获取当前星期几

String[][] strArray = {
  {"MONDAY", "一"}, {"TUESDAY", "二"}, {"WEDNESDAY", "三"}, {"THURSDAY", "四"}, {"FRIDAY", "五"}, {"SATURDAY", "六"}, {"SUNDAY", "日"}};LocalDate currentDate = LocalDate.now();String k = String.valueOf(currentDate.getDayOfWeek());//获取行数for (int i = 0; i < strArray.length; i++) {    if (k.equals(strArray[i][0])) {        k = strArray[i][1];       break;     }}System.out.println("星期" + k);

此种得出的是  k为 “一”到“七”；

要得到别的类型修改 strArray 中的 “一”即可 

例如  ：

String[][] strArray = {
  {"MONDAY", "1"}, {"TUESDAY", "2"}, {"WEDNESDAY", "3"}, {"THURSDAY", "4"}, {"FRIDAY", "5"}, {"SATURDAY ", "6"}, {"SUNDAY", "7"}};

顺便  

LocalDateTime转LocalDate

LocalDateTime now = LocalDateTime.now();now.toLocalDate();
