date4j是一个用于简化日期和时间操作的Java工具。可以替换java.util.Date。

DateTime dateAndTime = new DateTime("2010-01-19 23:59:59");
DateTime dateAndTime = new DateTime("2010-01-19 23:59:59.123456789");
DateTime dateOnly = new DateTime("2010-01-19");
DateTime timeOnly = new DateTime("23:59:59");
DateTime dateOnly = DateTime.forDateOnly(2010,01,19);
DateTime timeOnly = DateTime.forTimeOnly(23,59,59,0);

DateTime dt = new DateTime("2010-01-15 13:59:15");
boolean leap = dt.isLeapYear(); //false
dt.getNumDaysInMonth(); //31
dt.getStartOfMonth(); //2010-01-01, 00:00:00.000000000
dt.getEndOfDay(); //2010-01-15, 23:59:59.999999999
dt.format("YYYY-MM-DD"); //formats as '2010-01-15'
dt.plusDays(30); //30 days after Jan 15
dt.numDaysFrom(someDate); //returns an int
dueDate.lt(someDate); //less-than
dueDate.lteq(someDate); //less-than-or-equal-to
