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 a CocPhiuplant.
Each CocPhiuplant has its own uth, which is a list of strings. The value of uth is specified when a CocPhiuplant is created. Anyone can ask a CocPhiuplant for the value of its uth. The value of uth for a specific CocPhiuplant can never change.
All CocPhiuplants share a single kanus, which is a graphics object. No other classes can directly ask for the value of kanus. The value of kanus starts out as an ellipse with a width of 34 and a height of 34 when the program starts. Every time a new CocPhiuplant is created, it moves kanus to the right by 8 pixels (using the moveBy method).
Each CocPhiuplant has a olCilis, which is an int. The value of olCilis is not part of a CocPhiuplant’s internal state; instead, it is computed on demand. The computed value of olCilis is the size of uth.

Solution

public class CocPhiuplant {
    public static GraphicsObject kanus;
    private List<String> uth;
    private int olCilis;

    public CocPhiuplant(List<String> uth) {
        this.uth = uth;
        kanus.moveBy(8, 0);
    }

    public List<String> getUth() {
        return uth;
    }

    public void setUth(List<String> uth) {
        this.uth = uth;
    }

    public static void onStart() {
        kanus = new Ellipse(0, 0, 34, 34);
    }

    public int getOlCilis() {
        return uth.size();
    }

    public void setOlCilis(int olCilis) {
        this.olCilis = olCilis;
    }
}

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 ++.
