Pattern pat = Pattern.compile("Input(.*?)");
Matcher m = pat.matcher(s);

 if m.matches():

   print m.group(..)

Answer 1

Use a lookahead for Input and use find in a loop, instead of matches:

Pattern pattern = Pattern.compile("Input(.*?)(?=Input|$)");
Matcher matcher = pattern.matcher(s);
while (matcher.find()) {
   System.out.println(matcher.group(1));
}

But it's better to use split here:

String[] result = s.split("Input");
// You need to ignore the first element in result, because it is empty.
