有人可以告诉我另一种编写此代码行的方式吗？

Question

I know this is a strange question but for research purposes could anyone tell me a different way of writing this line of code? I am making a word cloud in The "forEach(s -> ignoreWords.add(s.toUpperCase()));" is the line of code I would like to change. Preferably not a lambda

Thanks very much in advance!!!!

Researched numerous pages

BufferedReader br = new BufferedReader(new InputStreamReader(input));
ignoreWords = new HashSet<String>(); 
 Stream<String> stream = Files.lines(Paths.get("/ignorewords.txt"));
stream.forEach(s -> ignoreWords.add(s.toUpperCase()));

Answer 1

Will this work?

Set<String> ignoreWords = Files.lines(Paths.get("/ignorewords.txt"))
                               .map(String::toUpperCase)
                               .collect(Collectors.toSet())
