Java如何判断指定年份是否为闰年呢?

Java8中判断闰年的方法
      使用Calendar对象的isLeapYear()方法
      即可判断一个年份是否为闰年

package com.java265.example.datetime;

import java.time.LocalDate;
import java.time.Month;
import java.time.Year;
import java.time.temporal.ChronoField;

public class YearIsLeapExample {
    public static void main(String[] args) {
        // 使用java.time.LocalDate类。
        LocalDate now = LocalDate.now();
        boolean isLeap = now.isLeapYear();
        System.out.printf("Year %d, leap year = %s%n", now.getYear(), isLeap);

        LocalDate date = LocalDate.of(2012, Month.JANUARY, 1);
        isLeap = date.isLeapYear();
        System.out.printf("Year %d, leap year = %s%n", date.getYear(), isLeap);

        // 使用java.time.Year类。
        Year year = Year.now();
        isLeap = year.isLeap();
        System.out.printf("Year %d, leap year = %s%n", year.getValue(), isLeap);

        Year anotherYear = Year.of(2012);
        isLeap = anotherYear.isLeap();
        System.out.printf("Year %d, leap year = %s%n", anotherYear.get(ChronoField.YEAR), isLeap);
    }
}

-----运行以上代码，将输出以下信息
Year 2015, leap year = false
Year 2012, leap year = true
Year 2015, leap year = false
Year 2012, leap year = true
