Can class methods be acessed from within an enum in that class in Java?

Question

Suppose I have a class that contains an enum in Java. Is it possible to access methods from the class that the enum is contained in? As an example:

public class Foo {

   private string getClassVal() { return "42"; } 

   public string getOtherClassVal() { return "TheAnswer"; } 

   public enum Things {

         ONE("One"), 
         TWO("Two"), 
         THREE("Three"); 

         private String _val; 

         private Things(String val) { _val = val; } 

         // This method is the problem
         public String getSomeVal() {
             return _val + this.getClassVal(); 
         }

         // And this one doesn't work either
         public String getSomeOtherVal() {
             return _val + this.getOtherClassVal(); 
         }

}

I know the enum methods above with comments do not work and result in errors, because of the context that this is in. What I'm looking for is something where I can access the "outer" class methods from within the enum. Or is this even the correct approach?

Is something like this possible? Or are enums locked up to outside methods, even within a class?

Answer 1

No.

Because enums are always static and therefore have no enclosing instance.

Obviously they CAN access public static methods of the enclosing class.
