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)); } } |
