java - 使用数组生成两个随机值

Question

我试图让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执行。

那么我应该为情绪状态创建两个不同的数组，还是有更好的方法？

这是完整的代码。

    int hungerLVL = emotion.nextInt(10) + 1;
    EmotionalState[0] = hungerLVL;

    int thirstLVL = emotion.nextInt(10) + 1;
    EmotionalState[1] = thirstLVL;

    int irritabilityLVL = emotion.nextInt(10) + 1;
    EmotionalState[2] = irritabilityLVL;
    }

    String [] petName = new String [2];
    petEmotion(EmotionalState, petName);

    System.exit(0);

这是因为您使用的是 EmotionalState 数组中的相同值。在您的方法 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最终都会根据数组第 0 个索引中存储的任何整数获得情感。您需要使用不同的索引从数组中获取不同的值。另外，根据您的代码，您使用的索引应相差 3，以使它们随时有两种不同的情绪。

在你的方法中，你有一个 for 循环，它循环两次。每次都是一个新宠物。现在，在获得宠物的名字后，您就有了一个 if-else 结构。不说您的 EmotionalState 数组在第 0 个索引中保存值 10。对于第一个宠物，它将进入第三个if。它会打印出这是危险的。在 for 循环的第二次运行中，宠物名称发生了变化，但第 0 个索引中的值仍然是 10。因此它会再次打印现在很危险。前两个 if block 永远不会输入，因为第 0 个索引中的值始终为 10 并且在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。您可以做的是，您可以在 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相差 3，以便每次运行都会进入不同的 if block 。
