Java实现简单的万年历

Java实现简单的万年历本⽂实例为⼤家分享了Java实现简单万年历的具体代码，供⼤家参考，具体内容如下1 要求1、输⼊年份；2、输⼊⽉份；3、输出某年某⽉的⽇历。

2 思路1、实现从控制台接收年和⽉，判断是否是闰年（判断是否是闰年：能被4整除但不能被100整除；或者能被400整除）；2、计算输⼊⽉份的天数；3、计算该⽉第⼀天是星期⼏；3.1 计算输⼊年份距离1900年1⽉1⽇的天数；3.2 计算输⼊⽉份之前的天数（从当年年初开始）；3.3 将以上两组数据进⾏求和；3.4 已知该⽉之前的天数，计算输⼊⽉份的第⼀天是星期⼏（从1900年1⽉1⽇(星期⼀)开始推算: 星期⼏ = 1 + 天数差 % 7 ）。

4、按格式输出该⽉⽇历。

3 源代码import java.util.Scanner;public class index {//每个⽉的天数public static int monthday(int month, int year) {if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {int[] day = {0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};return day[month];} else {int[] day = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};return day[month];}}//⽉份总天数public static int monthdays(int month, int year) {int totaldays = 0;for (int i = 1; i < month; i++) {totaldays = totaldays + monthday(i, year);}return totaldays;}//距离1900年的年份总天数public static int yeardays(int year){int yeardays = 0;for (int i = 1900;i<year;i++){if ((i % 4 == 0 && i % 100 != 0) || i % 400 == 0) {yeardays = yeardays+366;} else {yeardays = yeardays+365;}}System.out.println(year+"年距离1900年的总天数"+yeardays);return yeardays;}//输出⽇历public static void printCalendar(int month,int year){int totaldays = 0;if (year > 0) {if (month > 0 && month < 13) {//距离1900年1⽉1⽇总天数totaldays = monthdays(month,year)+yeardays(year);System.out.println(year+"年"+month+"⽉1⽇距离1900年的总天数:"+totaldays);System.out.println("\n**********"+year+"年"+month+"⽉的⽇历为**********");System.out.println("⼀\t⼆\t三\t四\t五\t六\t⽇\t");int week = 1+totaldays%7;//根据1⽇为周⼏输出空格for(int i=1;i<week;i++){System.out.print(" \t");}//输⼊具体⽇期for(int i=1;i<=monthday(month,year);i++){System.out.print(i+"\t");if(week==7){week = 1;//重置为星期⼀System.out.println();}else{week++;}}} else {System.out.println("输⼊的⽉份不合法！");}} else {System.out.println("输⼊的年份不合法！");}}//主函数public static void main(String[] args) {Scanner scanner = new Scanner(System.in);System.out.println("***********************欢迎使⽤万年历**************************");System.out.println("*********请选择你需要进⾏的操作（输⼊进⾏操作之前的数字）**********"); System.out.println("********************1.查询某年某⽉的⽇历************************");System.out.println("********************2.结束操作*********************************");System.out.print("\n请选择你需要进⾏的操作：");int a = scanner.nextInt();for (int i=0;i>=0;i++) {switch (a) {case 1:System.out.print("请选择年份：");int year = scanner.nextInt();System.out.print("请选择⽉份：");int month = scanner.nextInt();printCalendar(month, year);System.out.print("\n请选择你需要进⾏的操作：");a = scanner.nextInt();break;case 2:System.out.println("退出程序成功！");return;}}}}4 结果截图注意：我的周⽇是在最后⼀栏以上就是本⽂的全部内容，希望对⼤家的学习有所帮助，也希望⼤家多多⽀持。

