java日历课程设计报告

. . ..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2.1 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。

2.2 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。

2.3 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）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；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《JavaTM2PlatformStandard Ed. 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.awt.event.*;import java.util.*; //主要用此包中的日期和时间类import javax.swing.*;import javax.swing.event.*;import javax.swing.table.*;//以下是对滚动时间程序块所使用的类和接口，用到定时器类Timerimport java.awt.Color;import java.awt.FlowLayout;import java.awt.event.ActionListener;import java.awt.event.ActionEvent;import java.awt.event.FocusListener;、//用于监听鼠标单击（焦点改变）事件import java.awt.event.FocusEvent;//用于响应鼠标单击（焦点改变）事件、import javax.swing.JFrame;import javax.swing.JTextField;import javax.swing.JSpinner;//让用户从一个有序序列中选择一个数字或者一个对象值的单行输入字段。

二要求内容利用我们所学的编写一个简单的日历表三设计原理运用课堂所学知识和上机课的练习的基础上在Java运行环境JCreaor中编写程序，还有在课外自己学的扫描仪。

四设计目的1.运用我们自学的扫描仪实现我们的操作。

2.该日历可以实现与生活中的日历一样。

3.先随机输入几年，随机输入几月，就能显示当月的天数，每一天的星期第二章编写程序及结果一程序编程Import java.util.Scanner;public class Qsr_2013{public static void main(String[] args){Scanner in=new Scanner(System.in)；System.out.println("请输入月份：");int month=in.nextInt();int sum=0；for(int i=1;i<month;i++){if(i==2){if(year%4==0&&year%100!=0||year%400==0){sum+=29;}else{sum+=28;}}else{if(i==4||i==6||i==9||i==11){sum+=30;}else{sum+=31;}}}sum+=1;int wekday=sum%7;System.out.println("日\t一\t二\t三\t四\t五\t六"); for(int i=1;i<=wekday;i++){System.out.print("\t");}for(int i=1;i<=30;i++){if(sum%7==6){System.out.print(i+"\n");}else{System.out.print(i+"\t");}sum++;}}}二运行结果来两张程序截图先确定下没有错误的2013年输入月份然后运行 1月哦4月来张第三章心得通过这次课程设计，使我灵活应用所学java知识，独立完成问题分析，结合数据结构理论知识，编写程序求解指定问题。

4.设计体会
本次课程设计我决定做日历的设计。

主要考虑到以前时间少课程内容多，JA V A课程基础内容掌握并不是很抓实，而对于设计一个小日历程序，由于其功能简单设计也相对较易，对于我的学习情况比较合适，并且通过设计这样的一个日历小组件，也能使自己对JA V A的一些基础知识掌握的更加牢固。

对于本程序的设计，首先考虑其功能有哪些，需要显示什么，如何进行窗体构建布局，需要用哪些知识点，如相关的类和对象等。

最后，就是根据初步设计的功能和布局构架，考虑用源代码进行实现了。
