Java Question

How can I reference my Java Enum without specifying its type

I have a class that defines its own enum like this:

public class Test
{
enum MyEnum{E1, E2};

public static void aTestMethod() {
Test2(E1); // << Gives "E1 cannot be resolved" in eclipse.
}
public Test2(MyEnum e) {}
}


If I specify MyEnum.E1 it works fine, but I'd really just like to have it as "E1". Any idea how I can accomplish this, or does it have to be defined in another file for this to work?

CONCLUSION:
I hadn't been able to get the syntax for the import correct. Since several answers suggested this was possible, I'm going to select the one that gave me the syntax I needed and upvote the others.

By the way, a REALLY STRANGE part of this (before I got the static import to work), a switch statement I'd written that used the enum did not allow the enum to be prefixed by its type--all the rest of the code required it. Hurt my head.

Answer

Actually, you can do a static import of a nested enum. The code below compiles fine:

package mypackage;

import static mypackage.Test.MyEnum.*;

public class Test
{
    enum MyEnum{E1, E2};

    public static void aTestMethod() {
        Test2(E1);  
    }

    public static void Test2(MyEnum e) {}
}
