我正在尝试创建一个程序，该程序是一个测验，根据大五人格测试来指定用户的心灵力量。首先，程序创建一个新的类对象和该对象的各种属性，例如用于跟踪结果的分数和大五属性的因素。(以及相关的心灵能力。)以保持跟踪。答案是根据提示引导的用户输入得出的。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到每个类别，而是将其全部集中到最后一个类别，最低分 25 分，最高分 125 分。
为了澄清，这是我的代码:

当代码运行时，它会打印:
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。 你的预知能力非常出色。
什么时候应该打印:
你的千里眼能力微不足道。 你的心灵传动能力微不足道。 你的额外感官知觉能力微不足道。 你的心灵感应能力微不足道。 你的预知能力微不足道。
(请注意，当我对所有问题都回答 A 时，上面的示例就完成了。 我知道这是我的代码中的逻辑错误。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，而不是集中到一个。
最佳答案
您不会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 .
您可以通过将分数、因子和能力声明为非静态成员变量来解决此问题
//...
public int score;
public String factor;
public String ability;
//...
并正确初始化你的数组
//...
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至单独的类中，并检查何时以及为何使用 static 关键字(即此处: Java: when to use static methods )。
