java中,一段万年历代码,跑起来总是差4天,修改之后也只能让一部分月份的显示正确,代码如下
我改造了一下你的代码 :
package com.mikuma.calendar;
import java.util.GregorianCalendar;
import java.util.Scanner;
public class Calendar{
public static void main(String[] args){
int year = 0;
int month = 0;
Scanner scanner = new Scanner(System.in);
System.out.println("请输入您要查询的年份");
year = scanner.nextInt();
System.out.println("请输入您要查询的月份");
while (true){
month = scanner.nextInt();
if (month 0 || month 12){
System.out.println("月份输入有误,请重新输入");
}else{
break;
}
}
printPermanentCalendar(year, month);
}
/**
* 输出万年历
*
* @param year
* @param month
*/
private static void printPermanentCalendar(int year,int month){
int days = 0;
int totaldays = 0;//获取1990年至查询的年份的天数
for (int i = 1900; i year; i++){
totaldays = totaldays + (isLeapYear(i) ? 366 : 365);
}
int beforedays = 0;//到指定月份的天数
for (int i = 1; i = month; i++){
switch (i) {
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
days = 31;
break;
case 4:
case 6:
case 9:
case 11:
days = 30;
break;
case 2:
days = isLeapYear(year) ? 29 : 28;
break;
default:
break;
}
if (i month){
beforedays = beforedays + days;
}
}
totaldays = totaldays + beforedays;//总计天数,以判断周几;
int weekDay = 0;
int temp = (1 + totaldays) % 7;
if (temp == 0){//1990年1月1日星期一,据此日0天星期一,以此类推
weekDay = 0;
}else{
weekDay = temp;
}
System.out.println("星期日\t星期一\t星期二\t星期三\t星期四\t星期五\t星期六");
for (int i = 0; i weekDay; i++){
System.out.print("\t");
}
for (int i = 1; i = days; i++){
System.out.print(i + "\t");
if ((totaldays + i) % 7 == 6){
System.out.print("\n");
}
}
}
private static boolean isLeapYear(int year){
return new GregorianCalendar().isLeapYear(year);
}
}
运行:
对比了下 360日历:
结果正确
我们再测试下 2017 年 2月
对比 360 日历
也是正确
编写 万年历java代码例如1900年一月一日是星期一。
import java.util.Calendar;
import java.util.Date;
import java.util.Scanner;
public class MyCalendar
{
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
String reg = "^(\\d+)[^\\d]+((0?[1-9])|(1[012]))$";
while(true)
{
System.out.println("输入年月(年和月用非数字隔开:如2015.1)(什么都不输入直接退出)");
String line = scanner.nextLine().trim();
if("".equals(line))
{
scanner.close();
break;
}
if(!line.matches(reg))
{
continue;
}
int year = Integer.parseInt(line.replaceAll(reg, "$1"));
int month = Integer.parseInt(line.replaceAll(reg, "$2"));
System.out.println("日\t一\t二\t三\t四\t五\t六");
Calendar calendar = Calendar.getInstance();
// 这个月的1号是星期几
calendar.set(year, month - 1, 1);
int day = calendar.get(Calendar.DAY_OF_WEEK);
int start = Calendar.SUNDAY;
calendar.add(Calendar.DATE, -day + start);
while(start day)
{
System.out.print(calendar.get(Calendar.DATE) + "\t");
calendar.add(Calendar.DATE, 1);
start++;
}
calendar.set(year, month - 1, 1);
Date now = calendar.getTime();
calendar.set(year, month, 1);
Date next = calendar.getTime();
for(Date cur = now; cur.before(next);)
{
calendar.setTime(cur);
int x = calendar.get(Calendar.DATE);
String tmp = x 10 ? "0" + x : x + "";
System.out.print(tmp + "\t");
if(calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)
{
System.out.println();
}
calendar.add(Calendar.DATE, 1);
cur = calendar.getTime();
}
calendar.add(Calendar.DATE, -1);
int to = calendar.get(Calendar.DAY_OF_WEEK);
int end = Calendar.SATURDAY;
while(to end)
{
calendar.add(Calendar.DATE, 1);
int x = calendar.get(Calendar.DATE);
String tmp = x 10 ? "0" + x : x + "";
System.out.print(tmp + "\t");
to++;
}
System.out.println();
}
}
}
JAVA程序设计万年历怎么写?
没分的话……就只给你个代码吧……这个是用比较简单的语句写的:
import java.util.Scanner;
public class PrintCalendar {
/**
* 打印日历
* @param args
*/
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入年:");
int year = input.nextInt();
System.out.println("请输入月:");
int month = input.nextInt();
//定义变量,存储该月多少天
int daysOfMonth = 0;
//计算该月多少天
switch(month)
{
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
daysOfMonth = 31;
break;
case 2:
if(year % 400 == 0 || (year % 4 == 0 year % 100 != 0))
{
daysOfMonth = 29;
}else
{
daysOfMonth = 28;
}
break;
default:
daysOfMonth = 30;
}
//System.out.println("该月"+daysOfMonth+"天");
//计算从1099.01.01到输入的年一共过去了多少天
//定义变量,存储总天数
int totalDays = 0;
for(int i=1900; iyear; i++)
{
if(i % 400 == 0 || (i % 4 == 0 i % 100 != 0))
{
totalDays += 366;
}else
{
totalDays += 365;
}
}
//输入的年中,从1月到输入的月,过去了多少天
for(int i=1; imonth; i++)
{
switch(i)
{
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
totalDays += 31;
break;
case 2:
if(year % 400 == 0 || (year % 4 == 0 year % 100 != 0))
{
totalDays += 29;
}else
{
totalDays += 28;
}
break;
default:
totalDays += 30;
}
}
//输入月的1号是周几
int weekDay = totalDays % 7 + 1;
//计算需要打印的空格数
int spaces = weekDay % 7;
//打印日历,先打印日历的头
System.out.println("日\t一\t二\t三\t四\t五\t六");
//定义变量,存储打印了几次
int count = 0;
//打印空格
for(int i=1; i=spaces; i++)
{
System.out.print(" \t");
count++;
}
//打印日历中的每一天
for(int i=1; i=daysOfMonth; i++)
{
System.out.print(i+"\t");
count++;
if(count % 7 == 0)
{
System.out.println();
}
}
}
}
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
