Java - 枚举与数组字段

问题描述

我想将每个名称的列表名称和个别昵称作为Java中的枚举存储。昵称的数量不会改变。目的是能够从昵称中获取一个全名。目前我已经实现了这样：

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
    }
}

$ b $我非常不喜欢重复 new String [] {...} ，所以我想知道是否有人可以建议一个替代，更简洁的方法来实现这个？

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，

Pete

推荐答案

Vararg参数：

private Names(String... nicknames) {

现在，您可以调用构造函数而不显式创建数组：

Now you can invoke constructor without explicitly creating array:

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

（参见任意参数数部分）
