微信公开课小程序热门讨论「求JAVA小程序.」最新回复-1、编写一个Java程序读取Windows目录下的win.ini文件,并打印输出其内容。答：自己看看下面的链接应该是可以学会的。http://hi.baidu.com/jackie_feng/blog/item/66958cdd34fc62305882dd10.html2.用字符流读写文件，要求如下:a.将自己的简单个人简介写入aa.txt;b.从aa.txt中读取并打印。答：这个自己写吧，无非就是读流写流的过程。3.从命令行接收10个参数，从小到大打印出来，并打印出他们的和以及平均数。答：publicstaticvoidmain(String[]args){int[]list=newint[args.length];intsum=0;doubleavg=0;for(inti=0;ilist.length;i++){list[i]=Integer.parseInt(args[i]);sum+=list[i];}Arrays.sort(list);for(inti=0;ilist.length;i++){System.out.println(list[i]);}System.out.println(平均数：+avg);System.out.println(和：+sum)}4.定义一个MyString类，写以下四个方法：a、booleanisNumber(Strings):判断参数是否是数字，返回布尔值。b、booleanisLetter(Strings):判断参数是否是字母，返回布尔值。c、booleanisUpper(Strings):判断参数是否是大写字母，返回布尔值。d、booleanisLower(Strings):判断参数是否是小写字母，返回布尔值。答：只写方法代码了。booleanisNumber(Strings){returns.matches(\\d+);}booleanisLetter(Strings){returns.matches([azAZ]);}booleanisUpper(Strings){returns.equals(s.toUpperCase());}booleanisLower(Strings){returns.equals(s.toLowerCase());}自己调试下，可能有些地方不太对。5.定义一个MyMath类，写一个用于计算a的b次方的方法，a和b均为参数。答：只写方法代码了doublepow(doublea,doubleb){returnMath.pow(a,b);}6.写一个test类,写以下方法:a、用构造方法初始化两个参数。b、求两者的平均值。c、求两者的最大值。d、求两者的最不值。e、求两者的和差积商。答：publicclassTest{//命名规范，类名要大写privateinta;privateintb;publicTest(){this.a=10;this.b=8;}//平均数publicdoubleavg(){return(a+b)/2;}//最大值publicintmax(){returnMath.max(a,b);}//最小值publicintmin(){returnMath.min(a,b);}//求两者的和差积商。//这4个方法自己写吧}这些题目很像企业的手写代码笔试题目啊！使用这些API的功能可是基本功哦，不要投机取巧，还是自己再写一遍，把印象放入脑中，下次再遇到相同的问题后才能迎刃而解啊！O(∩_∩)O！

printf(Fuckme);追问sha b//?追答少年，默认的c没有图形库函数，你再怎么写也是枯燥的控制面板，要表白，怎么也写个有图的对吧。比如说用Matlab的plot画一个爱心什么的之类的。如果你硬要用c的话，我建议你可以去参考一下，国际乱码大赛的代码，就是要你在代码格式上做文章。如果都不想看的话，你就写fuckme吧，简单直接，基友什么的最喜欢了已赞过已踩过评论收起月霜白露2014-03-15月霜白露采纳数：34获赞数：32LV5擅长：C/C++散文向TA提问私信TA展开全部#includestdio.hintmain(){printf(******** );printf(**** );printf(***** );printf(** );printf(** );printf(** );printf(** );printf(** );printf(** );printf(** );printf(** );printf(** );return0;} 更多有关「求一个 表白的小程序c代码」的疑问请扫码关注微信公开课+小程序！
