下面是说明isLeapYear()方法的示例：

示例 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
        // MinguoDate Object
        MinguoDate hidate
            = MinguoDate.now();
  
        // getting MinguoChronology
        // used in MinguoDate
        MinguoChronology crono
            = hidate.getChronology();
  
        // getting id of this Chronology
        // by using isLeapYear() method
        boolean flag = crono.isLeapYear(2016);
  
        // display the result
        if (flag)
            System.out.println(
                "this is leap year");
        else
            System.out.println(
                "this is non leap year");
    }
}

输出：

this is non leap year

示例 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
        // MinguoDate Object
        MinguoDate hidate
            = MinguoDate.now();
  
        // getting MinguoChronology
        // used in MinguoDate
        MinguoChronology crono
            = hidate.getChronology();
  
        // getting id of this Chronology
        // by using isLeapYear() method
        boolean flag = crono.isLeapYear(2017);
  
        // display the result
        if (flag)
            System.out.println(
                "this is leap year");
        else
            System.out.println(
                "this is non leap year");
    }
}

输出：

this is leap year
