Java swing日历控件，界面精美，使用方便，能用于个人作品首先，声明一点，这个控件是我从一套据说价值九百多美元的swing类包中提取出来，并加以修改的，所以：
一，你不能把该控件用于任何商业产品中。

二，该控件没有源代码。

（DatePicker.java除外，这个是我加进去的）
三，该控件可以用于你的个人作品中。

截图如下：
使用之前请把datepicker.jar导入classpath中
使用方法如下：
DatePicker datepick = new DatePicker();
或者
datepick = new DatePicker(date,DefaultFormat,font,dimension);//自定义参数值
//各参数含义如下
//参数1 设置该控件的初始值（可选）
//参数2 设置日期的格式（可选）
//参数3 设置该控件的字体（可选）
//参数3 设置该控件的大小（可选）
//该控件继承自JComponent ，它继承了Jcomponent的属性
datepick.setTimePanleVisible(true);//设置时钟面板可见
atepick.setHightlightdays(hilightDays, Color.red);//设置一个月份中需要高亮显示的日子
datepick.setDisableddays(disabledDays);//设置一个月份中不需要的日子，呈灰色显示。

calendarview 用法CalendarView 是一个展示日历的控件，可以通过在布局文件中使用<CalendarView>标签来添加。

同时还可以通过代码来动态设置属性和监听事件。

以下是一些常用方法和属性的使用方法：1. 设置选中日期的最小值和最大值：```javaCalendarView calendarView = findViewById(R.id.calendarView); calendarView.setMinDate(minDate.getTime()); // 设置最小日期calendarView.setMaxDate(maxDate.getTime()); // 设置最大日期```2. 监听日期选中事件：```javaCalendarView calendarView = findViewById(R.id.calendarView); calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {@Overridepublic void onSelectedDayChange(@NonNull CalendarView view, int year, int month, int dayOfMonth) {// 处理选中日期的逻辑}});```3. 设置是否显示周数：```javaCalendarView calendarView = findViewById(R.id.calendarView); calendarView.setShowWeekNumber(true); // 显示周数calendarView.setShowWeekNumber(false); // 不显示周数```4. 设置选中日期的背景色：```javaCalendarView calendarView = findViewById(R.id.calendarView);// 自定义选中日期的背景calendarView.setDateTextAppearance(R.style.SelectedDateStyle);// 或者使用系统默认的选中背景calendarView.setDateTextAppearance(android.R.style.TextAppear ance_DeviceDefault_Widget_DatePicker_Day_Selected);```5. 获取当前选中的日期：```javaCalendarView calendarView = findViewById(R.id.calendarView); long selectedDate = calendarView.getDate(); // 获取当前选中的日期，单位为毫秒```这些只是 CalendarView 的一些常用方法和属性，还有其他一些属性和方法可以根据需要进行查阅和使用。

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("\");}} }。

JavaWeb项⽬FullCalendar⽇历插件使⽤的⽰例代码本⽂介绍了JavaWeb项⽬FullCalendar⽇历插件使⽤的⽰例代码，分享给⼤家，具体如下：使⽤FullCalendar需要引⽤的⽂件1.css⽂件2.js⽂件<link href="${base}/assets/global/plugins/fullcalendar/fullcalendar.min.css" rel="external nofollow" rel="stylesheet" type="text/css" /><script src="${base}/assets/global/plugins/fullcalendar/fullcalendar.min.js"type="text/javascript"></script>⽣成⽇历主界⾯FullCalendar·⾥有个events属性，可以从数据库查询数据动态添加事项events: function(start,end,timezone, callback) {//当前⽇期var date = this.getDate().format('YYYY-MM-DD');$.ajax({url: ctx + "/teach/attend-getCalendarEventsByClazzId.do",dataType: 'json',data: {calendarClazzId : function(){return calendarClazzId;},date : date},success: function(result) {var events = [];$.each(result,function(index,r){var beginTime = r.dateTime.substring(0,11) + r.beginTime.substring(11,20);var endTime = r.dateTime.substring(0,11) + r.endTime.substring(11,20);if(r.numbers != 0) {events.push({title : r.numbers + "⼈缺勤",id : r.id,start : beginTime,end : endTime,backgroundColor : r.numbers >= 3 ? Metronic.getBrandColor('red') :Metronic.getBrandColor('yellow')});} else {events.push({title : "全部出勤",id : r.id,start : beginTime,end : endTime,backgroundColor : Metronic.getBrandColor('green')});}})callback(events);}});},可以给传递到后台的参数重新赋值，并刷新页⾯事项，可以调⽤如下代码：$('#calendar').fullCalendar('refetchEvents');没选择班级之前默认⽇历界⾯选择不同的班级，ajax会根据不同的班级id以及当前⽇期到后台查询事项并刷新\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。
