IsoChronology localDateTime() method in Java with Example
The localDateTime() method of java.time.chrono.IsoChronology class is used to retrieve the local date and time according to Iso calendar system from any other object of temporal accessor.
Syntax:
public LocalDateTime localDateTime( TemporalAccessor temporal)
Parameter: This method takes the object of any temporal accessor as a parameter.
Return Value: This method returns the local date and time according to Iso calendar system from any other object of the temporal accessor.
Below are the examples to illustrate the localDateTime() method:
Example 1:
// Java program to demonstrate // localDateTime() method import java.util.*; import java.io.*; import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] argv) { try { // creating and initializing // LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology // used in LocalDate IsoChronology crono = hidate.getChronology(); // creating and initializing // TemporalAccessor object ZonedDateTime zonedate = ZonedDateTime.parse( "2018-10-25T23:12:31." + "123+02:00[Europe/Paris]" ); // getting LocalDate for the // given TemporalAccessor object // by using localDateTime() method LocalDateTime date = crono.localDateTime(zonedate); // display the result System.out.println( "LocalDateTime is: " + date); } catch (DateTimeException e) { System.out.println( "passed parameter can" + " not form a date" ); System.out.println( "Exception thrown: " + e); } } } |
Output:
LocalDateTime is: 2018-10-25T23:12:31.123
Example 2:
// Java program to demonstrate // localDateTime() method import java.util.*; import java.io.*; import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] argv) { try { // creating and initializing // LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology // used in LocalDate IsoChronology crono = hidate.getChronology(); // creating and initializing // TemporalAccessor object LocalDateTime localdate = LocalDateTime .parse( "2018-12-30T19:34:50.63" ); // getting LocalDate for the // given TemporalAccessor object // by using localDateTime() method LocalDateTime date = crono.localDateTime(localdate); // display the result System.out.println( "LocalDateTime is: " + date); } catch (DateTimeException e) { System.out.println( "passed parameter can" + " not form a date" ); System.out.println( "Exception thrown: " + e); } } } |
Output:
LocalDateTime is: 2018-12-30T19:34:50.630
