对数组进行排序并将结果用于if语句

Question

该程序首先要求用户输入两个宠物名称。然后它会打印他们的愤怒程度如下：

Oh cool, Poodle is a very unique name! 
Poodle is feeling tetchy! 
Oh cool, Ollie is a very unique name! 
Ollie is DANGEROUS RIGHT NOW!!!. 

然后它会问你是否想先照顾愤怒的宠物。我已经在称为sort（...）的方法中完成了这个工作，而这正是我卡住的地方。

我希望它执行代码的喂食/唱歌部分，它发生在愤怒宠物的petInteraction（...）中，如果用户在被要求时输入Yes，如果没有，则运行代码照常。

Answer 1

您需要的状态与宠物相关name.I'll建议你创建一个类Pet的名称和它的情绪状态，它实现Comparable接口，所以你可以根据他们的愤怒状态轻松地对宠物进行排序。

public class Pet implements Comparable<Pet> { 
    private String name; 
    private int state; 

    // Add required basic methods here 

    int compareTo(Pet pet) { 
     return state - pet.getState(); 
    } 
} 

然后定义数组：

Pet pets[] = // Initialize with Pet objects 

数组然后进行排序，你已经做了：

Arrays.sort(pets); 

现在数组中的第一个对象将是angriest宠物和你可以用适当的类getter方法轻松地提取他的名字。

Answer 2

好吧我改变了一些东西，从这里开始，我希望你知道它应该采取哪个方向。 :) 现在仍然存在错误，您必须修复它们。如果你有两只宠物，你为什么在3种情绪状态下工作？在创建宠物并给予他们情绪状态后，你不应该再使用emotionState（java convention的第一个字母小写）数组。

只是一些附加信息：Java是Object-Oriented Programming语言，因为您可以将实际对象表示为类（因此可通过new创建实例=对象）。这就是为什么应该使用额外的类Pet，因为你代表了一个真实的世界。 :)（ofc不仅仅是我们世界中真正存在的东西，外星人也被允许：P）

以下是我到目前为止改变的代码，正如开始时提到的，您必须修改整个代码，因为有些东西不是兼容了。

希望这会有所帮助！

类Pet：

public class Pet implements Comparable<Pet> { 
private String name; 
private int state; 

/** 
* @return Returns the state. 
*/ 
public int getState() 
{ 
    return state; 
} 

/** 
* @param state The state to set. 
*/ 
public void setState(int state) 
{ 
    this.state = state; 
} 

public int compareTo(Pet pet) { 
    return state - pet.getState(); 
} 

/** 
* @return Returns the name. 
*/ 
public String getName() 
{ 
    return name; 
} 

/** 
* @param name The name to set. 
*/ 
public void setName(String name) 
{ 
    this.name = name; 
} 
} 

类alientpetprogram：

    } 

    //fill the array already with 2 pets
