Current date
Localdate localdate = Localdate.now ();


Localdate localDate1 = localdate.of (2017, 11, 10);


Localdate LocalDate2 = localdate.of (2017, 11, 10);
The current year
System.out.println (Localdate.getyear ());
The current month
System.out.println (Localdate.getmonth ());
The current month
System.out.println (Localdate.getmonthvalue ());
The current date is the day of the week
System.out.println (Localdate.getdayofweek ());
The current number of days in a year is the first day
System.out.println (Localdate.getdayofyear ());
The current date is the day ordinal of the month
System.out.println (Localdate.getdayofmonth ());
Number of days per month
System.out.println (Localdate.lengthofmonth ());
How many days are there in this year
System.out.println (Localdate.lengthofyear ());
Whether it is a leap year
System.out.println (Localdate.isleapyear ());
Current date minus one months
System.out.println (localdate.minusmonths (1));
Current date minus one year
System.out.println (Localdate.minusyears (1));
Current date minus one weeks
System.out.println (Localdate.minusweeks (1));
System.out.println (localdate.min);


System.out.println (Localdate.max);
The judgment of time is judged successively
System.out.println (Localdate.isbefore (localdate.minusmonths (1)));
System.out.println (Localdate.isbefore (localdate.plusmonths (1)));
System.out.println (Localdate.isafter (localDate1));


Modifies the specified local date, gets the new object, and specifies a time change on the original object
Localdate localdate1 = localdate.withdayofmonth (1);
Localdate Localdate2 = localdate.withdayofyear (1);
Localdate localdate3 = localdate.withmonth (1);
Localdate localdate4 = localdate.withyear (2018);


System.out.println (LOCALDATE1);
System.out.println (LOCALDATE2);
System.out.println (Localdate3);
System.out.println (LOCALDATE4);


Localdate today = Localdate.now ();
Take the 1th day of the Month:
Localdate firstdayofthismonth = Today.with (Temporaladjusters.firstdayofmonth ());
Take the 2nd day of the Month:
Localdate seconddayofthismonth = Today.withdayofmonth (2);
Take the last day of this month, no more calculation is 28,29,30 or 31:
Localdate lastdayofthismonth = Today.with (Temporaladjusters.lastdayofmonth ());
Take off one day:
Localdate firstDayOf2015 = lastdayofthismonth.plusdays (1);
Take the first Monday of January 2017
Localdate firstMondayOf2015 = Localdate.parse ("2017-01-01"). With (
Temporaladjusters.firstinmonth (Dayofweek.monday));
Compare two time equals
System.out.println (Localdate1.equals (LocalDate2));
System.out.println (Localdate1.equals (Localdate2));


Compares the size of two times, returns the difference between the days of the year, the month, and the day
System.out.println (Localdate1.compareto (LocalDate2));
System.out.println (Localdate1.compareto (Localdate2));


Two days, years, months, etc.
Long days = Localdate2.until (Localdate4, chronounit.days);
Long hour = Localdate2.until (Localdate4, chronounit.years);
System.out.println (days);
System.out.println (hour);