用JAVA编万年历和记事本

用JAVA编写万年历！万年历其实可分为5步来做，下面我们来详细分析下步骤：a：先输出提示语句，并接受用户输入的年、月。

b：根据用户输入的年，先判断是否是闰年。

C：根据用户输入的月来判断月的天数。

D：用循环计算用户输入的年份距1900年1月1日的总天数。

E：用循环计算用户输入的月份距输入的年份的1月1日共有多少天。

F：相加D与E的天数，得到总天数。

G：用总天数来计算输入月的第一天的星期数。

H：根据G的值，格式化输出这个月的日历！其实有些步骤是可以合并的，这得靠大家自己的习惯了，下面我们就来一步一步来完成万年历。

<这里只提供讲解，没有源码下载哦！其实大家不必去网上下载，那有意思吗？我们学习是为了什么啊！要下载那就不必来这了！呵呵，发表下自己的看法！>这里大家肯定都能看得懂的，1：这是为了美化，我们编的程序是让别人看的，所以就要输出个标题的。

2：这里就是用来接收用户输入的信息，并赋值给两个变量！这个相信大家都能看得懂！3：这里我们就要开始万年历的真正开发了，看完代码大家都知道这是要进行闰年判断了，这里大家要先明白判断闰年的条件是什么？（条件：这个年首先不是整百年就是最后两位是0的年，因为如果是的话就要除以400了，并且还要能被4整除的或者就是整百年能被400除尽的年是闰年）这里声明了一个boolean值，用来储存是否是闰年，因为咱们后面要用得到的！下面就要进行第二步了，来处理用户输入的月了，看完后大家都明白了吧！这里要用if来判断输入的月份，我们给月份分类，有这几种情况：有31天，有30天，有29天，有28天，下面我们就要想明白每个类的判断条件了？（条件：有31天的月是1、3、5、7、8、10、12，有30天的月是4、6、9、11，剩下就是2月了，它有两种情况，就是根据第一步的boolean值来判断了，如果为true就是29天，为false则是28天了。

）这里用到了一个变量tian，因为咱们后面还要用到的，这些变量可以在做到后面再回来补上的。

Java万年历

J a v a万年历一项目概述：这个项目是一个简单的Java万年历，可以实现所有年份的公历日期的查询，并且在相应的日期做备忘录，以及可以显示当前的日期以及时间。

使用的是Oracle数据库进行连接。

二具体功能介绍：（1）万年历查询：点击图形界面中的上年、下年键用来调整要查询的年份，或者可以直接在上年下年按钮直接的文本框中输入年份（负数表示公元前），以回车结束；点击上月或者下月来调整要查询的月份，然后可以看到这个月的每一天所对应的星期。

（2）Clock功能：在万年历下面显示当前的年月日时分秒，相当于一个时钟的功能。

用Java程序编写万年历程序的设计报告

用Java程序编写万年历程序的设计报告一、引言万年历是一种常见的工具，用于显示特定日期的星期几、农历日期、节气等信息。

本设计报告旨在介绍使用Java编写万年历程序的设计过程和实现细节。

二、需求分析1. 显示当前日期的星期几和农历日期；2. 支持用户输入指定日期，显示该日期的星期几和农历日期；3. 显示当月的日历，并标记当天；4. 支持用户选择不同年份和月份，显示相应的日历；5. 显示当天的节气。

三、设计思路1. 日期计算：使用Java提供的日期和时间类，如`java.util.Calendar`，来进行日期计算和格式化；2. 农历计算：根据农历算法，计算指定日期的农历日期和节气；3. 用户界面：使用Java图形用户界面（GUI）库，如`javax.swing`，来实现用户界面；4. 数据展示：使用文本框、标签等组件来展示日期、星期几、农历日期和节气。

四、程序实现1. 创建Java项目，并导入所需的库；2. 创建主界面窗口，设置布局和组件；3. 添加日期选择器，用于选择年份和月份；4. 添加按钮，用于触发日期查询和切换月份；5. 根据用户选择的日期，计算并显示星期几、农历日期和节气；6. 根据用户选择的年份和月份，计算并显示当月的日历；7. 标记当天的日期；8. 添加事件监听器，处理用户的操作。

