I’m trying to match a string, starting with a dot using java’s matches method. Why this doesn’t work:
".why?".matches("\\.*");
When I use a single slash, i’m getting an error for invalid escape sequence.
Thanks in advance
"\\.*"matches a string consisting of zero or more'.'s. It matches the following (quoted) strings:(and so on)
You want:
"\\..*"instead. Note that.by default does not match line breaks, so it wouldn’t match the following string:For such string to be matched, you need to enable DOT-ALL:
"(?s)\\..*"
