You can just read the html file using java.nio, parse and modify it with Jsoup and save it to a file again using java.nio:

Path input = Path.of("input.html");
Document document = Jsoup.parse(Files.readString(input), "UTF-8");
document.select("#my-id").attr("class", "test");
Path output = Path.of("output.html");
Files.writeString(output, document.outerHtml());

For example if the input file looks like this:

<html>
 <head>
  <title>Foo</title>
 </head>
 <body>
  <div id="my-id">Bar</div>
 </body>
</html>

The output file will be modified like this:

<html>
 <head> 
  <title>Foo</title> 
 </head> 
 <body> 
  <div id="my-id" class="test">Bar</div>  
 </body>
</html>

But remember that the whitespaces of the output file could be different from the input file.
