3.10（游戲：加法測(cè)試）程序清單3-3隨機(jī)產(chǎn)生一個(gè)減法問(wèn)題。修改這個(gè)程序，隨機(jī)產(chǎn)生一個(gè)計(jì)算兩個(gè)小于100的整數(shù)的加法問(wèn)題

參考：程序清單3-3

import java.util.Scanner;public class QingDan {public static void main(String[] args) {// 1. Generate two random single-digit integersint number1 = (int)(Math.random() * 10);int number2 = (int)(Math.random() * 10);// 2. If number1 < number2, swap number1 with number2if(number1 < number2){int temp = number1;number1 = number2;number2 = temp;}// 3. Prompt the student to answer "What is number1-number2?"System.out.println("What is "+number1+" - " + number2 + "? ");Scanner input = new Scanner(System.in);int answer = input.nextInt();// 4. Grade the answer and display the resultif(number1 - number2 == answer)System.out.println("You are correct!");else{System.out.println("Your answer is wrong.");System.out.println(number1 + " - " + number2+" should be "+(number1-number2));}} }