五、代码示例```java// 导入所需的库import java.util.Calendar;import java.util.Date;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JPanel;public class CalendarProgram extends JFrame {private JLabel dateLabel;private JLabel weekdayLabel;private JLabel lunarLabel;private JLabel festivalLabel;private JPanel calendarPanel;public CalendarProgram() {// 设置窗口标题和大小setTitle("万年历程序");setSize(800, 600);// 创建主界面布局和组件JPanel mainPanel = new JPanel(); dateLabel = new JLabel();weekdayLabel = new JLabel(); lunarLabel = new JLabel();festivalLabel = new JLabel();calendarPanel = new JPanel();// 将组件添加到主界面布局中 mainPanel.add(dateLabel);mainPanel.add(weekdayLabel); mainPanel.add(lunarLabel);mainPanel.add(festivalLabel);mainPanel.add(calendarPanel); // 设置主界面布局和显示setContentPane(mainPanel);setVisible(true);}public void updateCalendar(Date selectedDate) {// 根据选择的日期更新界面显示Calendar calendar = Calendar.getInstance();calendar.setTime(selectedDate);// 计算并显示星期几、农历日期和节气int weekday = calendar.get(Calendar.DAY_OF_WEEK); String lunarDate = calculateLunarDate(calendar);String festival = calculateFestival(calendar);dateLabel.setText("日期：" + selectedDate.toString()); weekdayLabel.setText("星期几：" + weekday);lunarLabel.setText("农历日期：" + lunarDate);festivalLabel.setText("节气：" + festival);// 计算并显示当月的日历int year = calendar.get(Calendar.YEAR);int month = calendar.get(Calendar.MONTH);int daysInMonth = calculateDaysInMonth(year, month); displayCalendar(year, month, daysInMonth);}private String calculateLunarDate(Calendar calendar) {// 根据农历算法计算农历日期// 实现略}private String calculateFestival(Calendar calendar) {// 根据日期计算节气// 实现略}private int calculateDaysInMonth(int year, int month) {// 计算指定年份和月份的天数// 实现略}private void displayCalendar(int year, int month, int daysInMonth) { // 显示当月的日历// 实现略}public static void main(String[] args) {CalendarProgram program = new CalendarProgram();program.updateCalendar(new Date());}}```六、总结通过使用Java编写万年历程序，我们可以实现日期计算、农历计算和节气计算等功能，并通过图形界面展示给用户。

代码：1import java.util.Scanner;2public class PrintCalendar{3public static void main(String[] args){4 Scanner input=new Scanner(System.in);56 System.out.print("Enter full year(e.g.,2011): ");7int Year=input.nextInt();89 System.out.print("Enter month as a number between 1 and 12: ");10int Month=input.nextInt();1112// int year=inputYear();13//int month=inputMonth();14 printMonth(Year, Month);15 }16/*17 public static int inputYear(){18 boolean flag=true;19 Scanner input=new Scanner(System.in);20 while(flag){21 System.out.print("Enter full year(e.g.,2011): ");22 int iYear=input.nextInt();23 if(iYear>=1800){24 flag = false;25 }26 }27 return iYear;28 }2930 public static int inputMonth(){31 boolean flag=true;32 Scanner input=new Scanner(System.in);33 while(flag){34 System.out.print("Enter month as a number between 1 and 12: ");35 int iMonth=input.nextInt();36 if(iMonth>=1 && iMonth<=12){37 flag = false;38 }39 }40 return iMonth;41 }*/4243public static void printMonth(int year, int month){44 printMonthTitle(year, month);45 printMonthBody(year,month);46 }4748public static void printMonthTitle(int year, int month){49 System.out.println("\t" + getMonthName(month)+"\t" +year);50 System.out.println("-----------------------------------");51 System.out.println("Mon Tue Wed Thu Fri Sat Sun");52 }53public static String getMonthName(int month){54 String monthName="";55switch (month){56case 1: monthName="January"; break;57case 2: monthName="February"; break;58case 3: monthName="March"; break;59case 4: monthName="April"; break;60case 5: monthName="May"; break;61case 6: monthName="June"; break;62case 7: monthName="July"; break;63case 8: monthName="August"; break;64case 9: monthName="September"; break;65case 10: monthName="October"; break;66case 11: monthName="November"; break;67case 12: monthName="December"; break;68 }6970return monthName;71 }7273public static void printMonthBody(int year, int month){7475//Get start day of the week for the first date int the month76int startDay=getStartDay(year,month);7778//Get number of days in the month79int numberOfDaysInMonth = getNumberOfDaysInMonth(year,month);8081//Pad space before the first day of the month82int i=0;83for(i=1; i< startDay; i++){84 System.out.print(" ");85 }86for(i=1; i<=numberOfDaysInMonth;i++){87 System.out.printf("%-4d", i);8889if((i+startDay-1)%7==0)90 System.out.println();91 }92 System.out.println();93 }9495/** Get the start day of month/1/year */96public static int getStartDay(int year, int month){97final int START_DAY_FOR_JAN_1_1800 = 3;9899//Get the total number of days from 1/1/1800 to month/1/year100int totalNumberOfDays= getTotalNumberOfDays(year,month);101102//Return the start day for month/1/year103return (totalNumberOfDays+START_DAY_FOR_JAN_1_1800)%7;104 }105106/** Get the total number of days from January 1, 1800; */107public static int getTotalNumberOfDays(int year, int month){108int total = 0;109110//get total number of days from 1800 to 1/1/year111for(int i = 1800; i<year; i++){112if(isLeapYear(i))113 total = total + 366;114else115 total = total + 365;116 }117118//add days from January to the month prior to the calendar month119for(int i = 0; i<month;i++)120 total +=getNumberOfDaysInMonth(year, i);121122return total;123 }124125/** Get the number of days in a month */126public static int getNumberOfDaysInMonth(int year, int month){127if(month==1||month==3||month==5||month==7||month==8||month==10||month==12) 128return 31;129if(month==4||month==6||month==9||month==11)130return 30;131if(month==2)132return isLeapYear(year)?29:28;133return 0;134 }135136/** Determine if it is a leap year */137public static boolean isLeapYear(int year){138return year % 400 == 0 || (year % 4 == 0 && year % 100 != 0);139 }140 }执⾏效果：。

