原文:https://www . geesforgeks . org/isochronomics-islapyear-method-in-Java-with-example/
Java . time . chrono . isochronomics 类的IsLapyear()方法用于区分闰年和非闰年。如果是闰年，它将返回真或假。
语法:
public boolean isLeapYear(long prolepticYear)
参数:该方法以普理年为参数，检查是否为闰年。
返回值:如果前一年是闰年，该方法返回布尔值 true，否则返回 false。
以下是说明方法的示例:
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 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");
}
}
输出:
this is leap year
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 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");
}
}
输出:
this is non leap year
