输入某年某月某日，判断这一天是这一年的第几天？2020.6.14使用java语言递归方法实现

以下是使用Java语言递归方法实现输入某年某月某日，判断这一天是这一年的第几天的代码：

public class DayOfYear {
    private static int[][] days = {
            {0,31,59,90,120,151,181,212,243,273,304,334},
            {0,31,60,91,121,152,182,213,244,274,305,335}
    };

    public static int getDayOfYear(int year, int month, int day) {
        int leap = 0;
        if (year % 400 == 0 || (year % 4 == 0 && year % 100 != 0)) {
            leap = 1;
        }
        return days[leap][month - 1] + day;
    }

    public static void main(String[] args) {
        int year = 2020;
        int month = 6;
        int day = 14;
        int dayOfYear = getDayOfYear(year, month, day);
        System.out.println(year + "年" + month + "月" + day + "日是这一年的第" + dayOfYear + "天");
    }
}
