Below programs illustrate the above method:
Program 1:
import java.time.*;import java.time.Month;import java.time.temporal.ChronoField; class monthEnum { public static void main(String[] args) { // Create a month instance Month month = Month.of(5); // check if the field is valid if (month.isSupported(ChronoField.MONTH_OF_YEAR)) System.out.println("This field is supported!"); else System.out.println("This field is not supported!"); }} |
Output:
This field is supported!
Program 2:
import java.time.*;import java.time.Month;import java.time.temporal.ChronoField; class monthEnum { public static void main(String[] args) { // Create a month instance Month month = Month.of(5); // check if the field is valid if (month.isSupported(ChronoField.DAY_OF_WEEK)) System.out.println("This field is supported!"); else System.out.println("This field is not supported!"); }} |
