Problem Statement : Retrive data from database and display on JTable in java.

CODE: (for retrieve) *change code according to your need

String tquery = "SELECT * FROM Member";
        DbConnection obj = new DbConnection();
        ResultSet r = obj.Retrive(tquery);
        while (r.next()) {
            int i = r.getInt(1);
            String d = r.getString(2);
            String e = r.getString(3);
            String f = r.getString(4);
            String h = r.getString(5);
            String w = r.getString(6);
            DefaultTableModel model = (DefaultTableModel) (Member_table.getModel());
            model.addRow(new Object[]{i, d, e, f, h, w});
        }

CODE (simplified):

        String tquery = "SELECT * FROM Member";
        ResultSet rs = st.executeQuery(sql);
        while (r.next()) {
            int i = r.getInt(1);
            String d = r.getString(2);
            DefaultTableModel model = (DefaultTableModel) (Member_table.getModel());
            model.addRow(new Object[]{i, d);//add row to JTable
        }

if thisDefaultTableModel model = new DefaultTableModel(); not work use DefaultTableModel model = (DefaultTableModel) (Member_table.getModel());

Hope it helps you!
