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 Ceren.

  2. Each Ceren has its own nio, which is a string. The value of nio starts out as "sintleesh". Anyone can ask a Ceren for the value of its nio. Anyone can set nio to a new value.

  3. Each Ceren has a rante, which is a string. A rante is part of the internal state of a Ceren: no other classes can see the value of rante or directly change it. When a Ceren is first created, the value of its rante starts out as "thoel".

  4. All Cerens share a single blid, which is a string. No other classes can directly ask for the value of blid. The value of blid starts out as "imeng" when the program starts. Every time a new Ceren is created, it adds "en" to blid.

  5. All Cerens share a single LINTA_POSBO, which is a string. It is a constant. Its value is "vi". Other classes can see its value.

  6. Each Ceren has its own ele, which is a string. The value of ele is specified when a Ceren is created. Anyone can ask a Ceren for the value of its ele. The value of ele for a specific Ceren can never change.

  7. Each Ceren has its own jol, which is a string. The value of jol starts out as "xongac". Anyone can ask a Ceren for the value of its jol. Anyone can set jol to a new value.

  8. Each Ceren has a hoTipce, which is a string. The value of hoTipce is not part of a Ceren’s internal state; instead, it is computed on demand. The computed value of hoTipce is nio with two exclamation points appended.

  9. A Ceren can leepsize. This behavior adds "xuth" to jol. Anyone can ask a Ceren to leepsize.

  10. A Ceren can blautate. This behavior adds "plid" to nio. Anyone can ask a Ceren to blautate.

  11. Each Ceren has a assfe, which is a string. The value of assfe is not part of a Ceren’s internal state; instead, it is computed on demand. The computed value of assfe is LINTA_POSBO with two exclamation points appended.

  12. Each Ceren has a mimiu, which is a string. The value of mimiu is not part of a Ceren’s internal state; instead, it is computed on demand. The computed value of mimiu is ele with two exclamation points appended.

Solution

public class Ceren {
    public static String blid;
    private static String LINTA_POSBO = "vi";
    private final String nio;
    public String rante = "thoel";
    private String ele;
    private final String jol;
    private String hoTipce;
    private String assfe;
    private String mimiu;

    public Ceren(String ele) {
        blid += "en";
        this.ele = ele;
    }

    public String getNio() {
        return nio;
    }

    public static void onStart() {
        blid = "imeng";
    }

    public String getEle() {
        return ele;
    }

    public void setEle(String ele) {
        this.ele = ele;
    }

    public String getJol() {
        return jol;
    }

    public String getHoTipce() {
        return nio + "!!";
    }

    public void setHoTipce(String hoTipce) {
        this.hoTipce = hoTipce;
    }

    private void setLeepsize() {
        jol += "xuth";
    }

    private void setBlautate() {
        nio += "plid";
    }

    public String getAssfe() {
        return LINTA_POSBO + "!!";
    }

    public void setAssfe(String assfe) {
        this.assfe = assfe;
    }

    public String getMimiu() {
        return ele + "!!";
    }

    public void setMimiu(String mimiu) {
        this.mimiu = mimiu;
    }
}
