know:
$Matches the ending position of the string or the position just before a string-ending newline. https://en.wikipedia.org/wiki/Regular_expression
ask:
How can I make $ to match ONLY "ending position of the string", NOT "or the position just before a string-ending newline"?
eg:
If you run
String str = "the first sentence\n"
"the second sentence\n"
"the third sentence\n";
System.out.println(str.replaceAll("$", "--"));
current behavior
Output will be
the first sentence
the second sentence
the third sentence--
--
desire behavior
Output desire to be
the first sentence
the second sentence
the third sentence
--
CodePudding user response：
You can use the "absolute end of string" construct \z
System.out.println(str.replaceAll("\\z", "--"));
