本文链接：https://blog.youkuaiyun.com/qinghua9/article/details/1650998

本文介绍了一个简单的考试系统中使用的三个核心实体类：AnswerSheet、Paper 和 Question 的 Java 实现。AnswerSheet 类用于存储考生的答案；Paper 类表示试卷，包含一系列问题；Question 类定义了问题的基本属性，如题目ID、描述、选项及正确答案。

package jiangqh.exam.entity;

import java.util.HashMap;
import java.util.Map;

public class AnswerSheet {
private Map<String, String> answers = new HashMap<String,String >();

public Map<String, String> getAnswers() {
return answers;
}

public void setAnswers(Map<String, String> answers) {
this.answers = answers;
}

}

package jiangqh.exam.entity;

import java.util.*;

public class Paper {
private Map<String ,Question >questions =new HashMap<String, Question>();

public Map<String, Question> getQuestions() {
return questions;
}

public void setQuestions(Map<String, Question> questions) {
this.questions = questions;
}

}

package jiangqh.exam.entity;

import java.util.ArrayList;
import java.util.List;

public class Question {
private String qid;
private String desc;

private List<String> options = new ArrayList<String>();
private String rightAnswer;
public String getRightAnswer() {
  return rightAnswer;
}
public void setRightAnswer(String rightAnswer) {
  this.rightAnswer = rightAnswer;
}
public String getDesc() {
  return desc;
}
public List<String> getOptions() {
  return options;
}
public String getQid() {
  return qid;
}
public void setDesc(String desc) {
  this.desc = desc;
}
public void setOptions(List<String> options) {
  this.options = options;
}
public void setQid(String qid) {
  this.qid = qid;
}

}
