问题描述

我知道这似乎是一种不可原谅的罪,但我有 150个变量,我想创建一个 if function 来执行以下操作:

I know this is going to seem like an unforgiveable sin, but I have 150 variables, and I want to create an if function that does the following:

if(a != 0 && b != 0 && c != 0....) {
  //do this
} else {
  //do this instead
}

然而,当我设置一个if语句条件(即 b!= 1 )时,其他仍然是相同的( a!= 0 c!= 0 ),else函数仍在运行,甚至虽然它应该是最初的 //这个而不是 //这样做(参见上面的代码片段) 。

However, when I set one of the if statement conditions (i.e b!=1), whilst the others are still the same (a!=0, c!=0), the else function is still run, even though it should be the initial //do this instead of the //do this instead (see code snippet above).

我的问题是:

1。这是有原因的吗?不工作,如果有,我该如何解决?

2。有没有更简单的方法可以做到这一点而无需列出所有150个变量!= 0&& != 0 etc ..?

1. Is there a reason why it is not working, and if there is, how do i fix it?
2. Is there a simpler way to do that without having to list all 150 variables !=0 && !=0 etc..?

干杯

推荐答案

当然这样做会更简单:

List<Integer> values = new ArrayList<Integer>();

values.add(val1);
values.add(val2);
// And so forth...

boolean pass = true;

for (Integer v : values) {
    if (v != 0) {
        pass = false;
        // You could log which variable failed here...
    }
}

if (pass) {
    // Do something
} else {
    // Do something else
}
