Debugging and logging are the fresher survival skills. This module is an elevation arc: it opens with logging (the overview, the levels, SLF4J and Logback — the stack you'll use), then reading stack traces and common exceptions (the diagnosis skills). Debugging techniques and the IDE debugger follow at the applied tier, then code review basics — where a fresher learns to catch bugs before they ship.
