> In the current version [CSVFormat#withHeader|https://commons.apache.org/proper/commons-csv/apidocs/org/apache/commons/csv/CSVFormat.html#withHeader(java.lang.String...)] is only used by CSVParser. It would be nice if CSVPrinter also supported it. Ideally, the following line of code
> {code:java}
> CSVPrinter csvPrinter
>   = CSVFormat.TDF
>     .withHeader("x")
>     .print(Files.newBufferedWriter(Paths.get("data.csv")));
> csvPrinter.printRecord(42);
> csvPrinter.close();
> {code}
> should produce
> {code}
> x
> 42
> {code}
> If you're alright with the idea of automatically inserting headers, I can attach a patch.
