使用數組生成兩個隨機值

Question

我試圖讓兩只寵物具有兩種不同的情緒狀態。 但是當我運行它時，它們共享相同的狀態，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

我已經將情緒狀態的值存儲在數組中。

我嘗試過使用for循環，以便每個pet都有不同的值，但是我不確定我是否正確執行了操作。

所以我應該為情緒狀態創建兩個不同的數組，還是有更好的做事方法？

這是整個代碼。

Answer 1

那是因為您正在使用EmotionalState數組中的相同值。 在您的方法petInteraction() ，您使用的EmotionalState索引始終為0。 它沒有改變。 因此，根據在數組第0個索引中存儲的任何整數，在for循環中獲取的所有pet最終都會產生情緒。 您需要使用不同的索引來從數組中獲取不同的值。 同樣，根據您的代碼，您使用的索引應該相差3，以使它們隨時具有兩種不同的情感。

編輯

在您的方法中，您有一個for循環，該循環循環兩次。每次創建一只新寵物。 現在，您獲得了寵物的名字之后，便有了一個if-else構造。 不說您的EmotionalState數組在第0個索引中的值為10。 對於第一只寵物，它將進入第三只寵物。 它會打印出危險。 在for循環的第二次運行中，寵物名稱更改，但第0個索引中的值仍為10。因此它將再次打印出現在很危險的信息。 永遠不會輸入前兩個if塊，因為第0個索引中的值始終為10，並且在程序中永不更改。 這就是導致它表現出相同情緒狀態的原因。 您可以做的是，可以在for循環的每次運行中生成一個隨機數，並更新EmotionalState數組的第0個索引，這兩個數字應至少相差3，以便每次運行時都輸入不同的if塊。
