TableRowSorter<TableModel> sorter;

    public MainScreen() {
        initComponents();
        this.setSize(java.awt.Toolkit.getDefaultToolkit().getScreenSize());

        sorter = new TableRowSorter<>(tblCustomer.getModel());
        tblCustomer.setRowSorter(sorter);
        List<BasicDetailsDTO> findAll = UtilDAO.getDaoBasicDetails().findAll();
        System.out.println("I'm here  "+findAll.size());


        ((DefaultTableModel) tblCustomer.getModel()).setDataVector(getDataVector(findAll), getVectorHeader());
        tblCustomer.setAutoCreateRowSorter(true);
        tblCustomer.getColumnModel().getColumn(0).setMinWidth(0);
        tblCustomer.getColumnModel().getColumn(0).setMaxWidth(0);

    }

    public static Vector getDataVector(List<BasicDetailsDTO> listData) {
        Vector dataVector = new Vector();
        for (BasicDetailsDTO instance : listData) {
            Vector row = new Vector();
            row.add(instance.getId());
            row.add(instance.getParticulars());
            row.add(instance.getBookedBy());
            row.add(instance.getContactPerson());
            row.add(instance.getMobileNo());
            row.add(instance.getEmail_id());
            dataVector.add(row);

        }
        return dataVector;

    }

    public static Vector getVectorHeader() {

        Vector header = new Vector();
        header.add("ID");
        header.add("Particulars");
        header.add("BOOKED BY");
        header.add("CONTACT PERSON");
        header.add("MOBILE NO");
        header.add("EMAIL ID");
        return header;

    }

Whenever I update the data within the table, the updated data is not reflected. The updated data is reflected only when I reopen the window. Kindly help me through. Thanks in advance.

Answer 1

1. why voids for DefaultTableModel and JTableHeader are static

2. remove rows from DefaultTableModel

3. use DocumentListener instead of KeyListener for RowFilter

4. why is there initialized two different LookAndFeels

5. updates to DefaultTableModel must be done on EDT, more in Oracle tutorial Concurrency in Swing - The Event Dispatch Thread

6. search for ResultSetTableModel, TableFromDatabase, BeanTableModel

7. rest of issue is hidden in shadowing void or classes, note remove all static declare, there should be static only main class
