用java写个答题系统

好的，下面是一个简单的Java答题系统的代码示例：

import java.util.Scanner;

public class QuizSystem {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        String[][] questions = {
                {"What is the capital of France?", "Paris"},
                {"What is the largest planet in our solar system?", "Jupiter"},
                {"What is the highest mountain in the world?", "Mount Everest"}
        };

        int score = 0;

        for (String[] question : questions) {
            System.out.println(question[0]);
            String answer = scanner.nextLine();

            if (answer.equalsIgnoreCase(question[1])) {
                System.out.println("Correct!");
                score++;
            } else {
                System.out.println("Incorrect. The correct answer is " + question[1]);
            }
        }

        System.out.println("Your final score is " + score + "/" + questions.length);
    }
}

这个答题系统包含了三个问题和对应的答案。程序会依次显示每个问题，等待用户输入答案。如果用户输入的答案与正确答案匹配，则程序会输出"Correct!"并将得分加1；否则输出"Incorrect. The correct answer is xxx"。

最后，程序会计算用户的总分并输出。
