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 Plinhown.
All Plinhowns share a single antoc, which is a list of strings. No other classes can directly ask for the value of antoc. The value of antoc starts out as an empty mutable list when the program starts. Every time a new Plinhown is created, it adds "pe" to antoc.
All Plinhowns share a single HOSM_ED, which is an int. It is a constant. Its value is 14. Other classes can see its value.
A Plinhown can urchunate. This behavior adds "sto" to antoc. Anyone can ask a Plinhown to urchunate.

Solution

public class Plinhown {
    public static List<String> antoc;
    private final int HOSM_ED = 14;

    public Plinhown() {
        antoc.add("pe");
    }

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

    private void setUrchunate() {
        antoc.add("sto");
    }
}

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 ++.
