这次实验是四则运算系列的最后一次实验，实验的要求是：做成安卓APP版或者网页版，我们组做的是网页版，实验内容如下：
完成本次实验所使用的软件：MyEclipse（主要是学习java时课外所学习的知识）和tomcat（作为服务器，上传实验程序）
主要代码：
QusetionAction.java：
1 public HandleRequest chuti(HandleRequest handleRequest){ 2 3 //有乘除法 4 if(handleRequest.getChengchufa()){ 5 //有余数 6 if(handleRequest.getShifuyushu()){ 7 //有负数 8 if(handleRequest.getShifufushu()){ 9 //有余有负 10 return getchengchumeiyuyoufu(handleRequest); 11 }else{ 12 //有余没负 13 return getchengchuyouyumeifu(handleRequest); 14 } 15 16 } 17 //没有余数 18 else{ 19 20 if(handleRequest.getShifufushu()){ 21 //没有余数 有负数 22 return getchengchumeiyuyoufu(handleRequest); 23 }else{ 24 return getchengchumeiyumeifu(handleRequest); 25 } 26 } 27 28 }//没有乘除 29 else{ 30 if(handleRequest.getShifufushu()){ 31 return getjiajianyoufu(handleRequest); 32 }else{ 33 return getjiajianmeifu(handleRequest); 34 } 35 } 36 37 }
HandleRequest.java：
1 public class HandleRequest implements Serializable { 2 private Boolean chengchufa;//是否有乘除法 3 private Boolean shifuyushu;//是否有余数 4 private Boolean shifufushu;//是否有负数 5 private int questnum=10; //题目数量 6 private int maxnum=10;//整数的取值范围 7 8 private int correctresultnum;//正确题目数量 9 private List<Questions> qusetions;//题目集合
Questions.java：
1 public class Questions implements Serializable{ 2 private int id;//题目号 3 private float fistnum;//第一个数字 4 private String fuhao;//运算符号 5 private float secondnum;//第二个数字 6 private float correctresult; //正确结果 7 private float inputresult;//输入结果 8 private int inputyushu; //输入余数 9 10 private int yushu;//余数 11
QuestionService.java：
