如何用java語言 寫出一個萬年曆呢？ 要求自己輸入年份 自動出現月 日 以及對應的星期
如果要月曆，只要把月份循環那裡修改下，直接調用月曆方法既可

JAVA萬年曆代碼
/*
題目:輸出任意年份任意月份的日曆表(公元後)
思路:
1.已知1年1月1日是星期日,1 % 7 = 1 對應的是星期日,2 % 7 = 2 對應的是星期一,以此類推;
2.計算當年以前所有天數+當年當月1號之前所有天數;
a.年份分平年閏年,平年365天,閏年366天;
b.閏年的判斷方法year % 400 == 0 || (year % 100 != 0 year % 4 == 0)若為真,則為閏年否則為平年;
c.定義平年/閏年數組,包含各月天數;
d.遍曆數組求和,計算當年當月前總天數;
e.當年以前所有天數+當年當月前總天數+1即為1年1月1日到當年當月1日的總天數;
3.總天數對7取模,根據結果判斷當月1號是星期幾,輸出空白區域;
4.輸出當月日曆表,逢星期六換行
