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

Answer 1

If, as I interpret, you're looking for the first alphabetic character in a sentence or its index through regular expressions, here's an example:

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

Output

Found: T
At: 6
