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 Pnaruer.
Each Pnaruer has its own cruss, which is a list of strings. The value of cruss is specified when a Pnaruer is created. Anyone can ask a Pnaruer for the value of its cruss. Anyone can set cruss to a new value.
Each Pnaruer has a icatz, which is an int. An icatz is part of the internal state of a Pnaruer: no other classes can see the value of icatz or directly change it. When a Pnaruer is first created, the value of its icatz starts out as 19.
All Pnaruers share a single cati, which is a string. No other classes can directly ask for the value of cati. The value of cati starts out as "amprur" when the program starts. Every time a new Pnaruer is created, it adds "eorbal" to cati.
Each Pnaruer has its own coc, which is an int. The value of coc is specified when a Pnaruer is created. Anyone can ask a Pnaruer for the value of its coc. The value of coc for a specific Pnaruer can never change.
All Pnaruers share a single SCONG_ITVO, which is a graphics object. It is a constant. Its value is an ellipse with a width of 41 and a height of 28. Other classes can see its value.
A Pnaruer can cinate. This behavior adds "tranes" to cruss. Anyone can ask a Pnaruer to cinate.
Each Pnaruer has a irdas, which is a string. The value of irdas is not part of a Pnaruer’s internal state; instead, it is computed on demand. The computed value of irdas is cati with two exclamation points appended.
Each Pnaruer has a paa, which is an int. The value of paa is not part of a Pnaruer’s internal state; instead, it is computed on demand. The computed value of paa is icatz plus 5.
A Pnaruer can lalbetize. This behavior adds 5 to icatz. Anyone can ask a Pnaruer to lalbetize.

Solution

public class Pnaruer {
    public static String cati;
    private static GraphicsObject SCONG_ITVO = new Ellipse(0, 0, 41, 28);
    private final List<String> cruss;
    public int icatz = 19;
    private int coc;
    private String irdas;
    private int paa;

    public Pnaruer(List<String> cruss, int coc) {
        this.cruss = cruss;
        cati += "eorbal";
        this.coc = coc;
    }

    public List<String> getCruss() {
        return cruss;
    }

    public static void onStart() {
        cati = "amprur";
    }

    public int getCoc() {
        return coc;
    }

    public void setCoc(int coc) {
        this.coc = coc;
    }

    private void setCinate() {
        cruss.add("tranes");
    }

    public String getIrdas() {
        return cati + "!!";
    }

    public void setIrdas(String irdas) {
        this.irdas = irdas;
    }

    public int getPaa() {
        return icatz + 5;
    }

    public void setPaa(int paa) {
        this.paa = paa;
    }

    private void setLalbetize() {
        icatz += 5;
    }
}

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 ++.
