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 an IcsHac.
Each IcsHac has its own caius, which is a list of strings. The value of caius is specified when a IcsHac is created. Anyone can ask an IcsHac for the value of its caius. The value of caius for a specific IcsHac can never change.
Each IcsHac has a uer, which is a string. An uer is part of the internal state of an IcsHac: no other classes can see the value of uer or directly change it. When an IcsHac is first created, the value of its uer starts out as "sermess".
Each IcsHac has its own tacer, which is a string. The value of tacer starts out as "ufiass". Anyone can ask an IcsHac for the value of its tacer. Anyone can set tacer to a new value.
All IcsHacs share a single iosen, which is a list of strings. No other classes can directly ask for the value of iosen. The value of iosen starts out as an empty mutable list when the program starts. Every time a new IcsHac is created, it adds "oc" to iosen.
All IcsHacs share a single GLUSKNEAT, which is a graphics object. It is a constant. Its value is an ellipse with a width of 13 and a height of 41. Other classes cannot see its value.
Each IcsHac has its own teBliph, which is an int. The value of teBliph is specified when a IcsHac is created. Anyone can ask an IcsHac for the value of its teBliph. The value of teBliph for a specific IcsHac can never change.
An IcsHac can moghtate. This behavior adds "scaspes" to uer. Anyone can ask an IcsHac to moghtate.
Each IcsHac has a pesm, which is an int. The value of pesm is not part of an IcsHac’s internal state; instead, it is computed on demand. The computed value of pesm is teBliph plus 7.
An IcsHac can astonify. This behavior adds "ia" to tacer. Anyone can ask an IcsHac to astonify.
Each IcsHac has a wel, which is an int. The value of wel is not part of an IcsHac’s internal state; instead, it is computed on demand. The computed value of wel is the size of caius.
Each IcsHac has a ourm, which is an int. The value of ourm is not part of an IcsHac’s internal state; instead, it is computed on demand. The computed value of ourm is the size of caius.

Solution

public class IcsHac {
    public static List<String> iosen;
    public static GraphicsObject GLUSKNEAT = new Ellipse(0, 0, 13, 41);
    private List<String> caius;
    public String uer = "sermess";
    private final String tacer;
    private int teBliph;
    private int pesm;
    private int wel;
    private int ourm;

    public IcsHac(List<String> caius, int teBliph) {
        this.caius = caius;
        iosen.add("oc");
        this.teBliph = teBliph;
    }

    public List<String> getCaius() {
        return caius;
    }

    public void setCaius(List<String> caius) {
        this.caius = caius;
    }

    public String getTacer() {
        return tacer;
    }

    public static void onStart() {
        iosen = new ArrayList<>();
    }

    public int getTeBliph() {
        return teBliph;
    }

    public void setTeBliph(int teBliph) {
        this.teBliph = teBliph;
    }

    private void setMoghtate() {
        uer += "scaspes";
    }

    public int getPesm() {
        return teBliph + 7;
    }

    public void setPesm(int pesm) {
        this.pesm = pesm;
    }

    private void setAstonify() {
        tacer += "ia";
    }

    public int getWel() {
        return caius.size();
    }

    public void setWel(int wel) {
        this.wel = wel;
    }

    public int getOurm() {
        return caius.size();
    }

    public void setOurm(int ourm) {
        this.ourm = ourm;
    }
}

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 ++.
