Answer 1

我建议将Random方法分配给变量，然后根据该变量执行IF语句。

例如：

                Random rand = new Random();

                int randomNumber = rand.nextInt(10) 

                if randomNumber == 9 {
                //Do this

                }
                else {

               }

10是范围的顶部，因此它将选择0-9之间的任意随机数。

希望这有帮助！
