Most simple code to populate JTable from ResultSet

Question

I googled the whole day and no luck. I call getnPrintAllData() method after pressing OK button. So the code is:

public class DatabaseSQLiteConne

I think this is the Easiest way to populate a table with ResultSet with a method like

FillTable(MyTable, "select * Customers;");

And a very simple method can be made as

public void FillTable(JTable table, String Query)
{
    try
    {
        CreateConnection();
        Statement stat = conn.createStatement();
        ResultSet rs = stat.executeQuery(Query);

        //To remove previously added rows
        while(table.getRowCount() > 0) 
        {
            ((DefaultTableModel) table.getModel()).removeRow(0);
        }
        int columns = rs.getMetaData().getColumnCount();
        while(rs.next())
        {  
            Object[] row = new Object[columns];
            for (int i = 1; i <= columns; i++)
            {  
                row[i - 1] = rs.getObject(i);
            }
            ((DefaultTableModel) table.getModel()).insertRow(rs.getRow()-1,row);
        }

        rs.close();
        stat.close();
        conn.close();
    }
    catch(InstantiationException | IllegalAccessException | SQLException e)
    {
    }
}
