请利用java和mysql知识按照下列要求编写正确代码：测验结束时将向⽤户显⽰反馈屏幕其中包含以下信息：⼀种。a。总问题数b。正确的c。不正确的d。百分⽐百分⽐应保留在步骤1中提到的Score变量中

假设题目答案已经存储在一个数组中，以下是Java和MySQL代码示例：

Java代码：

// 假设变量totalQuestions为总问题数，correctAnswers为正确的问题数，incorrectAnswers为不正确的问题数 int totalQuestions = 10; int[] answers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; int correctAnswers = 7; int incorrectAnswers = totalQuestions - correctAnswers; double score = ((double)correctAnswers / totalQuestions) * 100; // 计算百分比

// 输出反馈屏幕信息 System.out.println("总问题数：" + totalQuestions); System.out.println("正确的问题数：" + correctAnswers); System.out.println("不正确的问题数：" + incorrectAnswers); System.out.println("百分比：" + score + "%");

MySQL代码：

-- 假设表名为quiz_results，包含以下列：id, total_questions, correct_answers, incorrect_answers, score -- 创建表 CREATE TABLE quiz_results ( id INT PRIMARY KEY AUTO_INCREMENT, total_questions INT, correct_answers INT, incorrect_answers INT, score DOUBLE );

-- 插入数据 INSERT INTO quiz_results (total_questions, correct_answers, incorrect_answers, score) VALUES (10, 7, 3, 70.0);

-- 查询数据 SELECT * FROM quiz_results
