java实现猜数字游戏，直到猜对猜跳出

int num = (int)(Math.random()*10);
        System.out.println(num);
        System.out.println("请输入要猜的数字");
        Scanner scan = new Scanner(System.in);
        int input = scan.nextInt();
        while (input != num){
            System.out.println("猜错了");
            input = scan.nextInt();
        }
        System.out.println("猜对了");
