Do you discuss comments on colleagues' code with them and how does it usually happen?

Yes, discussing code comments with colleagues is an important practice for improving quality and sharing knowledge. This usually happens through code review: a colleague submits their code for review, and other team members leave comments with suggestions, questions, or remarks. It is important to do this constructively and respectfully, focusing on improving the code rather than on individuals. For example, you might suggest a more readable variable name or point out a potential error.

Example of a comment in a code review:

// It's better to use StringBuilder here for optimizing string concatenation
StringBuilder sb = new StringBuilder();
sb.append("Hello");
sb.append(" World");
return sb.toString();
