Java8 New Date Time Class (3) __java

Java.time Time Date offset class
Java.time the primary class that handles the local date time offset is java.time. Duration, Java.time . Period;

Period-deals with the number of dates based on time.

Duration-deals with the amount of time spent on time.
Duration

Static Construction Method Summary
Static Duration Static Duration Static Duration	between (LocalTime startinclusive,localtime endexclusive) of (Long amount,temporalunit Unit) ofhours (Long hours) ofminutes (Long minutes) Ofseconds (Long seconds)	Use two time difference to generate duration,temporal including localdatetime,zoneddatetime, etc. Create duration with specified Temperalunit
Member Method Summary
+long +duration +long +list<temporalunit> +duration +boolean	tohours ()/Tominutes ()/toseconds () Tomillis ()/Tonanos () Withseconds (Long seconds) Getseconds ()/Getnanos () Getunits () Plus(long amounttoadd,temporaunit unit) plushours (long)/Plusminute(long)/plusseconds(Long) Iszero ()	Converts a duration to a value of the corresponding unit Modify numeric values Get numeric values (effects same as Toseconds,tonanos) Get parameter table To increase or decrease the duration Check whether the value is 0

Period

Static Construction Method Summary
Static Period Static Period Static Period	between (Localdate startinclusive,localdate endexclusive) of (int years,int months,int days) Ofyears (Long hours) ofmonths (Long minutes) Ofdayss (Long seconds)	Use two time difference to generate duration,temporal including localdatetime,zoneddatetime, etc. Creates a period using the specified numeric value
Member Method Summary
+long +period +list<temporalunit> +long +period +boolean	tototalmonths () Withdays(long seconds)/withmonths/withyears Getunits () Getyears ()/getmonths ()/GetDays () Plus(long amounttoadd,temporaunit unit) plusdays (long)/plusmonths(long)/plusyears(Long) Iszero ()	Converts a period to a value of the corresponding unit Modify numeric values Get parameter table Get parameters To increase or decrease the period To determine if it is empty

using the sample

Import java.time.*; ...//Calculate the time difference of two temporal objects localdate date1 = Localdate.of (1997,1,1); Localdate date2 = Localdate.now (); Period Period = Period.between (DATE1,DATE2); System.out.println ("Date1:" +date1+ "\ndate2:" +date2); System.out.println ("Period->years:" +period.getyears () + "months:" +period.getmonths () + "Days:" +period.getdays () ); LocalTime time1 = Localtime.of (0,0,0); LocalTime time2 = Localtime.now (); System.out.println ("time1:" +time1+ "\ntime2:" +time2); Duration Duration = Duration.between (time1,time2); System.out.print ("duration->"); Duration.getunits (). ForEach (Temporalunit-> System.out.print (temporalunit+ ":" +duration.get (temporalunit) + "")) ;
The results are as follows:

date1:1997-01-01 date2:2017-02-28 period->years:20 months:1 days:27 time1:00:00 time2:19:21:16.062 Duration->Se conds:69676 nanos:62000000
