Yahoo Finance Quote Download Java Update

Overview

Back in June of 2017 I posted an article describing how to retrieve quotes from the Yahoo Finance page.

The other day I received a message from a user who found that the program no longer worked. After looking into the issue I found that Yahoo responds differently depending on the User-Agent setting being presented to the server. The quick fix was to change the value submitted.

Original

New
