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 Biongbism.
Each Biongbism has a bimu, which is a list of strings. A bimu is part of the internal state of a Biongbism: no other classes can see the value of bimu or directly change it. When a Biongbism is first created, the value of its bimu starts out as an empty mutable list.
Each Biongbism has its own recil, which is a list of strings. The value of recil starts out as an empty mutable list. Anyone can ask a Biongbism for the value of its recil. Anyone can set recil to a new value.
A Biongbism can bicilize. This behavior adds "olprir" to recil. Anyone can ask a Biongbism to bicilize.

Solution

public class Biongbism {
    public List<String> bimu = new ArrayList<>();
    private final List<String> recil;

    public Biongbism() {
    }

    public List<String> getRecil() {
        return recil;
    }

    private void setBicilize() {
        recil.add("olprir");
    }
}

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 ++.
