## TL;DR
Write the missing doc comments, or relax doclint for the build. Doclint promotes missing comments on public elements from warnings to errors.

## Error
```text
error: no comment
```

## Steps
1. Find the element: the error is reported with file and line; it is a public class, method, or field without any doc comment. Expected: the uncommented element identified.
2. Write a proper doc comment (`/** ... */`) describing the element, including @param and @return where applicable. Expected: every public element has a comment.
3. If the codebase is mid-migration and full coverage is not feasible yet, run javadoc with `-Xdoclint:none` temporarily, or `-quiet` to reduce noise, while you add comments incrementally. Expected: a deliberate, temporary relaxation, not a permanent one.
4. Re-run `javadoc` with doclint enabled. Expected: no "no comment" errors.

## When to use
- Javadoc fails with "error: no comment" under doclint
- CI recently enabled doclint on a legacy codebase
- A docs agent generated code without doc comments

## When not to use
- Doclint is off and these are plain warnings (lower priority)
- The element should not be public (reduce visibility instead)
- The error is about malformed HTML in an existing comment (different fix)

## Tool compatibility
JDK 8 through 21. Doclint behavior is consistent across these versions.

### Variant phrasings
### no comment errors only for package-private members
Doclint checks accessibility levels per its settings; missing comments on public API are the errors that matter most.

### want doclint but not the missing-comment check
Use `-Xdoclint:all,-missing` to keep HTML and syntax checks while allowing missing comments during migration.

## Why it happens
Doclint was introduced to hold generated API docs to a quality bar, and "no comment" is its strictest check. Enabling it on a codebase that never wrote doc comments turns years of missing comments into build errors at once.
