Java课程设计报告——桌面日历目录一、需求分析 (2)二、概要设计 (3)三、详细设计 (4)四、调试分析 (9)五、用户说明 (9)六、运行结果 (10)七、附录 (10)一、需求分析选题意义：自上世纪以来，随着电脑的逐渐普及，人们的工作和生活越来越方便和快捷，也使越来越多的人依赖于电脑办公。
而传统的日历记事本显现出在当今时代的不足和局限性，比如不便携带、不便查找、不能自动提醒等等，电脑桌面日历由此孕育而生。
本设计就是针对当前网络上众多的桌面日历，综合其各项基本功能来开发一套属于自己的个性化日历系统。
本设计主要采用NetBeans开发平台，通过java语言来实现记事，日期查询以及日志提醒等工作。
为客户带来方便，同时系统的阐述开发采用的过程及方法。
功能实现：1、通过标签类jLabel显示日、月，程序主体框架。
2、通过按钮类jPanelButton，▲和▼调整年份通过代码“\u25C4”和“"\u25BA"”调整月份。
3、添加鼠标事件，键盘事件，分别可以通过按钮和键盘输入调整显示日期。
4、程序通过读取计算机当前日期，显示当前日期二、概要设计1、取得月份天数private JToggleButton cur=null;//月份天数数组，用来取得当月有多少天// 1 2 3 4 5 6 7 8 9 10 11 12private int[] mm={31,28,31,30,31,30,31,31,30,31,30,31}; //空日期构造函数2、带日期设置的构造函数public JCalendar() {try {jbInit();}catch(Exception e) {e.printStackTrace();}}//带日期设置的构造函数3、带日历输入的构造函数public JCalendar(int year, int month, int day) {cal.set(year, month, day);try {jbInit();}catch (Exception e) {e.printStackTrace();}}//带日历输入的构造函数4、带日期输入的构造函数public JCalendar(GregorianCalendar calendar) {cal=calendar;try {jbInit();}catch (Exception e) {e.printStackTrace();}}//带日期输入的构造函数5、初始化组件public JCalendar(Date date) {cal.setTime(date);try {jbInit();}catch (Exception e) {e.printStackTrace();}}//初始化组件三、详细设计部分代码void jPanelButtonComponentResized(ponentEvent evt){ YearUp.setLocation(0,0);YearDown.setLocation(0,YearUp.getHeight());jPanelButton.setSize(YearUp.getWidth(),YearUp.getHeight()*2); jPanelButton.setPreferredSize(newDimension(YearUp.getWidth(),YearUp.getHeight()*2));jPanelButton.updateUI();}//测试用public static void main(String[] args){JFrame f=new JFrame();f.setContentPane(new JCalendar());f.pack();//f.setResizable(false);f.show();}//增加年份void YearUp_actionPerformed(ActionEvent e) {year++;showYear();showDate();showDays();}//减少年份void YearDown_actionPerformed(ActionEvent e) {year--;showYear();showDate();showDays();}//减少月份void MonthDown_actionPerformed(ActionEvent e) {month--;if(month<0) {month = 11;year--;showYear();}showMonth();showDate();showDays();}//增加月份void MonthUp_actionPerformed(ActionEvent e) {month++;if(month==12) {month=0;year++;showYear();}showMonth();showDate();showDays();}//初始化年月日void iniCalender(){year=cal.get(Calendar.YEAR);month=cal.get(Calendar.MONTH);day=cal.get(Calendar.DAY_OF_MONTH);}//刷新月份void showMonth(){Month.setText(Integer.toString(month+1)+"月");}//刷新年份void showYear(){Year.setText(Integer.toString(year)+"年");}//刷新日期void showDate(){Out.setText(Integer.toString(year)+"-"+Integer.toString(month+1)+"-"+In teger.toString(day));}//重画天数选择面板void showDays() {cal.set(year,month,1);int firstDayOfWeek = cal.get(Calendar.DAY_OF_WEEK); int n=mm[month];if(cal.isLeapYear(year)&&month==1) n++;int i=0;for(;i<firstDayOfWeek-1;i++){days[i].setEnabled(false);days[i].setSelected(false);days[i].setText("");}int d=1;for(;d<=n;d++){days[i].setText(Integer.toString(d));days[i].setEnabled(true);if(d==day) days[i].setSelected(true);else days[i].setSelected(false);;i++;}for(;i<42;i++){days[i].setEnabled(false);days[i].setSelected(false);days[i].setText("");}}//单击年份面板选择整个年份字符串void SelectionYear(){Year.setSelectionStart(0);Year.setSelectionEnd(Year.getText().length());}//单击月份面板选择整个月份字符串void SelectionMonth(){Month.setSelectionStart(0);Month.setSelectionEnd(Month.getText().length());}//月份面板响应鼠标单击事件void Month_mouseClicked(MouseEvent e) {//SelectionMonth();inputMonth();}//检验输入的月份void inputMonth(){String s;if(Month.getText().endsWith("月")){s=Month.getText().substring(0,Month.getText().length()-1); }else s=Month.getText();month=Integer.parseInt(s)-1;this.showMe();}//月份面板键盘敲击事件响应void Month_keyPressed(KeyEvent e) {if(e.getKeyChar()==10)inputMonth();}//年份面板响应鼠标单击事件void Year_mouseClicked(MouseEvent e) {//SelectionYear();inputYear();}//年份键盘敲击事件响应void Year_keyPressed(KeyEvent e) {//System.out.print(new Integer(e.getKeyChar()).byteValue()); if(e.getKeyChar()==10)inputYear();}//检验输入的年份字符串void inputYear() {String s;if(Year.getText().endsWith("年")){s=Year.getText().substring(0,Year.getText().length()-1);}else s=Year.getText();year=Integer.parseInt(s);this.showMe();}//以字符串形式返回日期,yyyy-mm-ddpublic String getDate(){return Out.getText();}//以字符串形式输入日期,yyyy-mm-ddpublic void setDate(String date){if(date!=null){StringTokenizer f = new StringTokenizer(date, "-");if(f.hasMoreTokens())year = Integer.parseInt(f.nextToken());if(f.hasMoreTokens())month = Integer.parseInt(f.nextToken());if(f.hasMoreTokens())day = Integer.parseInt(f.nextToken());cal.set(year,month,day);}this.showMe();}//以日期对象形式输入日期public void setTime(Date date){cal.setTime(date);this.iniCalender();this.showMe();}//返回日期对象public Date getTime(){return cal.getTime();} //返回当前的日public int getDay() {return day;}//设置当前的日public void setDay(int day) {this.day = day;cal.set(this.year,this.month,this.day); this.showMe();}//设置当前的年public void setYear(int year) {this.year = year;cal.set(this.year,this.month,this.day); this.showMe();}//返回当前的年public int getYear() {return year;}//返回当前的月public int getMonth() {return month;}//设置当前的月public void setMonth(int month) {this.month = month;cal.set(this.year,this.month,this.day); this.showMe();}//刷新public void showMe(){this.showDays();this.showMonth();this.showYear();this.showDate();}}public class TestJCalendar {public static void main(String[] args) {JFrame f=new JFrame();f.setContentPane(new JCalendar());f.pack();//f.setResizable(false);f.show();}}四、调试分析1、程序调试初期，按钮无法调整程序日期，后重写Year_mouseClicked(MouseEvent e)添加void showYear()使得功能得以完善。
