Java 对数组排序并将结果用于if语句
程序首先要求用户输入两个宠物名。然后，它将打印他们的愤怒程度，如下所示：Java 对数组排序并将结果用于if语句,java,arrays,sorting,Java,Arrays,Sorting,程序首先要求用户输入两个宠物名。然后，它将打印他们的愤怒程度，如下所示： 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!!!. 然后它会问你是否愿意首先照顾愤怒的宠物。我在名为sort（…）的方法中完成了这项工作，这就是我遇到的问题 我希望它执行代码的喂食/歌唱部分，首先在愤怒的
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!!!.

公共类alientpetprogram

公共静态void main（字符串[]args）
{
//为宠物的情绪状态生成1-10之间的随机值
int[]状态=新int[3]；
随机情绪=新随机（）；
对于（int i=0；i您需要将状态与宠物名称相关联。我建议您创建一个带有名称及其情绪状态的类pet
，该类实现了Comparable
接口，以便您可以根据宠物的愤怒状态轻松地对其进行排序
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();
}
}
然后按已执行的操作对阵列进行排序：
Arrays.sort(pets);
现在数组中的第一个对象将是最愤怒的宠物，您可以使用适当的类getter方法轻松提取它的名字。好的，我更改了一些内容，从这里开始，我希望您知道它应该朝哪个方向发展。：）
现在仍然存在错误，您必须修复它们。如果您有两个宠物，为什么要处理3种情绪状态？在创建宠物并为其提供情绪状态后，您不应该再使用情绪状态（java约定的首字母小写）数组
只是一些附加信息：Java是一种面向对象编程
语言，因为您可以将真实对象表示为类（因此可以通过new
创建instances=Object）。这就是为什么应该使用附加类Pet
，因为您可以用它表示真实世界的事物。：）（ofc不仅允许存在于我们世界中的东西，还允许外星人：P）
下面是我迄今为止修改过的代码，正如一开始提到的，你必须修改整个代码，因为有些东西不再兼容了
希望这有帮助
类别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;
}
}
使用String carePet=JOptionPane.showInputDialog（“您想先照顾愤怒的宠物吗？”）；if（carePet.equalsIgnoreCase（“是”）{}else if（carePet.equalsIgnoreCase（“否”）{System.out.println（“+EmotionalState[SortAnger]”）；
我目前使用的格式，因为我不知道如何在我的代码中实现你的建议。现在不可能，因为宠物一创建，感觉部分就会打印出来，你会在之后进行排序。因此，首先用户需要创建宠物，然后你可以询问他是否希望最愤怒的宠物打印feeling语句。Giorashc设计提示让你的生活更轻松，我也建议你，因为现在你的宠物和情感是松散耦合的。你知道我的意思吗？：）我的回答对你有帮助吗？如果你有任何问题，请随时提问！
