> It does, but it also matches spaces (which it currently doesn't). On the
other hand, it's one regex vs. three, so that could be a benefit. What do you
think, @Tibor17?
It also replaces multiple consecutive whitespaces with a single whitespace:
List<String> whitespaces = List.of(
"\n",
"\r",
"\n\r",
"\t",
" ", // single whitespace
" ", // double whitespaces
" ", // triple whitespace
" ", // 	
"\n\n\r\t ",
" \n \n\r \t ");
List<String> stripWhitespaces = whitespaces.stream()
.map(str -> str.replaceAll("\\s+", "' '")).toList();
System.out.println(stripWhitespaces);
Output:
[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']
