The isSupported() method of ChronoZonedDateTime interface in Java checks if the specified TemporalField is supported or not.
Syntax:
default boolean isSupported(TemporalField field)
Parameter: This method accepts a parameter field which specifies the TemporalField to check, null returns false.
Returns: The function returns true if the field is supported on this date, false if not.
Below programs illustrate the ChronoZonedDateTime.isSupported() method:
Program 1:
// Program to illustrate the isSupported(TemporalField) method import java.util.*;import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoField; public class GfG { public static void main(String[] args) { // Parses the date ChronoZonedDateTime dt1 = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // Prints the date System.out.println(dt1); System.out.println( dt1.isSupported( ChronoField.DAY_OF_WEEK)); }} |
Output:
2018-12-06T19:21:12.123+05:30[Asia/Calcutta] true
