27 Mar, 2020
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:
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
LocalDate hidate = LocalDate.now();
IsoChronology crono = hidate.getChronology();
boolean flag = crono.isLeapYear( 1444 );
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:
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
LocalDate hidate = LocalDate.now();
IsoChronology crono = hidate.getChronology();
boolean flag = crono.isLeapYear( 2005 );
if (flag)
System.out.println( "this is leap year" );
else
System.out.println( "this is non leap year" );
}
}

Output:
this is non leap year
