使用数组产生两个随机值

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 

我已经将情绪状态值存储在数组中。

我试过使用for循环，以便每个宠物会有不同的值，但我不知道如果我做得正确。

所以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？

这里是整个代码。

import javax.swing.*; 
import java.util.Random; 
public class alientpetprogram 
{ 

public static void main(String[] args) 
{ 

    int[] EmotionalState = new int [3]; 
    Random emotion = new Random(); 
    for(int i = 0; i <= 2; i++) 
    { 
    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); 
} //ENDS main 

    public static String[] petInteraction(int[] EmotionalState, String [] petName) //Use this further on in petEmotion() 
    { 
     for(int i = 0; i < 2; i++) 
     { 
      petName[i] = JOptionPane.showInputDialog("What is your pet called?"); 
      System.out.println("Oh cool, " + petName[i] + " is a very unique name!"); 


      if (EmotionalState[0] == 1 || EmotionalState[0] == 2 || EmotionalState[0] == 3) 
      { 
       System.out.println(petName[i] + " is feeling Calm."); 
      } 
      else if (EmotionalState[0] == 4 || EmotionalState[0] == 5 || EmotionalState[0] == 6) 
      { 
       System.out.println(petName[i] + " is feeling tetchy!"); 
      } 
      else if (EmotionalState[0] == 7 || EmotionalState[0] == 8 || EmotionalState[0] == 9 || EmotionalState[0] == 10) 
      { 
       System.out.println(petName[i] + " is DANGEROUS RIGHT NOW!!!."); 
      } 

     } 
     return petName; 
    } //ENDS petInteraction 

       public static void petEmotion(int[] EmotionalState, String [] petName) //This method changes the emotional states of the pet. 
       { 
         String[] petsName = petInteraction(EmotionalState, petName);

这是因为您正在使用EmotionalState数组中的相同值。在您的方法petInteraction()中，您正在使用的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结束感情。您需要使用不同的索引来从数组中获取不同的值。此外，根据你的代码，你使用的指数应该有3的差异，让他们在任何时候都有两种不同的情绪。

在你的方法，你有一个for循环，其循环2个times.Each时间为一个新的宠物。现在获得宠物的名字后，你有一个if-else结构。不要说你的EmotionalState数组在第0个索引中保持值10。对于第一只宠物来说，它会进入第三只宠物。它会打印出它很危险。在for循环的第二次运行中，宠物名称会更改，但第0个索引中的值仍然为10.因此，它会再次打印出现在是危险的。前两个if块永远不会进入，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。那是什么导致它打印出同样的情绪状态。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，这两个数字应该有至少3的差值，这样每次运行它都会进入一个不同的if块。
