FileOutputStream v. ByteArrayOutputStream: is there a noticeable difference in memory usage?
I'm using fastexcel to create the excel file, and I'm flushing it to the OutputStream after every row is written. Right now, I am using a FileOutputStream to write to disk. When the excel file is done being generated, I read it back in using InputStreamResource and stream the response. My thought process is that a ByteArrayOutputStream keeps everything in memory even if I'm flushing the excel file after every row, so I used the FileOutputStream. Does my logic track here? Or am I unnecessarily slowing things down with expensive filesystem IO?

how to create an excel file from a form in an android app
I would use some library like for example this one. So you collect all the data you want to store in a list or map, and iterate over it, then add them to the excel like shown in the documentation of the library (should always be the same way more or less for any library)

Favorite hidden gem library?
Jericho is seriously a crazy good library. I dont think most people even know about it. Definitely a hidden gem for sure. A while ago I tested multiple HTML parsers and Jericho came up ahead, by a massive margin, more than 3 times faster than jsoup for extracting stuff from html: https://github.com/newk5/html-parser-benchmark
