The zonedDateTime() method of java.time.chrono.IsoChronology class is used to get the zonal date and time according to Iso calendar system from another TemporalAccessor object.
Syntax:
public ZonedDateTime zonedDateTime(
TemporalAccessor temporal)
Parameter: This method takes the object of any temporal accessor as a parameter.
Return Value: This method returns the zonal date and time according to Iso calendar system from another TemporalAccessor object.
Below are the examples to illustrate the zonedDateTime() method:
Example 1:
// Java program to demonstrate// zonedDateTime() 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 and time for the            // given TemporalAccessor object            // by using zonedDateTime() method            ChronoZonedDateTime<LocalDate> date                = crono.zonedDateTime(zonedate);              // display the result            System.out.println(                "LocalDate and time is: "                + date);        }        catch (DateTimeException e) {            System.out.println(                "passed parameter can"                + " not form a date");            System.out.println(                "Exception thrown: " + e);        }    }} |
LocalDate and time is: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
Example 2:
// Java program to demonstrate// zonedDateTime() 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 and time for the            // given TemporalAccessor object            // by using zonedDateTime() method            ChronoZonedDateTime<LocalDate> date                = crono.zonedDateTime(localdate);              // display the result            System.out.println(                "LocalDate and time is: "                + date);        }        catch (DateTimeException e) {            System.out.println(                "passed parameter can"                + " not form a date");            System.out.println(                "Exception thrown: " + e);        }    }} |
passed parameter can not form a date Exception thrown: java.time.DateTimeException: Unable to obtain ZonedDateTime from TemporalAccessor: 2018-12-30T19:34:50.630 of type java.time.LocalDateTime
