爪哇 - 枚举与数组字段 [英] Java - Enum with array field

问题描述

我要存储一个列表名称和个人昵称为每名枚举在Java中。昵称的数目将不会发生变化。的目的是为了能够从一个昵称获取全名。目前，我已经实现了这个像这样：

I want to store a list names and individual nicknames for each name as an Enum in Java. The number of nicknames will not vary. The purpose is to be able to get a full name from a nickname. Currently I have implemented this like so:

public enum Names {

    ELIZABETH(new String[] {"Liz","Bet"}),    
    ...
    ;

    private String[] nicknames;

    private Names(String[] nicknames)
    {
        this.nicknames = nicknames
    }


    public Names getNameFromNickname(String nickname) {
       //Obvious how this works
    }
}

我不喜欢比较有重复新的String [] {...} ，所以我想知道如果任何人都可以提出一个替代方案，更简洁，实施这一方法？

I quite dislike having to repeat new String[] {...}, so I wondered if anyone could suggest an alternative, more concise, method of implementing this?

干杯，

皮特

推荐答案

VARARG参数：

private Names(String... nicknames) {

现在您可以调用构造函数没有明确创建数组：

Now you can invoke constructor without explicitly creating array:

ELIZABETH("Liz", "Bet", "another name")

详细（见的参数的任意数）
