Java - 带有数组字段的枚举
我想将列表名称和每个名称的单独昵称存储为 Java 中的枚举。昵称的数量不会变化。目的是能够从昵称中得到全名。目前我已经这样实现了：
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
}
}
我非常不喜欢重复 new String[] {...}，所以我想知道是否有人可以建议一种替代的、更简洁的实现方法？
干杯，
皮特
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
}
}
I quite dislike having to repeat new String[] {...}, so I wondered if anyone could suggest an alternative, more concise, method of implementing this?
Cheers,
Pete

可变参数：
现在您可以调用构造函数而无需显式创建数组：
详细信息（参见“任意数量的参数”部分）
Vararg parameters:
Now you can invoke constructor without explicitly creating array:
