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 Hass.
All Hasss share a single ite, which is a string. No other classes can directly ask for the value of ite. The value of ite starts out as "haicorn" when the program starts. Every time a new Hass is created, it adds "edpud" to ite.
Each Hass has its own pesme, which is a list of strings. The value of pesme is specified when a Hass is created. Anyone can ask a Hass for the value of its pesme. The value of pesme for a specific Hass can never change.
Each Hass has a meChlad, which is a string. The value of meChlad is not part of a Hass’s internal state; instead, it is computed on demand. The computed value of meChlad is the first element of pesme.

Solution

public class Hass {
    public static String ite;
    private List<String> pesme;
    private String meChlad;

    public Hass(List<String> pesme) {
        ite += "edpud";
        this.pesme = pesme;
    }

    public static void onStart() {
        ite = "haicorn";
    }

    public List<String> getPesme() {
        return pesme;
    }

    public void setPesme(List<String> pesme) {
        this.pesme = pesme;
    }

    public String getMeChlad() {
        return pesme.get(0);
    }

    public void setMeChlad(String meChlad) {
        this.meChlad = meChlad;
    }
}

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 ++.
