HTML table is relatively simple. You can load the page, parse the HTML (various HTML parsing libraries are available), extract the table and convert it to CSV (which Excel can load), or directly create an Excel file, for example. using Java POI as suggested above.
The flash part is much more complicated. There are many tools to capture flash memory for an image; you will need to use one of them. This can be tricky because Flash can be interactive, so you may need to remotely control part of Flash so that it displays the correct image before capturing. It is hard to say without additional information.
