public boolean isSupported(TemporalField field)

Parameter: This method accepts the type of Chrono field for checking if that is compatible with that particular date or not.

Return Value: This method returns the boolean value if this date is compatible with the passed field than it returns true otherwise false.



Below are the examples to illustrate the hashCode() method:

Example 1:




// Java program to demonstrate
// isSupported() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate = JapaneseDate.now();
  
            // checking for the
            // given ChronoField
            // by using isSupported() method
            boolean status = hidate.isSupported(
                ChronoField.ERA);
  
            // display the result
            if (status)
                System.out.println(
                    "this field is supported");
            else
                System.out.println(
                    "this field is not supported");
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
this field is supported

Example 2:




// Java program to demonstrate
// isSupported() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate = JapaneseDate.now();
  
            // checking for the
            // given ChronoField
            // by using isSupported() method
            boolean status = hidate.isSupported(
                ChronoField.MICRO_OF_DAY);
  
            // display the result
            if (status)
                System.out.println(
                    "this field is supported");
            else
                System.out.println(
                    "this field is not supported");
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
this field is not supported
