public static String getCurrentMonday() { SimpleDateFormat dateFormat = new SimpleDateFormat(YYYY_MM_DD); int mondayPlus = getMondayPlus(); GregorianCalendar currentDate = new GregorianCalendar(); currentDate.add(GregorianCalendar.DATE, mondayPlus); Date monday = currentDate.getTime(); return dateFormat.format(monday); } private static int getMondayPlus() { Calendar cd = Calendar.getInstance(); // 默认:星期日是第一天 int dayOfWeek = cd.get(Calendar.DAY_OF_WEEK); if (dayOfWeek == 1) { return -6; } else { return 2 - dayOfWeek; } }测试
System.out.println(getCurrentMonday()); 2022-01-03获得当前周周日的日期
public static String getPreviousSunday() { SimpleDateFormat dateFormat = new SimpleDateFormat(YYYY_MM_DD); int mondayPlus = getMondayPlus(); GregorianCalendar currentDate = new GregorianCalendar(); currentDate.add(GregorianCalendar.DATE, mondayPlus + 6); Date sunday = currentDate.getTime(); return dateFormat.format(sunday); }测试
System.out.println(getPreviousSunday()); 2022-01-09
