In LocalTime class, there are two types of isSupported() method depending upon the parameters passed to it.
isSupported(TemporalField field)
isSupported() method of a LocalTime class used to Check if the specified field is supported by LocalTime class or not means using this method we can check if this LocalTime can be queried for the specified field.
The supported fields of ChronoField are:Â
Â
- NANO_OF_SECOND
- MICRO_OF_SECOND
- MILLI_OF_SECOND
- INSTANT_SECONDS
- SECOND_OF_MINUTE
- NANO_OF_DAY
- MICRO_OF_DAY
- MILLI_OF_DAY
- SECOND_OF_DAY
- MINUTE_OF_HOUR
- MINUTE_OF_DAY
- HOUR_OF_AMPM
- CLOCK_HOUR_OF_AMPM
- HOUR_OF_DAY
- CLOCK_HOUR_OF_DAY
- AMPM_OF_DAY
All other ChronoField instances will return false.
Syntax:Â
public boolean isSupported(TemporalField field)
Parameters: This method accepts one single parameter field which is the field to check.
Return value: This method returns boolean value true if the field is supported on this LocalTime, false if not.
Below programs illustrate the isSupported() method:
Program 1:Â
Â
Java
// Java program to demonstrate// LocalTime.isSupported() methodÂ
import java.time.*;import java.time.temporal.ChronoField;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // create a LocalTime object        LocalTime lt            = LocalTime.parse("19:34:50.63");Â
        // check Milli of Second is supported in LocalTime        boolean value            = lt.isSupported(ChronoField.MILLI_OF_SECOND);Â
        // print result        System.out.println("MilliSecond Field is supported: "                           + value);    }} |
MilliSecond Field is supported: true
isSupported(TemporalUnit unit)
isSupported() method of a LocalTime class used to Check if the specified unit is supported by LocalTime class or not means using this method we can check if this LocalTime can be queried for the specified unit.
The supported fields of ChronoUnit are:Â
Â
- NANOS
- MICROS
- MILLIS
- SECONDS
- MINUTES
- HOURS
- HALF_DAYS
All other ChronoUnit instances will return false.
Syntax:Â
public boolean isSupported(TemporalUnit unit)
Parameters: This method accepts one single parameter unit which is the unit to check.
Return value: This method returns boolean value true if the field is supported on this LocalTime, false if not.
Below programs illustrate the isSupported() method:
Program 1:Â
Â
Java
// Java program to demonstrate// LocalTime.isSupported() methodÂ
import java.time.*;import java.time.temporal.ChronoUnit;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // create a LocalTime object        LocalTime lt            = LocalTime.parse("19:34:50.63");Â
        // check MILLIS ChronoUnit supported in LocalTime        boolean value            = lt.isSupported(ChronoUnit.MILLIS);Â
        // print result        System.out.println("ChronoUnit MILLIS is supported: "                           + value);    }} |
ChronoUnit MILLIS is supported: true
