在Java中，可以使用對象來表示問卷表結(jié)構(gòu)。首先，創(chuàng)建一個Question類來表示問題，該類可以包含問題的內(nèi)容、選項列表、答案等屬性。然后，創(chuàng)建一個Questionnaire類來表示問卷表，該類包含問題列表、問卷名稱、創(chuàng)建時間等屬性。

下面是一個示例代碼：

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) {
        // 創(chuàng)建問卷表
        Questionnaire questionnaire = new Questionnaire("Java基礎(chǔ)知識調(diào)查問卷");
        
        // 創(chuàng)建問題
        Question question1 = new Question("Java中的基本數(shù)據(jù)類型有哪些？", 
                List.of("int", "double", "boolean", "char"), "int");
        Question question2 = new Question("Java中的循環(huán)語句有哪些？", 
                List.of("for", "while", "do-while", "if-else"), "for");
        
        // 添加問題到問卷表
        questionnaire.getQuestions().add(question1);
        questionnaire.getQuestions().add(question2);
        
        // 輸出問卷表內(nèi)容
        System.out.println("問卷名稱：" + questionnaire.getName());
        System.out.println("創(chuàng)建時間：" + questionnaire.getCreateDate());
        
        for (Question question : questionnaire.getQuestions()) {
            System.out.println("問題：" + question.getContent());
            System.out.println("選項：" + question.getOptions());
            System.out.println("答案：" + question.getAnswer());
            System.out.println();
        }
    }
}

以上代碼創(chuàng)建了一個問卷表，并包含了兩個問題?？梢愿鶕?jù)實際需求，添加更多的問題和選項。
