下面是使用Java代码获取本年周数的示例: importjava.time.LocalDate;importjava.time.temporal.WeekFields;importjava.util.Locale;publicclassWeekUtil{publicstaticintgetWeekCountInYear(){WeekFieldsweekFields=WeekFields.of(Locale.getDefault());LocalDatenow=LocalDate.now();LocalDatefirstDayOfYear=now.withDayOfYear(...
通过下即可得到：import java.util.Calendar;public class Tesat3 {public static void main(String[] args) {Calendar c=Calendar.getInstance();int i = c.get(Calendar.WEEK_OF_YEAR);System.out.println(i);}}cal.setFirstDayOfWeek(Calendar.MONDAY); 设置星期一为第一天
Calendar calendar =Calendar.getInstance();//设置星期一为一周开始的第一天calendar.setFirstDayOfWeek(Calendar.MONDAY);//获得当前的时间戳calendar.setTimeInMillis(System.currentTimeMillis());//获得当前日期属于今年的第几周intweekOfYear = calendar.get(Calendar.WEEK_OF_YEAR); 使用MySQL函数YEARWEEK和WEEKOFYEAR...
1//取得日期是某年的第几周2publicstaticintgetWeekOfYear(Date date){3Calendar cal =Calendar.getInstance();4cal.setTime(date);5intweek_of_year =cal.get(Calendar.WEEK_OF_YEAR);6returnweek_of_year;7} 3、得到某年的某个月有多少天
WEEK_OF_YEAR) == cal2.get(Calendar.WEEK_OF_YEAR)) return true; } else if (1 == subYear && 11 == cal2.get(Calendar.MONTH)) { // 如果12月的最后一周横跨来年第一周的话则最后一周即算做来年的第一周 if (cal1.get(Calendar.WEEK_OF_YEAR) == cal2.get(Calendar.WEEK_OF_YEAR)) ...
get(Calendar.WEEK_OF_YEAR); calendar.setTime(time); int paramWeek = calendar.get(Calendar.WEEK_OF_YEAR); if (paramWeek == currentWeek) { return true; } return false; } //判断选择的日期是否是本月 public static boolean isThisMonth(Date time) { return isThisTime(time, "yyyy-MM"); ...
get(Calendar.WEEK_OF_YEAR); System.out.println("当前周数为:" + week); // 设置日期为下个月 calendar.add(Calendar.MONTH, 1); System.out.println("下个月的月份为:" + (calendar.get(Calendar.MONTH) + 1)); // 设置日期为下周 calendar.add(Calendar.WEEK_OF_YEAR, 1); System.out.println...
LocalDate localDate=LocalDate.now();intyear=localDate.get(ChronoField.YEAR);//得到年份intmonth=localDate.get(ChronoField.MONTH_OF_YEAR);//得到月份intday=localDate.get(ChronoField.DAY_OF_MONTH);//得到当月中第几天intweekOfMonth=localDate.get(ChronoField.ALIGNED_WEEK_OF_MONTH);//得到当月的第几...
2016-10-10 16:34 −1. WEEK_OF_YEAR 一年中的第几周 由于西方的一周指的是:星期日-星期六,星期日是一周的第一天,星期六是一周的最后一天, 所以,使用 calendar.get(Calendar.WEEK_OF_YEAR) 时应该注意一周的开始应该是哪一天 如果一周的开始是星期一,... ...
