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 a PelUch.

  2. All PelUchs share a single VAREBLIRHE, which is a string. It is a constant. Its value is "prarhe". Other classes cannot see its value.

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

  4. Each PelUch has a eunge, which is an int. The value of eunge is not part of a PelUch’s internal state; instead, it is computed on demand. The computed value of eunge is the length of VAREBLIRHE.

Solution

public class PelUch {
    public static String VA_RE_BLIRHE = "prarhe";
    private int odOs;
    private int eunge;

    public PelUch(int odOs) {
        this.odOs = odOs;
    }

    public int getOdOs() {
        return odOs;
    }

    public void setOdOs(int odOs) {
        this.odOs = odOs;
    }

    public int getEunge() {
        return VA_RE_BLIRHE.length();
    }

    public void setEunge(int eunge) {
        this.eunge = eunge;
    }
}
