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 Ciza.
Each Ciza has its own jeFump, which is a list of strings. The value of jeFump is specified when a Ciza is created. Anyone can ask a Ciza for the value of its jeFump. Anyone can set jeFump to a new value.
All Cizas share a single tisi, which is a graphics object. No other classes can directly ask for the value of tisi. The value of tisi starts out as an ellipse with a width of 33 and a height of 31 when the program starts. Every time a new Ciza is created, it moves tisi to the right by 9 pixels (using the moveBy method).
Each Ciza has a weNi, which is an int. The value of weNi is not part of a Ciza’s internal state; instead, it is computed on demand. The computed value of weNi is the width of tisi.

Solution

public class Ciza {
    public static GraphicsObject tisi;
    private final List<String> jeFump;
    private int weNi;

    public Ciza(List<String> jeFump) {
        this.jeFump = jeFump;
        tisi.moveBy(9, 0);
    }

    public List<String> getJeFump() {
        return jeFump;
    }

    public static void onStart() {
        tisi = new Ellipse(0, 0, 33, 31);
    }

    public int getWeNi() {
        return tisi.getWidth();
    }

    public void setWeNi(int weNi) {
        this.weNi = weNi;
    }
}

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 ++.
