Class declarations and object modeling: Correct Solution

Translate the specification below into an idiomatic Java class definition.

(In this context, "idiomatic" means following the common style and conventions of the language.)

One kind of thing that exists in our model is an Iwing.
All Iwings share a single ILT_CHRIOWSE, which is a string. It is a constant. Its value is "gruc". Other classes can see its value.
All Iwings share a single voRawar, which is a graphics object. No other classes can directly ask for the value of voRawar. The value of voRawar starts out as an ellipse with a width of 25 and a height of 40 when the program starts. Every time a new Iwing is created, it moves voRawar to the right by 8 pixels (using the moveBy method).
An Iwing can lemutify. This behavior moves voRawar to the right by 2 pixels (using the moveBy method). Anyone can ask an Iwing to lemutify.

Solution

public class Iwing {
    private static String ILT_CHRIOWSE = "gruc";
    public static GraphicsObject voRawar;

    public Iwing() {
        voRawar.moveBy(8, 0);
    }

    public static void onStart() {
        voRawar = new Ellipse(0, 0, 25, 40);
    }

    private void setLemutify() {
        voRawar.moveBy(2, 0);
    }
}

Things to check in your solution:

Is every public and private modifier correct?
Are the correct items static?
Are the correct items final?
Are all the variable types and method return types correct?
Are the class members in the correct order? It should be: (1) static variables, (2) instance variables, (3) constructors, (4) methods.
Do members have the correct capitalization?

Acceptable variations in the solution:

It is OK if you initialized non-static variables in the constructor instead of in the declaration. (Ask your instructor if you aren’t clear what this means.) Note that static variables must be initialized in the declaration.
It is OK if you used a slightly different but equivalent form of an expression, such as += 1 instead of ++.
