java怎么自定义问卷表结构

在Java中，可以使用对象来表示问卷表结构。首先，创建一个Question类来表示问题，该类可以包含问题的内容、选项列表、答案等属性。然后，创建一个Questionnaire类来表示问卷表，该类包含问题列表、问卷名称、创建时间等属性。

下面是一个示例代码：

import java.util.ArrayList; import java.util.Date; import java.util.List;  public class Question {     private String content;     private List<String> options;     private String answer;          public Question(String content, List<String> options, String answer) {         this.content = content;         this.options = options;         this.answer = answer;     }          // getters and setters          public String getContent() {         return content;     }      public void setContent(String content) {         this.content = content;     }      public List<String> getOptions() {         return options;     }      public void setOptions(List<String> options) {         this.options = options;     }      public String getAnswer() {         return answer;     }      public void setAnswer(String answer) {         this.answer = answer;     } }  public class Questionnaire {     private String name;     private Date createDate;     private List<Question> questions;          public Questionnaire(String name) {         this.name = name;         this.createDate = new Date();         this.questions = new ArrayList<>();     }          // getters and setters          public String getName() {         return name;     }      public void setName(String name) {         this.name = name;     }      public Date getCreateDate() {         return createDate;     }      public void setCreateDate(Date createDate) {         this.createDate = createDate;     }      public List<Question> getQuestions() {         return questions;     }      public void setQuestions(List<Question> questions) {         this.questions = questions;     } }  public class Main {     public static void main(String[] args) {         // 创建问卷表         Questionnaire questionnaire = new Questionnaire("Java基础知识调查问卷");                  // 创建问题         Question question1 = new Question("Java中的基本数据类型有哪些？",                  List.of("int", "double", "boolean", "char"), "int");         Question question2 = new Question("Java中的循环语句有哪些？",                  List.of("for", "while", "do-while", "if-else"), "for");                  // 添加问题到问卷表         questionnaire.getQuestions().add(question1);         questionnaire.getQuestions().add(question2);                  // 输出问卷表内容         System.out.println("问卷名称：" + questionnaire.getName());         System.out.println("创建时间：" + questionnaire.getCreateDate());                  for (Question question : questionnaire.getQuestions()) {             System.out.println("问题：" + question.getContent());             System.out.println("选项：" + question.getOptions());             System.out.println("答案：" + question.getAnswer());             System.out.println();         }     } } 

以上代码创建了一个问卷表，并包含了两个问题。可以根据实际需求，添加更多的问题和选项。
