对于我的程序，我有大量的公共静态 int，它主要是一个可读性的东西，所以我可以做一些事情，比如SkillsArray[Archery] = 25一眼就能看到“射箭技能”的值/级别/等级为 25，而不是试图弄清楚应该是什么SkillsArray[7] = 25意思。

它基本上是命名要在关系数据库结构中使用的唯一 ID，但如果我想打印这些名称，我会构建一个函数，该函数接受一个 int 参数，该参数读取一个巨大的 if/else 树以吐出一个名为“射箭”或“烹饪”之类的。

我想用简单的东西替换所有这些功能

String printStaticName() {
    return this.getClass().getName();
}

它可以读取附加到它的原语并获得它的名称，但 Eclipse 告诉我我不能对原语类型执行这些操作。想法？

我目前如何使用我拥有的系统的一个例子。

//races
public static final int Chosen = 0;
public static final int Native = 1;
public static final int High_Elf = 2;
public static final int Wood_Elf = 3;
public static final int Gremlin = 4;
public static final int Goblin = 5;
public static final int Hobgoblin = 6;
    ....

String getRaceNameString(int r){
    String temp = "No Race Set";
    if (r == Chosen){temp = "Chosen";};
    if (r == Native){temp = "Native";};
    if (r == High_Elf){temp = "High Elf";};
    if (r == Wood_Elf){temp = "Wood Elf";};
    if (r == Gremlin){temp = "Gremlin";};
    if (r == Goblin){temp = "Goblin";};
    if (r == Hobgoblin){temp = "Hobgoblin";};
    return temp;
}//close getRaceNameString

int getRaceIDFromString(String r){
    int result = 0;
    if (r == "Chosen"){result = Chosen;};
    if (r == "Native"){result = Native;};
    if (r == "High Elf"){result = High_Elf;};
    if (r == "Wood Elf"){result = Wood_Elf;};
    if (r == "Gremlin"){result = Gremlin;};
    if (r == "Goblin"){result = Goblin;};

    return result;
}//close getraceIDFromString()

改用枚举（前提是您的技能是固定的）：

public enum Skill
{
    ARCHERY,
    ETC
}

为了构建技能“阵列”，请使用EnumMap. 例如，您可以在枚举中执行以下操作：

public enum Skill
{
    ARCHERY,
    ETC;

    public static Map<Skill, Integer> newSkillMap()
    {
        final Map<Skill, Integer> ret = new EnumMap(Skill.class);
        for (final Skill skill: values())
            ret.put(skill, 0);
        return ret;
    }
}

用法：

final Map<Skill, Integer> skillMap = Skill.newSkillMap();
map.get(Skill.ARCHERY); // skill for archery
map.put(Skill.ARCHERY, 30); // change value

您甚至可以改进您的枚举，以获得默认值等；枚举可以在 Java中做很多事情。样本：

public enum Skill
{
    ARCHERY(10, "archery"),
    ETC(0, "etc");

    private final int defaultValue;
    private final String description;

    Skill(final int defaultValue, final String description)
    {
        this.defaultValue = defaultValue;
        this.description = description;
    }

    public static Map<Skill, Integer> newSkillMap()
    {
        final Map<Skill, Integer> ret = new EnumMap(Skill.class);
        for (final Skill skill: values())
            ret.put(skill, skill.defaultValue);
        return ret;
    }

    @Override
    public String toString()
    {
        return description;
    }
}

您可以将枚举用于您的目的：

public enum Skill {
  SWORD(0, "Sword"),
  ARCHERY(1, "Archery")
  ;

  public final String name;
  public final int index;

  Skill(int index, String name) {
    this.name = name;
    this.index = index;
  }
}

skillsArray[ARCHERY.index] = 25;
System.out.println(ARCHERY.name+" is +"skillsArchery[ARCHERY.index]);

请注意，ARCHERY.ordinal()如果您更喜欢分配给您的enum值的内置索引，则可以使用。这将更安全但不太灵活（因为它将取决于枚举声明中强加的位置）。
