此方法适用于任何枚举:

public enum MyEnum {
    VALUE1,
    VALUE2,
    VALUE3;

    public int getValue() {
        return this.ordinal();
    }

    public static DataType forValue(int value) {
        return values()[value];
    }

    public String toString() {
        return forValue(getValue()).name();
    }
}

你可以简单地使用:

""+ Modes.mode1

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

正如Benny Neugebauer提到的，您可以覆盖toString()。然而，取而代之的是为每个枚举字段重写toString，我更喜欢这样:

public enum Country{
    SPAIN("España"),
    ITALY("Italia"),
    PORTUGAL("Portugal");


    private String value;

    Country(final String value) {
        this.value = value;
    }

    public String getValue() {
        return value;
    }

    @Override
    public String toString() {
        return this.getValue();
    }
}

您还可以添加一个静态方法来检索所有字段，打印所有字段，等等。 只需调用getValue来获取与每个Enum项关联的字符串

public enum Environment
{
    PROD("https://prod.domain.com:1088/"),
    SIT("https://sit.domain.com:2019/"),
    CIT("https://cit.domain.com:8080/"),
    DEV("https://dev.domain.com:21323/");

    private String url;

    Environment(String envUrl) {
        this.url = envUrl;
    }

    public String getUrl() {
        return url;
    }
}

String prodUrl = Environment.PROD.getUrl();

它将打印:

https://prod.domain.com:1088/

这种枚举字符串常量的设计在大多数情况下都有效。

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;
    }



};
