How can I retrieve all row information from a database table.

Question

I have a jsp file which calls info from columns in a table. My question, is how can I edit it so that it retrieves all the rows?
I tried using resultset SalesInfo.next() which only retrieves the last row value and resultset SalesInfo.first() which only retrieves the first row value.
Here is my code
public ResultSet SalesInfo;
public void getSalesInfo()
          try
               Statement stmt = db.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
               SalesInfo = stmt.executeQuery("SELECT sales_id,cust_id,product_id, quantity from sales;");
               SalesInfo.first();
               setCartsales_id (SalesInfo.getString("sales_id"));
               setCartcust_id (SalesInfo.getString("cust_id"));
               setCartProduct_id(SalesInfo.getString("product_id"));
               setCartquantity (SalesInfo.getString("quantity"));
          catch(SQLException e )
               setCartsales_id(e.toString());
               e.printStackTrace();
Also I apologise for not having the proper code format as I had a problem with my keyboard.

     public class SalesDB{
    public static synchronized Vector getSalesDetail(Connection connection) throws SQLException{
        String query = "SELECT * from Sales;"
       Statement statement = connection.createStatement();
        ResultSet results = statement.executeQuery(query);
        Vector sale_details = new Vector();
        while(results.next() == true){
     SaleInfo saleInfo = new    SaleInfo(results.getString("sales_id"),results.getDouble("cust_id"),results.getString("product_id"));
            sale_details.add(saleInfo);
        results.close();
        statement.close();
        return sale_details;
}
