The isSupported(TemporalUnit) method of YearMonth class is used to Check if the specified TemporalUnit is supported by YearMonth class. Actually, this method checks if we can apply addition or subtraction operation using the passed unit to the specified unit this YearMonth. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.
The supported units of ChronoUnit(Temporalunit) are:
- MONTHS
- YEARS
- DECADES
- CENTURIES
- MILLENNIA
- ERAS
All other ChronoUnit instances will return false.
Syntax:
public boolean isSupported(TemporalUnit unit)
Parameters: This method accepts only one parameter unit which represents the TemporalUnit to check.
Return Value: This method returns a boolean value true if the unit is supported on this YearMonth, false if not.
Below programs illustrate the isSupported(TemporalUnit) method:
Program 1:
// Java program to demonstrate// YearMonth.isSupported(TemporalUnit) method import java.time.*;import java.time.temporal.*; public class GFG { public static void main(String[] args) { // Create a YearMonth object YearMonth thisYearMonth = YearMonth.of(2017, 8); // print instance System.out.println("YearMonth :" + thisYearMonth); // apply isSupported() method boolean value = thisYearMonth.isSupported( ChronoUnit.MONTHS); // print result System.out.println("MONTHS unit is supported by YearMonth class: " + value); }} |
YearMonth :2017-08 MONTHS unit is supported by YearMonth class: true
Program 2:
// Java program to demonstrate// YearMonth.isSupported(TemporalUnit) method import java.time.*;import java.time.temporal.*; public class GFG { public static void main(String[] args) { // create a YearMonth object YearMonth thisYearMonth = YearMonth.of(2022, 12); // print instance System.out.println("YearMonth :" + thisYearMonth); // apply isSupported() method boolean value = thisYearMonth.isSupported( ChronoUnit.MILLENNIA); // print result System.out.println("MILLENNIA unit is supported: " + value); }} |
YearMonth :2022-12 MILLENNIA unit is supported: true
