我在Java中组织这些if语句时遇到了很多麻烦

I have to do a recommend-a-laptop project for school, and I want to keep it as concise as possible by using very long if statements with multiple conditions. I have many of these, but here's one of them:

我必须为学校做推荐的笔记本电脑项目,我希望通过使用具有多个条件的非常长的if语句来尽可能简洁。我有很多这些,但这里有一个:

if 
      ((questionArray [0].equals ("A") && (questionArray [1].equals ("A") || ("B") || ("C") || ("D")) && questionArray [2].equals ("A") && questionArray [3].equals ("A") && questionArray [4].equals ("A") || ("B") || ("C") || ("D")) 
{


System.out.println("ASUS Laptop E200HA-UB02-GD 11.6 inch");

}

I am constantly getting, Error: '(' expected and I can't seem to figure it out. Please help!

我经常得到,错误:'('预计,我似乎无法弄清楚。请帮忙!

After || , you need to write questionArray [4].equals("B")...

在||之后,你需要写questionArray [4] .equals(“B”)......

The complete code

完整的代码

 if ((questionArray[0].equals("A")) && (questionArray[1].equals("A"))
                || (questionArray[1].equals("B")) || (questionArray[1].equals("C"))
                || (questionArray[1].equals("D")) && (questionArray[2].equals("A"))
                && (questionArray[3].equals("A")) && (questionArray[4].equals("A"))
                || (questionArray[4].equals("B")) || (questionArray[4].equals("C"))
                || (questionArray.equals("D"))) 
  {

      System.out.println("ASUS Laptop E200HA-UB02-GD 11.6 inch");
   }

The error gone now but I'm not sure whether this code wii work since I never tried mixing the || operator with the && operator.

错误现在消失但我不确定这段代码是否有效,因为我从未尝试过混合||运算符与&&运算符。
