Indices may not be the most intuitive way to access record values. For this reason it is possible to
assign names to each column in the file:

Some CSV files define header names in their first record. If configured, Apache Commons CSV can parse
the header names from the first record:
<source>Reader in = new FileReader(&quot;path/to/file.csv&quot;);
Iterable&lt;CSVRecord&gt; records = CSVFormat.RFC4180.withHeader().withSkipHeaderRecord(true).parse(in);

To print a CSV file with headers, you specify the headers in the format:
</p>
<source>final Appendable out = ...;
final CSVPrinter printer = CSVFormat.DEFAULT.withHeader("H1", "H2").print(out)
final CSVPrinter printer = CSVFormat.DEFAULT.builder().setHeader("H1", "H2").build().print(out);

<p>
To print a CSV file with JDBC column labels, you specify the ResultSet in the format:
</p>
<source>final ResultSet resultSet = ...;
final CSVPrinter printer = CSVFormat.DEFAULT.withHeader(resultSet).print(out)
final CSVPrinter printer = CSVFormat.DEFAULT.builder().setHeader(resultSet).build().print(out);
