Good night guys,

I wanted to ask, why it's not possible, to print out the content of an enumeration without a for loop.

For example this:

public class NurTests {

    enum optionen{
       Option1, Option2, Option3;
    }

  public static void main(String[] args) {

    for (optionen d: optionen.values()){
        System.out.println(d);
    }
  }
}

Why can't I write this? Or why can't I write System.out.println(optionen) either?

System.out.println(optionen.values());

Thanks in advance.

What happens when you try it? – President James K. Polk Jul 23 '17 at 20:09

`System.out.println(Arrays.toString(optionen.values()));` – Elliott Frisch Jul 23 '17 at 20:11
So when I write System.out.println(optionen); the compiler (IntelliJ) tells me that it's not an expression. And if I write System.out.println(optionen.values()) it prints [LNurTests$optionen;@7852e922. If I do it with the for loop it works. – NewbieJava Jul 23 '17 at 20:12
Becuase for an enum, `values()` returns an array, not a `String` – hbagdi Jul 23 '17 at 20:14
