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

import java.util.Scanner;

class FindMonthList {

public static void main(String[] args){

Scanner sc = new Scanner(System.in);

System.out.println("请输入年份:");

int year = sc.nextInt(); //年份

if (year 1) { //判断非法输入年份

System.out.println("输入错误!");

return;

}

System.out.println("请输入月份:");

int month = sc.nextInt(); //月份

if (month 1 || month 12) { //判断非法输入月份

System.out.println("输入错误!");

return;

}

//输出表头

System.out.println("-------" + year + " 年 " + month + " 月 " + "-------");

System.out.println();

System.out.println("日一二三四五六");

//计算当前年份以前所有天数beforeYearTotalDay;每4年一个闰年,闰年366天,平年365天

int beforeYearTotalDay = ((year - 1) / 4 * 366) + (year-1 - ((year - 1) / 4)) * 365;

int[] arrLeapYear = {0,31,29,31,30,31,30,31,31,30,31,30,31}; //闰年各月天数 int数组

int[] arrNormalYear = {0,31,28,31,30,31,30,31,31,30,31,30,31}; //平年各月天数 int数组

int beforeMonthTotalDay = 0; //定义本年当月之前月份的总天数

if (year % 400 == 0 || (year % 100 != 0 year % 4 == 0)) { //判断当前年份是否是闰年

for (int i = 0 ; i month ; i ++ ) { //for循环计算当月之前总天数

//计算当前月份之前的所有天数

beforeMonthTotalDay = beforeMonthTotalDay + arrLeapYear[i];

}

//判断当月1日是星期几

int totalDay = beforeYearTotalDay + beforeMonthTotalDay + 1;

int week = totalDay % 7;//已知1年1月1日是星期日,即模7得1对应的是星期日

for (int i = 0 ; i (week - 1 + 7) % 7 ; i ++) { //如果写成i (week-1)会出现i-1的情况

System.out.print(" ");//输出开头空白

}

for (int i = 1 ;i = arrLeapYear[month] ;i ++ ) { //for循环输出各月天数

System.out.print(i + " ");

if (i 10 ) { //小于10的数补一个空格,以便打印整齐

System.out.print(" ");

}

if (i % 7 == ((7-(week - 1)) % 7 ) || i == arrLeapYear[month]) {//每逢星期六/尾数换行

System.out.println();

}

} else { //不是闰年就是平年

for (int i = 0 ; i month ; i ++ ) { //for循环计算出当月之前月份总天数

beforeMonthTotalDay = beforeMonthTotalDay + arrNormalYear[i];

}

//判断当月1日是星期几

int totalDay = beforeYearTotalDay + beforeMonthTotalDay + 1;

int week = totalDay % 7;//已知1年1月1日是星期日,即模7得1对应的是星期日

for (int i = 0 ; i (week - 1 + 7) % 7 ; i ++) { //如果写成i (week-1)会出现i-1的情况

System.out.print(" ");//输出开头空白

}

for (int i = 1 ;i = arrNormalYear[month] ;i ++ ) {//for循环输出各月天数

System.out.print(i + " ");

if (i 10 ) { //小于10的数补一个空格,以便打印整齐

System.out.print(" ");

}

if (i % 7 == ((7-(week - 1)) % 7 ) || i == arrNormalYear[month]) {//每逢星期六/尾数换行

System.out.println();

}

显示效果:
