ChronoZonedDateTime isSupported(TemporalField) method in Java with Examples

Last Updated : 29 May, 2019

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:

Java

// 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
