What about using [`SimpleDateFormat`](http://developer.android.com/reference/java/text/SimpleDateFormat.html)? — Lion, Jul 17 '12 at 13:23

This is what you are looking for. You have to use SimpleDateFormat. Here is the link: String to date conversion

Of course, using SimpleDateFormat would be better solution, but if you insist and if you know coming style... Then you can simply format it yourself, with some codes like this:

public static String ConvertDate(String valueToFormat) {
      String value = valueToFormat;
      String day = value.substring(value.indexOf("-") + 1, value.indexOf(" "));
      String month = value.substring(0, value.indexOf("-"));
      String time = value.substring(value.indexOf(" ") + 1, value.lenght());

      Calendar c = Calendar.getInstance();
      int year = c.get(Calendar.YEAR);

      // if you want year to appear as only last two items
      year = year % 100;

      value = day + "-" + month + "-" + year + " " + time;
      return value;
}
