JapaneseDate isSupported() method in Java with Example

The isSupported() method of java.time.chrono.JapaneseDate class is used to check if the specific chrono field is supported or not. Syntax:

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 then it returns true otherwise false. Below are the examples to illustrate the isSupported() method: Example 1:

Java

// 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

// 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
