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
