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);

package com.common.test;

public  enum Days {


    monday(1,"Monday"),tuesday(2,"Tuesday"),wednesday(3,"Wednesday"),
    thrusday(4,"Thrusday"),friday(5,"Friday"),saturday(6,"Saturday"),sunday(7,"Sunday");

    private int id;
    private String desc;


    Days(int id,String desc){
        this.id=id;
        this.desc=desc;
    }

    public static String getDay(int id){

        for (Days day : Days.values()) {
            if (day.getId() == id) {
                return day.getDesc();
            }
        }
        return null;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }



};

Enum是一个有点特殊的类。枚举可以存储额外的字段，实现方法等。例如

public enum Modes {
    mode1('a'),
    mode2('b'),
    mode3('c'),
    ;
    char c;

    private Modes(char c) {
        this.c = c;
    }
    public char character() {
        return c;
    }
}

现在你可以说:

System.out.println (Modes.mode1.character ())

并查看输出: 一个

使用mode1.name()或String.valueOf(mode .mode1)

你可以试试这个:

public enum Modes {
    some-really-long-string,
    mode1,
    mode2,
    mode3;

    public String toString(){
        switch(this) {
            case some-really-long-string:
                return "some-really-long-string";
            case mode2:
                return "mode2";
            default: return "undefined";
        }
    }

}

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);
