The toInstant() method of a ChronoZonedDateTime class is used to convert this ChronoZonedDateTime to the Instant.
Syntax:
default Instant toInstant()
Parameters: This method do not accepts any parameter.
Return value: This method returns Instant which is the same Instant represented by this ChronoZonedDateTime.
Below programs illustrate the toInstant() method:
Program 1:
import java.time.*;
import java.time.chrono.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
ChronoZonedDateTime time
= ZonedDateTime
.parse(
"2018-12-06T19:21:12.123+05:30[Asia/Calcutta]" );
System.out.println( "ChronoZonedDateTime: "
+ time);
System.out.println( "Instant: "
+ time.toInstant());
}
}
|
Output:
ChronoZonedDateTime: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
Instant: 2018-12-06T13:51:12.123Z
Program 2:
import java.time.*;
import java.time.chrono.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
ChronoZonedDateTime time
= ZonedDateTime.parse(
"1918-10-25T23:12:38.543+02:00[Europe/Paris]" );
System.out.println( "ChronoZonedDateTime: "
+ time);
System.out.println( "Instant: "
+ time.toInstant());
}
}

Output:
ChronoZonedDateTime: 1918-10-25T23:12:38.543Z[Europe/Paris]
Instant: 1918-10-25T23:12:38.543Z
