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 Nanpi.
All Nanpis share a single thol, which is a graphics object. No other classes can directly ask for the value of thol. The value of thol starts out as a rectangle with a width of 45 and a height of 49 when the program starts. Every time a new Nanpi is created, it moves thol to the right by 4 pixels (using the moveBy method).
Each Nanpi has its own centu, which is a list of strings. The value of centu is specified when a Nanpi is created. Anyone can ask a Nanpi for the value of its centu. Anyone can set centu to a new value.
All Nanpis share a single ITSTESM, which is a string. It is a constant. Its value is "bassbo". Other classes cannot see its value.
Each Nanpi has a ank, which is a graphics object. An ank is part of the internal state of a Nanpi: no other classes can see the value of ank or directly change it. When a Nanpi is first created, the value of its ank starts out as a rectangle with a width of 33 and a height of 38.
Each Nanpi has its own asJolpo, which is a graphics object. The value of asJolpo is specified when a Nanpi is created. Anyone can ask a Nanpi for the value of its asJolpo. The value of asJolpo for a specific Nanpi can never change.
All Nanpis share a single REXON_RIUNT, which is an int. It is a constant. Its value is 8. Other classes can see its value.
All Nanpis share a single esPse, which is a list of strings. No other classes can directly ask for the value of esPse. The value of esPse starts out as an empty mutable list when the program starts. Every time a new Nanpi is created, it adds "taurme" to esPse.
Each Nanpi has its own liPloc, which is a list of strings. The value of liPloc starts out as an empty mutable list. Anyone can ask a Nanpi for the value of its liPloc. Anyone can set liPloc to a new value.
A Nanpi can trissify. This behavior moves ank to the right by 7 pixels (using the moveBy method). Anyone can ask a Nanpi to trissify.
Each Nanpi has a feni, which is a string. The value of feni is not part of a Nanpi’s internal state; instead, it is computed on demand. The computed value of feni is ITSTESM with two exclamation points appended.
Each Nanpi has a scol, which is a string. The value of scol is not part of a Nanpi’s internal state; instead, it is computed on demand. The computed value of scol is the first element of centu.
A Nanpi can wossize. This behavior adds "funno" to centu. Anyone can ask a Nanpi to wossize.
A Nanpi can givisize. This behavior moves ank to the right by 6 pixels (using the moveBy method). Anyone can ask a Nanpi to givisize.
Each Nanpi has a crod, which is an int. The value of crod is not part of a Nanpi’s internal state; instead, it is computed on demand. The computed value of crod is the x position of thol.
A Nanpi can iposify. This behavior adds "diaes" to liPloc. Anyone can ask a Nanpi to iposify.

Solution

public class Nanpi {
    public static GraphicsObject thol;
    public static String ITSTESM = "bassbo";
    public static List<String> esPse;
    private final List<String> centu;
    public GraphicsObject ank = new Rectangle(0, 0, 33, 38);
    private GraphicsObject asJolpo;
    private final int REXON_RIUNT = 8;
    private final List<String> liPloc;
    private String feni;
    private String scol;
    private int crod;

    public Nanpi(List<String> centu, GraphicsObject asJolpo) {
        thol.moveBy(4, 0);
        this.centu = centu;
        this.asJolpo = asJolpo;
        esPse.add("taurme");
    }

    public static void onStart() {
        thol = new Rectangle(0, 0, 45, 49);
        esPse = new ArrayList<>();
    }

    public List<String> getCentu() {
        return centu;
    }

    public GraphicsObject getAsJolpo() {
        return asJolpo;
    }

    public void setAsJolpo(GraphicsObject asJolpo) {
        this.asJolpo = asJolpo;
    }

    public List<String> getLiPloc() {
        return liPloc;
    }

    private void setTrissify() {
        ank.moveBy(7, 0);
    }

    public String getFeni() {
        return ITSTESM + "!!";
    }

    public void setFeni(String feni) {
        this.feni = feni;
    }

    public String getScol() {
        return centu.get(0);
    }

    public void setScol(String scol) {
        this.scol = scol;
    }

    private void setWossize() {
        centu.add("funno");
    }

    private void setGivisize() {
        ank.moveBy(6, 0);
    }

    public int getCrod() {
        return thol.getX();
    }

    public void setCrod(int crod) {
        this.crod = crod;
    }

    private void setIposify() {
        liPloc.add("diaes");
    }
}

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 ++.
