My first major project (at an internship) had all the comments on every file (even getters / setters, and it even had getters/setters because someone told me to). Interestingly enough it was a project that had to read static analysis tools' output and combine it into a single report / webapp, so I was very aware of all the output that was reported and all the niggly little things that these tools (think PMD, CPD, FindBugs, etc) pointed out. Including how a getter wasn't commented.
