It doesn't sound like you're looking for "obfuscated" code, which is what the links below show. But rather real code that's more complicated than slide examples

It doesn't sound like you're looking for "obfuscated" code, which is what the links below show. But rather real code that's more complicated than slide examples. I would look for random code people wrote, for example on github: https://github.com/search?utf8=%E2%9C%93&q=sort&repo=&langOverride=&start_value=1&type=Code&language=Java https://github.com/search?utf8=%E2%9C%93&q=sort&repo... And then just look at the code and try to understand how it works. This result for example seems to implement basic functions and is well commented: https://github.com/erlide/erlide/blob/6b836bcb0770d23c4471f490bea50b9141d1909e/org.erlide.core/src/org/erlide/core/common/Util.java https://github.com/erlide/erlide/blob/6b836bcb0770d23c4471f4... Hope this helps
