Class 对象数组中的元素存储不当

Question

我正在尝试创建一个程序，该程序是一种根据大五人格测试指定用户心理力量的测验。首先，程序创建一个新的 class 对象和对象的各种属性，例如跟踪结果的分数和五巨头属性的因素。（以及相关的通灵能力。）跟踪。答案是根据提示引导的用户输入做出的。当我运行测试而不是打印五个类别中每个类别的结果时。它只是一遍又一遍地打印最后一个类别。此外，您在任何类别中可以获得的最高分是 25 分，最低分是 5 分。但是，它不是将分数平均分配给每个类别，而是将所有分数都集中到最后一个，最低分 25 分，最高分 125 分。

这里是我的代码：

当代码为运行时，它打印：

您的预知能力非常出色。你的预知能力非常出色。你的预知能力非常出色。你的预知能力非常出色。你的预知能力非常出色。

什么时候打印：

你的千里眼资质微不足道。你的心灵遥控能力是微不足道的。你的超感官知觉能力微不足道。你的心灵感应能力是微不足道的。你的预知能力很差

(注意上面的例子是当我对所有问题都回答 A 时完成的。我知道这是我代码中的逻辑错误。但我的问题是......它是什么，以及如何将分数分配给特定的分数元素而不是集中在一起。

Answer 1

您没有将结果存储在数组中，而是在每次尝试设置值时访问并覆盖静态字段。有关静态字段的更多信息，您可能需要阅读这篇文章：https://docs.oracle.com/javase/tutorial/java/javaOO/classvars.html.

您可以通过将得分、因素和能力声明为 non-static member-variables

来解决此问题

//...
public int score;
public String factor;
public String ability;
//...

并正确初始化您的数组

//...
BigFivePsychokinesisTest[] ResultsArray = new BigFivePsychokinesisTest[5];
for (int i = 0; i < ResultsArray.length; i++) {
    ResultsArray[i] = new BigFivePsychokinesisTest();
}
//...

但是，您可能应该将这些字段移到单独的 class 中，并查看何时以及为何使用 static 关键字（即此处：Java: when to use static methods）。
