Three Java experts share GitHub Copilot practices

On 21 October 2026, the GitHub Blog published a report on how three Java Champions with more than a decade of Java experience use GitHub Copilot in production and open-source projects. Vlad Mihalcea said Copilot cut feature development that would have taken weeks down to two days, and that he trained a custom skill on 65 articles so the generated text matched his personal style. The report so far covers only the above and does not include specific cases from the other two experts.
