SQL Syntax Error for MySQL but not sure where...

Can someone spot my error? I cannot seem to figure it out. Could be my jdbc driver, I'm currently using 5.1.14 jdbc driver.

public int update(String sku, String category, String description, String name, String price, String inventoryLevel, String brand, String gender, String size ) {
        int i;
        con = dbcon.SimpleConnection();

PreparedStatement ps = null;
        ResultSet rs;
        int prodId;

try {
            System.out.println("Indise of ProductDB update() and sku variable =" + sku);

//String queryID = "Select ProductId FROM Product WHERE sku = ?;";
            String queryID = "SELECT ProductId FROM Product WHERE sku = '" + sku + "';";
            //ps.setString(1, sku);

//ps = con.prepareStatement(queryID);

stmt = con.createStatement();
            rs = stmt.executeQuery(queryID);
            
            
            //rs = ps.executeQuery();

rs.next();
            System.out.println("Result Set inside of ProductDB update() =" + rs.toString());

prodId = Integer.parseInt(rs.getString("ProductId"));
            System.out.println("Product ID =" + prodId);

} catch (SQLException sqex) {
            sqex.printStackTrace();
            return i=-1;

}

//This method updates the record with a matching Product ID.
        //It returns a valurs = stmt.executeQuery(queryID)e of 0 if the email address can't be found.
        String query = "UPDATE Product SET "
                + "sku = ?, "
                + "Category = ?, "
                + "Description = ?, "
                + "Name = ?, "
                + "Price = ?, "
                + "InventoryLevel = ?, "
                + "Brand = ?, "
                + "Gender = ?, "
                + "Size = ?, "
                + "WHERE ProductId = ?";
        try {

ps = con.prepareStatement(query);
            
            ps.setString(1, sku);
            ps.setString(2, category);
            ps.setString(3, description);
            ps.setString(4, name);
            ps.setString(5, price);
            ps.setString(6, inventoryLevel);
            ps.setString(7, brand);
            ps.setString(8, gender);
            ps.setString(9, size);
            ps.setInt(10, prodId);
            
            i = ps.executeUpdate();
            System.out.println(query);

return i;
        } catch (SQLException e) {
            System.out.println(e);
            return -1;
        } finally {
            close.closeAll();
        }
    }

This is the actual stacktrace:

My guess: the comma at line 52 (in your posted code).

That was it! Must have been a copy & paste error for the last update variable.

Thank you for your help. R
