用java6. 编写一个四则运算测试程序，随机产生10道四则运算题目，并将题目在屏幕上显示，等待用户回答，统计得分，并输出最后得分，例如：“您做了10道题，其中正确X道，错误X道，最后得分：XX”。

好的，我可以回答这个问题。以下是一个用Java 6编写的四则运算测试程序的示例代码：

import java.util.Random;
import java.util.Scanner;

public class ArithmeticQuiz {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Random random = new Random();
        int correctCount = 0;
        int wrongCount = 0;
        int totalScore = 0;

        for (int i = 1; i <= 10; i++) {
            int num1 = random.nextInt(100);
            int num2 = random.nextInt(100);
            int operator = random.nextInt(4);
            int answer;
            String operatorSymbol;

            switch (operator) {
                case 0:
                    answer = num1 + num2;
                    operatorSymbol = "+";
                    break;
                case 1:
                    answer = num1 - num2;
                    operatorSymbol = "-";
                    break;
                case 2:
                    answer = num1 * num2;
                    operatorSymbol = "*";
                    break;
                case 3:
                    answer = num1 / num2;
                    operatorSymbol = "/";
                    break;
                default:
                    answer = 0;
                    operatorSymbol = "";
                    break;
            }

            System.out.print("Question " + i + ": " + num1 + " " + operatorSymbol + " " + num2 + " = ");
            int userAnswer = scanner.nextInt();

            if (userAnswer == answer) {
                System.out.println("Correct!");
                correctCount++;
                totalScore += 10;
            } else {
                System.out.println("Wrong! The correct answer is " + answer);
                wrongCount++;
            }
        }

        System.out.println("You answered " + correctCount + " questions correctly and " + wrongCount + " questions incorrectly.");
        System.out.println("Your final score is " + totalScore);
    }
}

希望这个示例代码能够帮助你。
