// Apache common都有现成解决方案的：

String input = "\n";
assertEquals("", org.apache.commons.lang3.StringUtils.strip(input, "\n\r\t"));

for (Iterator<Calendar> it = DateUtils.iterator(new Date(), DateUtils.RANGE_WEEK_MONDAY); it.hasNext();) {
    print(DateFormatUtils.format(it.next(), DateFormatUtils.ISO_DATE_FORMAT.getPattern()));
}
