The isSupported(TemporalUnit) method of Year class is used to Check if the specified TemporalUnit is supported by Year class. Actually, this method checks if we can apply addition or subtraction operation using the passed unit to the specified unit this year. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.
The supported units of ChronoUnit(Temporalunit) are:
- 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 the boolean value true if the unit is supported on this Year, false if not.
Below programs illustrate the isSupported(TemporalUnit) method:
Program 1:
// Java program to demonstrate // Year.isSupported(TemporalUnit) method import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// create a Year object
Year year = Year.of( 2019 );
// print instance
System.out.println( "Year :"
+ year);
// apply isSupported() method
boolean value
= year.isSupported(
ChronoUnit.YEARS);
// print result
System.out.println( "YEARS unit is supported by Year class: "
+ value);
}
} |
Year :2019 YEARS unit is supported by Year class: true
Program 2:
// Java program to demonstrate // Year.isSupported(TemporalUnit) method import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// create a Year object
Year year = Year.of( 2022 );
// print instance
System.out.println( "Year :"
+ year);
// apply isSupported() method
boolean value
= year.isSupported(
ChronoUnit.MILLENNIA);
// print result
System.out.println( "MILLENNIA unit is supported: "
+ value);
}

Year :2022 MILLENNIA unit is supported: true
