java课程设计简单日历

1、Java 课程设计报告 信101 董兆军 2010314120java课程设计报告题 目 ： JAVA简易时间日历程序学生姓名 ： 董兆军 学 号 ：2010314120 专业班级 ： 信101 指导教师 ： 李红强 课程设计题目 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。系统设计1 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。 2 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

2、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public static class CalendarTable（日历类）public static void main(String args)public static class RollbyJFrame（滚动时间类）public class MyCalendar extends JApplet（主日历框架类）图1：简易日历的程序结构图初始化： 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。 日历描述： （1）public void updateView()改变日期后完成更新

3、界面； （2）抽象类java.util.Calendar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； 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 JavaTM2Platform StandardEd. 6的电子文档，常规的接口与包则省略不屑。/以下是日历程序块中使用的类package fancy; import java.awt.*; import java.a
