All you need is available in the SimpleDateFormat class.

public static void main(String[] args) throws Exception {
    SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM");
    SimpleDateFormat sdf2 = new SimpleDateFormat("MMM-yy");

    String s = "2008-04";
    Date d = sdf1.parse(s);
    String s2 = sdf2.format(d);
    
    System.out.println("raw:       " s);
    System.out.println("parsed:    " d);
    System.out.println("formatted: " s2);
}

The output will be:

raw:       2008-04
parsed:    Tue Apr 01 00:00:00 CEST 2008
formatted: Apr-08

Using Java 8 API:

YearMonth yearMonth = YearMonth.parse("2008-04");
String formatted = yearMonth.format(DateTimeFormatter.ofPattern("MMM-uu", Locale.ROOT));
System.out.println(formatted);
