java题库管理程序设计代码

好的，以下是一个简单的Java题库管理程序设计代码，仅供参考：

Question.java：

public class Question {
    private String type;  // 题型，包括单选题、多选题和判断题
    private String stem;  // 题干
    private String optionA;
    private String optionB;
    private String optionC;
    private String optionD;
    private String answer;  // 答案，单选题和判断题只有一个正确答案，多选题可能有多个答案

    public Question(String type, String stem, String optionA, String optionB, String optionC, String optionD, String answer) {
        this.type = type;
        this.stem = stem;
        this.optionA = optionA;
        this.optionB = optionB;
        this.optionC = optionC;
        this.optionD = optionD;
        this.answer = answer;
    }

    // getter和setter方法
    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getStem() {
        return stem;
    }

    public void setStem(String stem) {
        this.stem = stem;
    }

    public String getOptionA() {
        return optionA;
    }

    public void setOptionA(String optionA) {
        this.optionA = optionA;
    }

    public String getOptionB() {
        return optionB;
    }

    public void setOptionB(String optionB) {
        this.optionB = optionB;
    }

    public String getOptionC() {
        return optionC;
    }

    public void setOptionC(String optionC) {
        this.optionC = optionC;
    }

    public String getOptionD() {
        return optionD;
    }

    public void setOptionD(String optionD) {
        this.optionD = optionD;
    }

    public String getAnswer() {
        return answer;
    }

    public void setAnswer(String answer) {
        this.answer = answer;
    }
}

QuestionManager.java：

import java.io.*;
import java.util.ArrayList;
import java.util.List;

public class QuestionManager {
    private List<Question> questionList;

    public QuestionManager() {
        questionList = new ArrayList<>();
    }

    // 增加试题
    public void addQuestion(Question question) {
        questionList.add(question);
    }

    // 删除试题
    public void deleteQuestion(Question question) {
        questionList.remove(question);
    }

    // 修改试题
    public void updateQuestion(Question question) {
        for (int i = 0; i < questionList.size(); i++) {
            if (questionList.get(i).getStem().equals(question.getStem())) {
                questionList.set(i, question);
                break;
            }
        }
    }

    // 查询试题
    public List<Question> getQuestion(String questionType) {
        List<Question> result = new ArrayList<>();
        for (Question question : questionList) {
            if (question.getType().equals(questionType)) {
                result.add(question);
            }
        }
        return result;
    }

    // 导入试题
    public void importQuestions(String filePath) {
        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                String[] fields = line.split(",");
                if (fields.length != 8) {
                    throw new IllegalArgumentException("Invalid question format: " + line);
                }
                Question question = new Question(fields[0], fields[1], fields[2], fields[3], fields[4], fields[5], fields[6]);
                addQuestion(question);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    // 导出试题
    public void exportQuestions(String filePath) {
        try (PrintWriter writer = new PrintWriter(new FileWriter(filePath))) {
            for (Question question : questionList) {
                writer.println(question.getType() + "," + question.getStem() + "," + question.getOptionA() + ","
                        + question.getOptionB() + "," + question.getOptionC() + "," + question.getOptionD() + ","
                        + question.getAnswer());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这里只是一个简单的实现，具体的代码实现还需要根据实际情况进行调整和完善。
