Try this

try {
    Scanner io = new Scanner(System.in);
    String input = io.next();
    // Note StringIndexOutOfBoundsException
    int year = Integer.parseInt(input.substring(0, 2));
    int month = Integer.parseInt(input.substring(2, 4));
    System.out.println("year: " +  year + "month: " +  month);
} catch (Exception e) {
    e.printStackTrace();
}

Test

1911

Output

year = 19, month = 11

Or

Scanner io = new Scanner(System.in);
String year = io.next(), month = io.next();
System.out.println("year: " +  year + "month: " +  month);

Test

19 11

Output

year = 19, month = 11
