Hmmm, interesting.

So what would be the equivalent to:

public enum RandomEnum2 {
   VALUE1(1),
   VALUE2(2);

   private int myVal;

   private RandomEnum2(int value)
   {
      myVal = value;
   }

   public int getValue()
   {
      return myVal;
   }
}

public final class RandomEnum2 extends Enum {
    public static final RandomEnum2 VALUE1 = new RandomEnum2(1);
    public static final RandomEnum2 VALUE2 = new RandomeEnum2(2);

    private int myVal;

    private RandomEnum2(int value)
    {
       myVal = value;
    }

    public int getValue()
    {
       return myVal;
    }
}

I only changed the first three lines. Then you need to add the static
methods that Enum requires.

public final class RandomEnum2 extends Enum {
    public static final RandomEnum2 VALUE1 = new RandomEnum2(1);
    public static final RandomEnum2 VALUE2 = new RandomeEnum2(2);

    private int myVal;

    private RandomEnum2(int value)
    {
       myVal = value;
    }

    public int getValue()
    {
       return myVal;
    }

    public static RandomEnum2[] values() {
        return new RandomEnum2[] {VALUE1, VALUE2};
    }

    public static RandomEnum2 valueOf(String name) {
        return Enum.valueOf(RandomEnum2.class, name);
    }

}
