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。
