### Question:
DateUtils { public static int getWeekOfYear(Date d, Locale locale) { Calendar c = Calendar.getInstance(getSafeLocale(locale)); c.setTime(d); return c.get(Calendar.WEEK_OF_YEAR); } private  DateUtils(); static Date getDateNow(); static Date getTimeNow(); static Date addDate(Date date, int years, int months, int days); static Date setDate(Date date, int year, int month, int day); static Date getDate(int year, int month, int day); static Date setTime(Date date, int hours, int minutes, int seconds, int millis); static Date getDateOnly(Date date); static Date parseDate(String sDate, Locale locale); static String formatDate(Date d, Locale locale); static String formatTime(Date d, Locale locale, boolean withSeconds); static String formatDayOfWeek(Date d, Locale locale, boolean longFormat); static String formatMonth(Date d, Locale locale, boolean longFormat); static int getWeekOfYear(Date d, Locale locale); static String formatMonth(int month, Locale locale, boolean longFormat); static String formatYear(Date d, Locale locale);  }### Answer:
@Test public void testGetWeekOfYear() { Calendar cal = simpleCalendar(); int weekOfYear = DateUtils.getWeekOfYear(cal.getTime(), Locale.ITALY); assertEquals(9, weekOfYear); weekOfYear = DateUtils.getWeekOfYear(cal.getTime(), Locale.CHINA); assertEquals(10, weekOfYear); }
