⑶您好，关于Java程序的问题，万年历插入背景图片
⑷要为万年历插入背景图片，每个月份都采用不同的背景图片，需要在JPanel的paintponent函数内，用g.drawImage方法，把背景图片画在JPanel上。
⑸另外，你的程序有问题年六月没有天。
⑹下面我给你一个例子。(注意:需要把图片文件放在项目名文件夹下)

⑻JS获取指定月份的天数两种实现方法
⑼最近看到一个有意思的试题，正好在需求中也碰到类似的问题，即计算某个月的天数问题。碰到类似问题也许大部分会想是不是还要判断闰年、平年，如果这样想的话就复杂了，下面给出具体的计算方法。获取月份天数方法一：//传入年份和月份获取该年对应月份的天数functiongetMonthDays(year,month){varthisDate=newDate(year,month,);//当天数为js自动处理为上一月的最后一天returnthisDate.getDate();}上面应该时获取月份天数最简单的方法之一了，当Date中参数超出范围时js会自动处理，如果传值小于等于,则日期将会向前推，否则日期将会向后推。下面时MDN原文，也提到了此现象：Note:当Date作为构造函数调用并传入多个参数时，如果数值大于合理范围时（如月份为或者分钟数为，相邻的数值会被调整。比如newDate(,,)等于newDate(,,)，它们都表示日期--（注意月份是从开始的。其他数值也是类似，newDate(,,,,)等于newDate(,,,,)，都表示时间--T::。下面给出几个例子供参考：.参数传入负数.传入大于规定范围的值以上可看出，js本身对日期处理还是比较好的，同时开发人员也可以利用这一点获取想要的结果。获取月份天数方法一：下面就是比较正常的获取方式了，代码：//根据两个月份同一天的差值获取,同样是传入需要获取的对应年份和月份functiongetMonthDays(year,month){varstratDate=newDate(year,month-,),endData=newDate(year,month,);vardays=(endData-stratDate)/(***);returndays;}第二种方式则是根据所求月份和下一个月份某一天的差值获取对应月份的天数。总结以上所述是小编给大家介绍的JS获取指定月份的天数两种方法，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对脚本之家网站的支持！您可能感兴趣的文章:JS获取月份最后天数、最大天数与某日周数的方法JS获取月的最后一天与JS得到一个月份最大天数的实例代码

⒁java编写某年某月有多少天
⒂importjava.util.Scanner;publilassDayOfMonth{publicstaticvoidmain(Stringargs){Scanners=newScanner(System.in);System.out.println(“请输入年“);intyear=s.nextInt();System.out.println(“请输入月“);intmonth=s.nextInt();switch(month){case:case:case:case:case:case:case:System.out.println(year+“年“+month+“月有天“);break;case:case:case:case:System.out.println(year+“年“+month+“月有天“);break;case:if((year%==&&year%!=)||year%==)System.out.println(year+“年月有天“);elseSystem.out.println(year+“年月有天“);break;}}}这样可以了么？
⒃在java中如何编写‘’输出两个月后的今天，是星期几‘’
⒄Scannersc=newScanner(System.in);intday=,month=;do{day=sc.nextInt();//输入星期几（到}while(day《=&&day》);do{month=sc.nextInt();//输入当前几月（到}while(month《=&&month》);sumday=getmonthdays(（month+-（month+/)+getmonthdays((month+)-(month+)/);然后算出总天数%加上星期几（如果超过减去intgetday=sumday%+day;getday=getday》?getday-:getday;publicintgetmonthdays(intmonth){......}//这个方法自己写，用switchcase判断一个月多少天（二月的话还需要输入年份判断是否闰年，闰年则，否则望采纳
⒅用C++怎么算任意两个时间段的天数如年月日到年月日期间有几天
⒆先做个tm结构，然后用mktime变成time_t，两个time_t的差就是之间的秒数，换算天数的话就除*就好了。代码大致上这样,需要time.hstructtmtm={},tm={};tm.tm_year=;tm.tm_mon=;//注意月份是从开始的tm.tm_mday=;//月份日期是从开始的tm.tm_year=;tm.tm_mon=;tm.tm_mday=;intdiff=(int)(mktime(tm)-mktime(tm));cout《《diff/(*)《《endl;
