How to get position of the first letter in a string [closed]

Answer 1

If I read the Java docs correctly, you're looking for the start method of the match object:

String line = "000 1 This is my message";
Pattern p = Pattern.compile("\\p{L}");
Matcher m = p.matcher(line);
if (m.find()) {
    System.out.println(m.start());
}
