程序代码：

Random random = new Random();
        int randomNum = random.nextInt(10)+1;
        Scanner scanner = new Scanner(System.in);
        int times=1;
        while(times<=3){
            int cur=scanner.nextInt();
            if(cur!=randomNum){
                System.out.println("wrong");
            }else{
                System.out.println("yes");
                break;
            }
            times++;
        }
        scanner.close();

要有计数器思想，加count
