why enum could not be resolved in JAVA?

Question

I was using J2EE Eclipse Indigo, and I have three class declare like this:

public interface ClassA {
   public static enum TYPE { TYPE1, TYPE2 };
}

public i         


        

Answer 1

You must write code either in a method or in a static block (assigning static values). Your System.out.println() is written into a class. Create method and put System.out.println() there.

Answer 2

You mistyped inteface for interface.

Maybe your compiler is too old, so that it doesn't know that enum is a keyword.

Answer 3

• the first compiles fine. Check your compiler level (should be at least 1.5)
• inteRface
• you cannot put code in the method body, as you did in ClassC. It should be in a method or in a block

Answer 4

I had a similar problem:

enum can't be resolved to a type

Eclipse offered to import Enum instead.

I went to

• Preferences->Java->Installed_JREs->Execution_environment;
• Selected JavaSE-1.6 in "Execution Environments" pane; and
• Checked jre6 in Compatible JREs pane.

After rebuild enum was recognized properly.
