我的解决方案!

import java.util.HashMap;
import java.util.Map;

public enum MapEnumSample {
    Mustang("One of the fastest cars in the world!"), 
    Mercedes("One of the most beautiful cars in the world!"), 
    Ferrari("Ferrari or Mercedes, which one is the best?");

    private final String description;
    private static Map<String, String> enumMap;

    private MapEnumSample(String description) {
        this.description = description;
    }

    public String getEnumValue() {
        return description;
    }

    public static String getEnumKey(String name) {
        if (enumMap == null) {
            initializeMap();
        }
        return enumMap.get(name);
    }

    private static Map<String, String> initializeMap() {
        enumMap = new HashMap<String, String>();
        for (MapEnumSample access : MapEnumSample.values()) {
            enumMap.put(access.getEnumValue(), access.toString());
        }
        return enumMap;
    }

    public static void main(String[] args) {

        // getting value from Description
        System.out.println(MapEnumSample.getEnumKey("One of the fastest cars in the world!"));

        // getting value from Constant
        System.out.println(MapEnumSample.Mustang.getEnumValue());

        System.out.println(MapEnumSample.getEnumKey("One of the most beautiful cars in the world!"));
        System.out.println(MapEnumSample.Mercedes.getEnumValue());

        // doesnt exist in Enum
        System.out.println("Mustang or Mercedes, which one is the best?");
        System.out.println(MapEnumSample.getEnumKey("Mustang or Mercedes, which one is the best?") == null ? "I don't know!" : "I believe that "
                + MapEnumSample.getEnumKey("Ferrari or Mustang, which one is the best?") + " is the best!.");

        // exists in Enum
        System.out.println("Ferrari or Mercedes, wich one is the best?");
        System.out.println(MapEnumSample.getEnumKey("Ferrari or Mercedes, which one is the best?") == null ? "I don't know!" : "I believe that "
                + MapEnumSample.getEnumKey("Ferrari or Mercedes, which one is the best?") + " is the best!");

    }
}

你可以使用Mode.mode1.name()，但是你通常不需要这样做。

Mode mode =
System.out.println("The mode is "+mode);

据我所知，唯一的办法就是

Mode.mode1.name();

然而，如果你真的需要这样做，你可以这样做:

public enum Modes {
    mode1 ("Mode1"),
    mode2 ("Mode2"),
    mode3 ("Mode3");

    private String name;       

    private Modes(String s) {
        name = s;
    }
}

每个枚举都有一个name()和valueOf(String)方法。前者返回enum的字符串名称，后者给出名称为该字符串的enum值。这就是你要找的吗?

String name = Modes.mode1.name();
Modes mode = Modes.valueOf(name);

Enum本身也有一个静态valueOf(Class, String)，所以你也可以使用:

Modes mode = Enum.valueOf(Modes.class, name);

mode1.name()或String.valueOf(mode1)。恐怕没有比这更好的了

你可以简单地使用:

""+ Modes.mode1
