如何获取存储在信封中的参考文献? [关闭]
原标题:How to get hold of a reference stored in an enum? [closed]

我有一个 Java enum, 其对象引用存储在字段中 。 如何从 enum 外面 获得该引用?

public enum TisztításiEljárás  {
    BIO_TISZTÍTÁS(new Időtartam(3, 20))

    private Időtartam javasoltVállalás;

    private TisztításiEljárás(Időtartam i) {
        javasoltVállalás = i;
    }
}
最佳回答

就像是班级一样

将字段公之于众,或将 get 方法添加到 enum 中 。

enum TisztításiEljárás  {
    BIO_TISZTÍTÁS(new Időtartam(3, 20));

    private Időtartam javasoltVállalás;

    private TisztításiEljárás(Időtartam i) {
        javasoltVállalás = i;
    }

    public Időtartam getObj() {    // ordinary get method
        return javasoltVállalás;
    }
}

像这样使用它:

// Get the object
Időtartam theObject = TisztításiEljárás.BIO_TISZTÍTÁS.getObj();
问题回答

我不确定我是否完全理解 这个问题,似乎过于简单

您是否尝试过Tisztítási Eljárás.BIO_TISZTTÁÁS ?

如果您需要获取 javasoltVallalás 变量, 您需要为此添加一个公众获取者 。
