IsoChronology isLeapYear() method in Java with Example
The isLeapYear() method of java.time.chrono.IsoChronology 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 LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology used in LocalDate IsoChronology 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 LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology used in LocalDate IsoChronology 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" ); } } |
Output:
this is non leap year
