JAVA編寫一個多功能萬年歷程序
import java.text.SimpleDateFormat; import java.util.Calendar; public class TestDate { public static final String[] weeks = { "日", "一", "二", "三", "四", "五", "六" }; public static void main(String[] args) { Calendar c = Calendar.getInstance(); c.set(Calendar.YEAR,2011);//2011年 c.set(Calendar.MONTH,0);//java中Calendar類，月從0開始， 0代表一月 c.set(Calendar.DATE,1);//1號 int day = c.get(Calendar.DAY_OF_WEEK);//獲致是本周的第幾天地, 1代表星期天...7代表星期六 System.out.println(new SimpleDateFormat( "yyyy-MM-dd ").format(c.getTime())); System.out.println("星期" + weeks[day-1]); } } 把以上測試代碼寫作一個方法 方法的參數(shù)名為年月日， 即可。當然Calendar 還有很多功能，比如一周的第幾天，一年的第幾個月……
JAVA萬年歷代碼
/*
題目:輸出任意年份任意月份的日歷表(公元后)
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(shù)+當年當月1號之前所有天數(shù);
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(shù)組,包含各月天數(shù);
d.遍歷數(shù)組求和,計算當年當月前總天數(shù);
e.當年以前所有天數(shù)+當年當月前總天數(shù)+1即為1年1月1日到當年當月1日的總天數(shù);
3.總天數(shù)對7取模,根據(jù)結果判斷當月1號是星期幾,輸出空白區(qū)域;
4.輸出當月日歷表,逢星期六換行
