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.)

  1. One kind of thing that exists in our model is an EeiPrubu.

  2. Each EeiPrubu has its own ioc, which is an int. The value of ioc is specified when a EeiPrubu is created. Anyone can ask an EeiPrubu for the value of its ioc. The value of ioc for a specific EeiPrubu can never change.

  3. Each EeiPrubu has its own aoGle, which is a list of strings. The value of aoGle starts out as an empty mutable list. Anyone can ask an EeiPrubu for the value of its aoGle. Anyone can set aoGle to a new value.

  4. All EeiPrubus share a single SISTPA, which is a list of strings. It is a constant. Its value is ["fralooss", "sa", "a"]. Other classes can see its value.

  5. Each EeiPrubu has a reAs, which is a string. A reAs is part of the internal state of an EeiPrubu: no other classes can see the value of reAs or directly change it. When an EeiPrubu is first created, the value of its reAs starts out as "mocdaen".

  6. An EeiPrubu can prasize. This behavior adds "ul" to reAs. Anyone can ask an EeiPrubu to prasize.

  7. Each EeiPrubu has a vislo, which is a string. The value of vislo is not part of an EeiPrubu’s internal state; instead, it is computed on demand. The computed value of vislo is reAs with two exclamation points appended.

  8. An EeiPrubu can neialify. This behavior adds "iththe" to aoGle. Anyone can ask an EeiPrubu to neialify.

Solution

public class EeiPrubu {
    private static List<String> SISTPA = List.of("fralooss", "sa", "a");
    private int ioc;
    private final List<String> aoGle;
    public String reAs = "mocdaen";
    private String vislo;

    public EeiPrubu(int ioc) {
        this.ioc = ioc;
    }

    public int getIoc() {
        return ioc;
    }

    public void setIoc(int ioc) {
        this.ioc = ioc;
    }

    public List<String> getAoGle() {
        return aoGle;
    }

    private void setPrasize() {
        reAs += "ul";
    }

    public String getVislo() {
        return reAs + "!!";
    }

    public void setVislo(String vislo) {
        this.vislo = vislo;
    }

    private void setNeialify() {
        aoGle.add("iththe");
    }
}
