采用java编写一个软件，100以内的口算题【软件构造大作业】

采用java编写一个软件，100以内的口算题【软件构造大作业】 看了另一位大佬的帖子，自己搞了搞，比较菜，勿喷

链接在底部。

（1）启动项目后，访问http://localhost:8080/getCalculation，为展示方便，以生成10道计算题为例展示，主页如下：

（2）前端js验证要求运算结果位于[0,100]，且必须全部答完，否则不能提交。

（3）作答提交

（4）提交后得到本次的错题集，并自动计算本次得分和错题数。

（5）错题已经被保存到文件中且不会被覆盖

（6）点击按钮会自动返回练习主页，可以选择继续练习
（7）编写完工具类后的单元测试，显示成功输出。

下面是代码，本人才疏学浅，大佬轻喷：

@Configuration
public class CalculationUtil {

    @Bean
    public Problem getCalculation() {
        List calculationList = new ArrayList<>();
        Problem problem = new Problem();
        Integer[] result = new Integer[10];
        int m = 0, n = 0, value = 0;
        String op = "+";
        Random random = new Random();
        for (int i = 0; i < 10; i++) {
            int o = random.nextInt(2);
            if (o == 0) {
                op = "+";
                do{
                    m = random.nextInt(101);
                    n = random.nextInt(101);
                    value = m + n;
                }while (value > 100);
            } else {
                op = "-";
                do {
                    m = random.nextInt(101);
                    n = random.nextInt(101);
                    value = m - n;
                }while (value < 0);
