使用Java创建简单的日历应用程序-一个实战教程日历应用程序是一个有用的工具，它允许用户记录和管理事件、约会和提醒。

在这个实战博客中，我们将创建一个Java日历应用程序，演示如何使用Java编程语言和图形用户界面（GUI）库来实现事件管理和日期选择功能。

以下是本实战博客的主要内容：项目概述准备工作创建Java项目设计GUI界面实现日历视图添加事件管理功能总结让我们开始吧！1. 项目概述在本项目中，我们将创建一个简单的Java日历应用程序，它包括以下主要功能：显示日历界面，允许用户选择日期。

在日历中标记已经安排的事件和约会。

允许用户添加、编辑和删除事件。

提供事件的日期和时间提醒功能。

我们将使用Java编程语言和Swing GUI库来构建这个日历应用程序。

2. 准备工作在开始之前，确保您的开发环境已设置好。

我们将使用Java编程语言和Swing库来构建日历应用程序，不需要额外的工具或库。

3. 创建Java项目首先，创建一个新的Java项目，您可以使用任何Java集成开发环境（IDE）来完成此操作。

在项目中，我们将创建Java类来实现日历应用程序。

4. 设计GUI界面我们将创建一个简单的Swing GUI界面，用于显示日历界面和事件列表。

创建一个Java类，例如CalendarApp，并在其中创建GUI界面。

用java做一个简单的日历简单日历1：第一步先求每个月的第一天是星期几-----1900年1月1日--2014年9月1日是星期几呢？就是把这之间的天数加起来在对7求余，结果是多少就是星期几2：求当月有多少天3：在对日历进行排位一：效果图如下所示：二：具体实现代码如下：import java.util.Scanner;public class Calendar {/*** @param args*/public static void main(String[] args) {// TODO Auto-generated method stubScanner input=new Scanner(System.in);System.out.println("----万年历-----");System.out.println("请输入年份：");int year=input.nextInt();System.out.println("请输入月份：");int month=input.nextInt();int sumDay=0;int monthDay=0;//输入的月份天数；for(int oldYear=1900;oldYear<year;oldyear++)< bdsfid="90" p=""></year;oldyear++)<>{if(oldYear%4==0&&oldYear%100!=0||oldYear%400= =0) {sumDay+=366;if(month==2){monthDay=29;}else{if(month==4||month==6||month==9||month==11) {monthDay=30;}else{monthDay=31;}}}else{sumDay+=365;if(month==2){monthDay=28;}else{if(month==4||month==6||month==9||month==11) { monthDay=30;else{monthDay=31;}}}}for(int i=1;i<month;i++)< bdsfid="131" p=""></month;i++)<>{if(i==2){if(year%4==0&&year%100!=0||year%400==0) {sumDay+=29;}else{sumDay+=28;}}else{if(i==4||i==6||i==9||i==11){sumDay+=30;}else{sumDay+=31;}}sumDay+=1;int ofWeek=0;//星期几ofWeek=sumDay%7;//System.out.println("一共多少天："+sumDay);//System.out.println("今天是星期几："+ofWeek);//System.out.println("这个月一共多少天："+monthDay); System.out.println("一\二\三\四\五\六\日");for(int i=1;i<=7;i++){if(ofWeek==0){ofWeek=7;}if(ofWeek==i){for(int j=1;j<=monthDay;j++){System.out.print(j+"\");if((ofWeek+j-1)%7==0){System.out.print("\");}}}else{System.out.print("\");}} }。

课程设计题目2. 题目说明通过编写一个基于JAVA的应用系统综合实例，自定义一个日历组件显示日期和时间并进行适当的功能扩充，实践Java语言编程技术。

3. 系统设计设计目标一个完整的程序应具有以下功能：1）显示当月日历、当前日期、当前时间；2）可查寻任意月以及任意年的日历；3）使用图形化界面能够弹出对话框；5）正常退出程序。

设计思想设计一个类用来构成日历系统的主窗口，然后编写一个框架类显示时间和提示信息。

在设计中应用了多种容器和控件。

系统模块划分图1：简易日历的程序结构图2.3.1初始化：public void init()完成界面初始化，形成一个以挂历形式显示当前日期的窗口。

2.3.2 日历描述：?? （1）public void updateView()改变日期后完成更新界面；? （2）获取系统日期并传递日期数据而且在人工改变日期后得出当天是周几；? （3）public static void main(String[] args)主函数完成系统各算法的调用并对主窗口的一些属性进行设置；2.3.3 滚动时间：? ? 将时间以文本的形式在文本框中滚动播出，并能改变滚动的速度。

4. 使用类及接口仅仅简单说明类的功能，详细资料请参看《JavaTM?2?Platform Standard?Ed. 6》的电子文档，常规的接口与包则省略不屑。

;import .*; ;运行结果与分析图2：初始界面显示日历。
