  • Your question headline and description doesn't match. Do you want to split by "\n" or get all the string which has three characters followed by 7 digits? – Rohit5k2 Mar 07 '19 at 07:39
  • not need to get only "PRX1686559" patterns it output – Mohanraj Archunan Mar 07 '19 at 07:48
  • @Rohit5k2 /n not matters – Mohanraj Archunan Mar 07 '19 at 07:49
  • A regular expression like `[A-Z]{3}\\d{7}`? Matcher, find, group. It’s described in a lot of places, so just search for the details. You may want to require a word boundary before and after, search for that too. – Ole V.V. Mar 07 '19 at 07:54
  • your title says `Want to print string contains 3 letters followed by 7 digits`? And you're asking how to split a string? you may read this guideline - https://stackoverflow.com/help/how-to-ask – Van_Cleff Mar 07 '19 at 07:54

Try this

String example = "ATS0657882\nPRX1686559\n name: something,hello";
Pattern p = Pattern.compile("[A-Z]{3}[0-9]{7}"); // or [A-Z]{3}\\d{7}
Matcher m = p.matcher(example);

while (m.find()) {
    Log.i("Findings", "values are " + m.group());
}
