Reading Code
summary
Developers spend 58% of their time reading code, so a structured practice shows faster comprehension: a code reading club meets monthly (two years running) using printed snippets and timed exercises like a 1 minute first glance and a 5 minute summary, plus identifying five key lines and drawing dependency graphs. Practical tactics include building and running tests, using IntelliJ features (UML, module dependency matrix, debugger, bookmarks) and an IntelliJ AI Assistant to explain code, regex, SQL, or summarize commits.
