I need to match and parse data in a file that looks like:
4801-1-21-652-1-282098
4801-1-21-652-2-282098
4801-1-21-652-3-282098
4801-1-21-652-4-282098
4801-1-21-652-5-282098
but the pattern I wrote below does not seem to work. Can someone help me understand why?
final String patternStr = "(\\d+)-(\\d+)-(\\d+)-(\\d+)-(\\d+)-(\\d+)";
final Pattern p = Pattern.compile(patternStr);
while ((this.currentLine = this.reader.readLine()) != null) {
final Matcher m = p.matcher(this.currentLine);
if (m.matches()) {
System.out.println("SUCCESS");
}
}
It looks correct. Something odd is conatined in your lines, probably. Look for some extra spaces and line breaks.
Try this:
final Matcher m = p.matcher(this.currentLine.trim());
Have you tried escaping the -
as \\-
?
