以上用来生成50道100以内的加减法算式习题,同时也要求和或差也必须是100以内,并输出到控制台,请补全一下

您已经给出了大部分代码,只需要补充循环中判断和或差是否在100以内以及最后输出的部分。以下是完整代码:
```java
import java.util.Random;
public class MathQuizGenerator {
public static void main(String[] args) {
short left = 0, right = 0, result = 0;
char op = '+';
Random random = new Random();
for (int i = 0; i < 50; i++) {
left = (short) random.nextInt(101);
short operatorValue = (short) random.nextInt(2); // 随机选择加法或减法
switch (operatorValue) {
case 0: // 加法
do {
right = (short) random.nextInt(101);
result = (short) (left + right);
} while (result < 0 || result > 100); // 确保结果在100以内
break;
case 1: // 减法
do {
right = (short) random.nextInt(101);
result = (short) (left - right);
} while (left - right < 0 || result > 100); // 确保差值不超过100且左数大于右数
op = '-';
break;
}
System.out.printf("%d.\t%d %c %d = %d\n", i + 1, left, op, right, result);
}
}
}
```
这个程序会生成50道100以内的加减法算式并打印出来,每个算式前有相应的序号。