Java基础之打印万年历的简单实现（案例）

Java基础之打印万年历的简单实现（案例）问题：输⼊年，⽉，打印对应年⽉的⽇历。

⽰例：问题分析：1，⾸先1970年是Unix系统诞⽣的时间，1970年成为Unix的元年，1970年1⽉1号是星期四，现在⼤多的⼿机的⽇历功能只能显⽰到1970年1⽉1⽇这⼀天; 2，要想打印某年某⽉的⽇历，⾸先应该计算出这个⽉1号是星期⼏？解决1号是星期⼏？2.1:先计算出年天数，即截⾄这⼀年1⽉1号的天数，⽤for循环，从1970年开始，闰年+366，平年+365;2.2:计算出⽉天数，即截⾄本⽉1号的天数，⽤for循环，从1⽉份开始，算出⽉天数;2.1.1:⽤到闰年判断，⽤switch来判断返回⽉天数;2.3：⽤年天数加⽉天数，求得本⽉1号距离1970年1⽉1号的总天数，⽤总天数来判断本⽉1号是星期⼏;3，判断本⽉的总天数（⽤到switch语句）;4，打印⽇历;代码实现：⼀个函数实现打印PrintTitle();即实现固定的头部部分;实现Print(参数1，参数2，参数3);即实现打印⽇历主题部分;参数1(计算总天数):计算年天数，计算⽉天数;参数2传递年份;参数3传递⽉份;判断闰年设置独⽴函数;总结：解决问题前⼀定要先分析问题，把⼤问题逐步分成⼩问题，理清逻辑，实现⼩问题的逻辑，整个问题就已经实现了百分之⼋⼗;⾃下⽽上，逐步实现，函数独⽴调⽤;代码实现部分：--------------------------------------------------------以上这篇Java基础之打印万年历的简单实现(案例)就是⼩编分享给⼤家的全部内容了，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。

JAVA打印任意一年年历

public static void main(String arg[]) {

} int day=firstMonth(m); for(int i=1; i<=monthDay(m); i++, day++) {
case 2: if(isLeapYear(year)) return 29; else return 28;
default: return 0;
} }
/*
