How can you add a snippet of code in your JavaDoc? - Cracking the Java Coding Interview

There are multiple ways to add code snippets in JavaDoc comments. The simplest approach is embedding code directly in the JavaDoc comment, but it cannot be validated at runtime. A better approach uses an external class with a region tag referenced via the @snippet tag, stored in a snippet-files directory — this allows IDEs to render JavaDoc on the fly, though Maven may struggle running these as unit tests. Alternatively, the --snippet-path option can be passed to the JavaDoc tool. All these approaches also work when writing JavaDoc in Markdown.
