Question

How to check in Java with regular expression if some string matches with

Monday ptnumber Operating Mode

where number ( after pt ) has concrete value like 0,1,…99,.. – any integer?
Mondaypt and Operating mode are hardcoded just number can change in string.

Answer 1

This will also extract the number.

String input ="Monday pt23 Operating Mode";
Pattern p = Pattern.compile("Monday pt([0-9]+) Operating Mode");
Matcher m = p.matcher(input);
boolean found = m.find();
if (found) {
    String number = m.group(1);
    System.out.println(number);
}
