2. 編寫程序，使它產(chǎn)生10個隨機數(shù)加法問題，加數(shù)是1到15之間的整數(shù)，讓用戶輸入答案后驗證用戶的答案是否正確，每答對一題得10分，統(tǒng)計并最后輸出用戶得分（原題）package pro2;import java.util.Random;import java.util.*;public class Dome_4 { public static void main(String[] args) { // TODO Auto-generated method stub int grade = 0; Scanner input = new Scanner(System.in); System.out.println("請輸入答案"); int s = input.nextInt(); Random r = new Random(); int a = r.nextInt(15); Random r1 = new Random(); int arr[] = new int[10]; for (int i = 0; i < arr.length; i++) { arr[i] = r1.nextInt(15); if (s = arr[i] + a) { System.out.println("恭喜你做對了" + grade + 10); } } }}
