0 0 1 minute read

The isLeapYear() method of java.time.chrono.JapaneseChronology class is used to differentiate between a leap year and a non leap year. If it is a leap year it will return true otherwise false.

Syntax:

public boolean isLeapYear(long prolepticYear)

Parameter: This method takes prolepticYear as a parameter for checking if it is a leap year or not.

Return Value: This method returns Boolean value true if the proleptic year is leap year otherwise false.

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

Example 1:

// Java program to demonstrate
// isLeapYear() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing
        // JapaneseDate Object
        JapaneseDate hidate
            = JapaneseDate.now();
  
        // getting JapaneseChronology
        // used in JapaneseDate
        JapaneseChronology crono
            = hidate.getChronology();
  
        // getting id of this Chronology
        // by using isLeapYear() method
        boolean flag = crono.isLeapYear(1444);
  
        // display the result
        if (flag)
            System.out.println(
                "this is leap year");
        else
            System.out.println(
                "this is non leap year");
    }
}

Output:

this is leap year

Example 2:

// Java program to demonstrate
// isLeapYear() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing
        // JapaneseDate Object
        JapaneseDate hidate
            = JapaneseDate.now();
  
        // getting JapaneseChronology
        // used in JapaneseDate
        JapaneseChronology crono
            = hidate.getChronology();
  
        // getting id of this Chronology
        // by using isLeapYear() method
        boolean flag = crono.isLeapYear(2005);
  
        // display the result
        if (flag)
            System.out.println(
                "this is leap year");
        else
            System.out.println(
                "this is non leap year");
    }
}
