Java枚举类型错误 [英] Java Enumerated Types Error

问题描述

所以我有一个基类，我用这个代码块定义一个枚举变量。

 枚举阵营{
 AMITY，ABNIGATION，DAUNTLESS，EURIDITE，CANDOR 
}; 
  

我试图通过使用驱动程序来检查我的子类中的所有内容是否工作。我的子类中的构造函数看起来像这样。

  public Dauntless（String f，String l，int a，int ag，int end，Faction d）{
超级（f，l，a，d）; 
 if（ag> = 0&& ag< = 10）{
 this.agility = ag; 
} else {
 this.agility = 0; 
} 
 if（end> = 0&& end< = 10）{
 this.endurance = end; 
} else {
 this.endurance = 0; 
} 
} 
  

我的驱动程序看起来像这样

  public class Test {
 public static void main（String [] args）{
 Faction this = Faction.DAUNTLESS; 
无耻的乔=新的无畏（约瑟夫，胡珀，20，5，3，这个）; 
无畏Vik =新无畏（维多利亚，病房，19，6，2，这个）; 
无耻的赢家
 winner = joe.battle（vik）; 
 System.out.println（winner）; 
 
 
} 
  

它一直说 Faction this = Faction.DAUNTLESS; 不是一个语句。有人可以帮助我吗？

解决方案

如评论中所述， this 是Java中的关键字，用于以下内容：

  this.faction; 
  

您不能将关键字用作变量名称。只需更改变量名称：

  Faction this_faction = Faction.DAUNTLESS; 
  

然后，当然，您需要更改对变量的引用：

  Dauntless joe = new Dauntless（Joseph，Hooper，20，5，3，this_faction）; 
无敌vik =新无畏（维多利亚，病房，19,6，2，this_faction）; 
  

so I have a base class where I define an enum variable with this block of code.

    enum Faction {
            AMITY, ABNIGATION, DAUNTLESS, EURIDITE, CANDOR
        };

And I'm trying to test to see if everything in my subclass works by using a driver. My constructor in my subclass looks like this.

public Dauntless(String f, String l, int a,  int ag, int end, Faction d) {
        super(f, l, a, d);
        if (ag >= 0 && ag <= 10) {
            this.agility = ag;
        } else {
            this.agility = 0;
        }
        if (end >= 0 && end <= 10) {
            this.endurance = end;
        } else {
            this.endurance = 0;
        }
    }

And my driver looks like this

public class Test {
    public static void main(String[] args) {
        Faction this = Faction.DAUNTLESS;
        Dauntless joe = new Dauntless("Joseph", "Hooper", 20, 5, 3, this);
        Dauntless vik = new Dauntless("Victoria", "Ward", 19, 6, 2, this);
        Dauntless winner;
        winner = joe.battle(vik);
        System.out.println(winner);


}

It keeps saying that Faction this = Faction.DAUNTLESS;is not a statement. Can somebody help me out here?

解决方案

As mentioned in the comments, this is a keyword in Java, used for things like:

this.faction;

You can't use keywords as variable names. Just change the variable name:

Faction this_faction = Faction.DAUNTLESS;

Then, of course, you need to change references to the variable:

Dauntless joe = new Dauntless("Joseph", "Hooper", 20, 5, 3, this_faction);
Dauntless vik = new Dauntless("Victoria", "Ward", 19, 6, 2, this_faction);
