LocalDate is an immutable datetime class representing a date without a time zone.
//LocalDate是一个不可变的datetime类代表一个日期没有一个时区。
public static DateTimeZone getDefault() { DateTimeZone zone = cDefault.get(); if (zone == null) { try { try { String id = System.getProperty("user.timezone"); if (id != null) { // null check avoids stack overflow zone = forID(id); } } catch (RuntimeException ex) { // ignored } if (zone == null) { zone = forTimeZone(TimeZone.getDefault()); } } catch (IllegalArgumentException ex) { // ignored } if (zone == null) { zone = UTC; } if (!cDefault.compareAndSet(null, zone)) { zone = cDefault.get(); } } return zone; } 复制代码
时间示例:
public static LocalDateRange getThisMonth(TimeZone timeZone) { DateTimeZone tz = DateTimeZone.forTimeZone(timeZone);//时区Asia/Shanghai MutableDateTime mdt = new MutableDateTime(tz); mdt.setDayOfMonth(2);//当月的第一天 resetDayTime(mdt);// LocalDate from = mdt.toDateTime().toLocalDate();//2019-04-01 mdt.addMonths(1);//增加一月 mdt.setDayOfMonth(1);增加一月的某一天 resetDayTime(mdt); mdt.addMillis(-1);2019-05-01 改变为2019-04-30 LocalDate to = mdt.toDateTime().toLocalDate();//2019-04-30 return new LocalDateRange(DateUtils.LocaLDateToInt(from), DateUtils.LocaLDateToInt(to)); } 复制代码
public static int LocaLDateToInt(LocalDate date) { return date.getYear() * 10000 + date.getMonthOfYear() * 100 + date.getDayOfMonth(); } 复制代码
public final class LocalDate extends BaseLocal implements ReadablePartial, Serializable { 复制代码
