JAVA万年历代码

/*

题目:输出任意年份任意月份的日历表(公元后)

思路:

1.已知1年1月1日是星期日,1 % 7 = 1 对应的是星期日,2 % 7 = 2 对应的是星期一,以此类推;

2.计算当年以前所有天数+当年当月1号之前所有天数;

a.年份分平年闰年,平年365天,闰年366天;

b.闰年的判断方法year % 400 == 0 || (year % 100 != 0  year % 4 == 0)若为真,则为闰年否则为平年;

c.定义平年/闰年数组,包含各月天数;

d.遍历数组求和,计算当年当月前总天数;

e.当年以前所有天数+当年当月前总天数+1即为1年1月1日到当年当月1日的总天数;

3.总天数对7取模,根据结果判断当月1号是星期几,输出空白区域;

4.输出当月日历表,逢星期六换行
