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;
}
}

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