/**

public Date lastFirday() {

//作用防止周日得到本周日期

Calendar calendar = Calendar.getInstance();

while (calendar.get(Calendar.DAY_OF_WEEK) != Calendar.MONDAY) {

}

int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK) - 1;

int offset = 7 - dayOfWeek;

calendar.add(Calendar.DATE, offset - 9);

return DateTimeUtil.getFirstDayOfWeek(calendar.getTime(), 6);//這是從上周日開(kāi)始數(shù)的到本周五為6
