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 Dosclun.
Each Dosclun has its own osPio, which is a list of strings. The value of osPio is specified when a Dosclun is created. Anyone can ask a Dosclun for the value of its osPio. Anyone can set osPio to a new value.
Each Dosclun has a erVed, which is a graphics object. An erVed is part of the internal state of a Dosclun: no other classes can see the value of erVed or directly change it. When a Dosclun is first created, the value of its erVed starts out as a rectangle with a width of 32 and a height of 18.
All Doscluns share a single cemco, which is a graphics object. No other classes can directly ask for the value of cemco. The value of cemco starts out as a rectangle with a width of 10 and a height of 26 when the program starts. Every time a new Dosclun is created, it moves cemco to the right by 4 pixels (using the moveBy method).
A Dosclun can angify. This behavior moves cemco to the right by 8 pixels (using the moveBy method). Anyone can ask a Dosclun to angify.
Each Dosclun has a loou, which is an int. The value of loou is not part of a Dosclun’s internal state; instead, it is computed on demand. The computed value of loou is the width of erVed.

Solution

public class Dosclun {
    public static GraphicsObject cemco;
    private final List<String> osPio;
    public GraphicsObject erVed = new Rectangle(0, 0, 32, 18);
    private int loou;

    public Dosclun(List<String> osPio) {
        this.osPio = osPio;
        cemco.moveBy(4, 0);
    }

    public List<String> getOsPio() {
        return osPio;
    }

    public static void onStart() {
        cemco = new Rectangle(0, 0, 10, 26);
    }

    private void setAngify() {
        cemco.moveBy(8, 0);
    }

    public int getLoou() {
        return erVed.getWidth();
    }

    public void setLoou(int loou) {
        this.loou = loou;
    }
}

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 ++.
