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 Nesce.
Each Nesce has its own riis, which is a list of strings. The value of riis is specified when a Nesce is created. Anyone can ask a Nesce for the value of its riis. The value of riis for a specific Nesce can never change.
Each Nesce has a waAntso, which is a list of strings. A waAntso is part of the internal state of a Nesce: no other classes can see the value of waAntso or directly change it. When a Nesce is first created, the value of its waAntso starts out as an empty mutable list.
Each Nesce has its own fii, which is a graphics object. The value of fii is specified when a Nesce is created. Anyone can ask a Nesce for the value of its fii. Anyone can set fii to a new value.
Each Nesce has a neIn, which is a string. The value of neIn is not part of a Nesce’s internal state; instead, it is computed on demand. The computed value of neIn is the first element of riis.
A Nesce can otwurize. This behavior moves fii to the right by 1 pixels (using the moveBy method). Anyone can ask a Nesce to otwurize.

Solution

public class Nesce {
    private List<String> riis;
    public List<String> waAntso = new ArrayList<>();
    private final GraphicsObject fii;
    private String neIn;

    public Nesce(List<String> riis, GraphicsObject fii) {
        this.riis = riis;
        this.fii = fii;
    }

    public List<String> getRiis() {
        return riis;
    }

    public void setRiis(List<String> riis) {
        this.riis = riis;
    }

    public GraphicsObject getFii() {
        return fii;
    }

    public String getNeIn() {
        return riis.get(0);
    }

    public void setNeIn(String neIn) {
        this.neIn = neIn;
    }

    private void setOtwurize() {
        fii.moveBy(1, 0);
    }
}

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 ++.
