如何为枚举的每个条目添加描述？

Question

鉴于以下内容:

enum Moving {DownRight , UpRight ,DownLeft ,UpLeft ,Up , Down ,Left ,Right};

Moving m_moving;

如果我这样做:

m_moving = Moving.DownRight;

和

m_moving.toString();

然后我会得到:

DownRight

那么,如何为枚举中的每个条目添加描述？

例如,如果我这样做,m_moving.toString();那么我想要呈现FOO BAR.

谢谢

Answer 1

从我们的应用程序中查看此代码

public enum RegimeTributario {
    SIMPLES_NACIONAL("SI"), 
    LUCRO_PRESUMIDO("LP"), 
    LUCRO_REAL("LR");

    private String sigla;

    private RegimeTributario(String sigla) {
        this.sigla = sigla;
    }

    public String getSigla() {
        return sigla;
    }
}

枚举也接受字段

Answer 2

在这篇文章之后，这是我的最终答案（也非常感谢@Luiz E.）：

enum DirectionsEnum {

    North("North"),
    NorthEast("North East"),
    East("East"),
    SouthEast("South East"),
    South("South"),
    SouthWest("South West"),
    West("West"),
    NorthWest("North West");

    private String value;

    DirectionsEnum(String value) {
        this.value = value;
    }

    public String getValue() {
        return value;
    }

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

    public static DirectionsEnum getEnum(String value) {
        if(value == null)
            throw new IllegalArgumentException();
        for(DirectionsEnum v : values())
            if(value.equalsIgnoreCase(v.getValue())) return v;
        throw new IllegalArgumentException();
    }
}
