我试图让这两只宠物有两种不同的情绪状态。但是当我运行它时，它们共享相同的状态，如下所示：
Oh cool, asda is a very unique name!
asda is DANGEROUS RIGHT NOW!!!.
Oh cool, polo is a very unique name!
polo is DANGEROUS RIGHT NOW!!!.
asda's irrtability level is 4
asda's thirst level is 8
asda's hunger level is 5
polo's irrtability level is 4
polo's thirst level is 8
polo's hunger level is 5
我已将情绪状态的值存储在数组中。
我尝试过使用for循环，以便每个宠物都有不同的值，但我不确定我是否正确使用它。
那么我应该为情绪状态创建两个不同的数组，还是有更好的做事方式？
这是整个代码。

答案 0 :(得分：1)
这是因为您使用的是EmotionalState数组中的相同值。在方法petInteraction()中，您使用的EmotionalState索引始终为0。它没有改变。因此，在for循环中获取的所有宠物将根据存储在数组的第0个索引中的任何整数来获得情绪。您需要使用不同的索引从数组中获取不同的值。此外，根据您的代码，您使用的索引应该有3的差异，以使他们在任何时候都有两种不同的情绪。
修改
在你的方法中，你有一个for循环，它循环两次。每个新宠物的时间。现在，在获得宠物的名称后，您将拥有一个if-else结构。不，说你的EmotionalState数组在第0个索引中保持值10。对于第一只宠物，它将进入第三只。它将打印出危险的信息。在for循环的第二次运行中，pet名称更改，但第0个索引中的值仍为10.因此，它将再次打印出它现在是危险的。永远不会输入前两个if块，因为第0个索引中的值始终为10，并且程序中永远不会更改。这就是导致它打印出相同情绪状态的原因。你可以做的是你可以在for循环的每次运行中生成一个随机数并更新EmotionalState数组的第0个索引，这两个数字应该至少有3个差值，这样每次运行时它会输入一个不同的if块。
