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：
public HandleRequest chuti(HandleRequest handleRequest){ //有乘除法 if(handleRequest.getChengchufa()){ //有余数 if(handleRequest.getShifuyushu()){ //有负数 if(handleRequest.getShifufushu()){ //有余有负 return getchengchumeiyuyoufu(handleRequest); }else{ //有余没负 return getchengchuyouyumeifu(handleRequest); } } //没有余数 else{ if(handleRequest.getShifufushu()){ //没有余数 有负数 return getchengchumeiyuyoufu(handleRequest); }else{ return getchengchumeiyumeifu(handleRequest); } } }//没有乘除 else{ if(handleRequest.getShifufushu()){ return getjiajianyoufu(handleRequest); }else{ return getjiajianmeifu(handleRequest); } } }
HandleRequest.java：
public class HandleRequest implements Serializable { private Boolean chengchufa;//是否有乘除法 private Boolean shifuyushu;//是否有余数 private Boolean shifufushu;//是否有负数 private int questnum=10; //题目数量 private int maxnum=10;//整数的取值范围 private int correctresultnum;//正确题目数量 private List<Questions> qusetions;//题目集合
Questions.java：
public class Questions implements Serializable{ private int id;//题目号 private float fistnum;//第一个数字 private String fuhao;//运算符号 private float secondnum;//第二个数字 private float correctresult; //正确结果 private float inputresult;//输入结果 private int inputyushu; //输入余数 private int yushu;//余数
QuestionService.java：
public HandleRequest chuti(HandleRequest handleRequest){ //有乘除法 if(handleRequest.getChengchufa()){ //有余数 if(handleRequest.getShifuyushu()){ //有负数 if(handleRequest.getShifufushu()){ //有余有负 return getchengchumeiyuyoufu(handleRequest); }else{ //有余没负 return getchengchuyouyumeifu(handleRequest); } } //没有余数 else{ if(handleRequest.getShifufushu()){ //没有余数 有负数 return getchengchumeiyuyoufu(handleRequest); }else{ return getchengchumeiyumeifu(handleRequest); } } }//没有乘除 else{ if(handleRequest.getShifufushu()){ return getjiajianyoufu(handleRequest); }else{ return getjiajianmeifu(handleRequest); } } }
