用java语言写一个生成100以内加减法算式并且结果也是100以内

的程序，每次运行程序生成10道算式。

import java.util.Random;

public class MathGenerator {
    public static void main(String[] args) {
        Random random = new Random();
        int maxNum = 100;
        int numOfQuestions = 10;
        for (int i = 0; i < numOfQuestions; i++) {
            int num1 = random.nextInt(maxNum) + 1;
            int num2 = random.nextInt(maxNum) + 1;
            int operator = random.nextInt(2); // 0: addition, 1: subtraction
            int result;
            String operatorSymbol;
            if (operator == 0) {
                result = num1 + num2;
                operatorSymbol = "+";
            } else {
                result = num1 - num2;
                operatorSymbol = "-";
            }
            if (result >= 0 && result <= maxNum) {
                System.out.println(num1 + " " + operatorSymbol + " " + num2 + " = " + result);
            } else {
                i--; // regenerate question
            }
        }
    }
}
