Java scan using offset

Question

How can I scan a set of characters on a card which includes a particular word, but after scanning it omits this particular and returns the other characters.
For example, on the card or image there is
IJN 173648493637 but I want to scan only the numbers in these characters. The code selects characters that have IJN because there are a whole lot of strings and characters. NB: the numbers will differ in other images.

Answer 1

Just an idea, save the scanned input as an array, then only use chars from index 2 on?

Answer 2

if there is space between and number is String in result

import java.util.Scanner;
...
String str = "IJN 173648493637";
Scanner sc = new Scanner(str);
sc.next();
String numstr = sc.next();
System.out.println( numstr ); // 173648493637
