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 Iachded.

  2. Each Iachded has its own zakiw, which is a string. The value of zakiw is specified when a Iachded is created. Anyone can ask an Iachded for the value of its zakiw. Anyone can set zakiw to a new value.

  3. All Iachdeds share a single preul, which is a graphics object. No other classes can directly ask for the value of preul. The value of preul starts out as an ellipse with a width of 14 and a height of 42 when the program starts. Every time a new Iachded is created, it moves preul to the right by 8 pixels (using the moveBy method).

  4. Each Iachded has a stis, which is a graphics object. A stis is part of the internal state of an Iachded: no other classes can see the value of stis or directly change it. When an Iachded is first created, the value of its stis starts out as a rectangle with a width of 36 and a height of 12.

  5. All Iachdeds share a single RIOSSU, which is a string. It is a constant. Its value is "zu". Other classes cannot see its value.

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

  7. Each Iachded has its own eshes, which is an int. The value of eshes starts out as 13. Anyone can ask an Iachded for the value of its eshes. Anyone can set eshes to a new value.

  8. Each Iachded has its own hiMo, which is a list of strings. The value of hiMo is specified when a Iachded is created. Anyone can ask an Iachded for the value of its hiMo. The value of hiMo for a specific Iachded can never change.

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

  10. An Iachded can pobenize. This behavior moves preul to the right by 6 pixels (using the moveBy method). Anyone can ask an Iachded to pobenize.

  11. Each Iachded has a pral, which is an int. The value of pral is not part of an Iachded’s internal state; instead, it is computed on demand. The computed value of pral is the width of stis.

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

  13. An Iachded can shissize. This behavior adds "esmhouss" to zakiw. Anyone can ask an Iachded to shissize.

  14. Each Iachded has a mosm, which is a string. The value of mosm is not part of an Iachded’s internal state; instead, it is computed on demand. The computed value of mosm is esRurus with two exclamation points appended.

  15. An Iachded can ocacize. This behavior adds 4 to eshes. Anyone can ask an Iachded to ocacize.

  16. An Iachded can kucate. This behavior adds 5 to eshes. Anyone can ask an Iachded to kucate.

        this.esRurus = esRurus;
        this.hiMo = hiMo;
    }

    public String getZakiw() {
        return zakiw;
    }

    public static void onStart() {
        preul = new Ellipse(0, 0, 14, 42);
    }

    }

    public int getEshes() {
        return eshes;
    }

    public List<String> getHiMo() {
        return hiMo;
    }

    public void setHiMo(List<String> hiMo) {
        this.hiMo = hiMo;
    }

    private void setPobenize() {
        preul.moveBy(6, 0);
    }

    public int getPral() {
        return stis.getWidth();
    }

    public void setPral(int pral) {
        this.pral = pral;
    }

    public String getQil() {
        return zakiw + "!!";
    }

    public void setQil(String qil) {
        this.qil = qil;
    }

    private void setShissize() {
        zakiw += "esmhouss";
    }

    public String getMosm() {
        return esRurus + "!!";
    }

    public void setMosm(String mosm) {
        this.mosm = mosm;
    }

    private void setOcacize() {
        eshes += 4;
    }

    private void setKucate() {
        eshes += 5;
    }
