Return Value: This method returns the number of days present in a month represented by a particular japanese date.

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

Example 1:

Java

// Java program to demonstrate
// lengthOfMonth() 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();

            // Getting length of a month
            // by using lengthOfMonth() method
            int length = hidate.lengthOfMonth();

            // Display the result
            System.out.println("no of day present: "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

no of day present: 31

Example 2:

Java

// Java program to demonstrate
// lengthOfMonth() 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.of(2020, 06, 23);

            // Getting length of a month
            // by using lengthOfMonth() method
            int length = hidate.lengthOfMonth();

            // Display the result
            System.out.println(
                "no of day present: "
                + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

no of day present: 30
