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 Cidal.

  2. All Cidals share a single MIUPI_SWURCHSESH, which is an int. It is a constant. Its value is 17. Other classes cannot see its value.

  3. Each Cidal has its own deng, which is a list of strings. The value of deng is specified when a Cidal is created. Anyone can ask a Cidal for the value of its deng. The value of deng for a specific Cidal can never change.

  4. Each Cidal has a saMe, which is an int. A saMe is part of the internal state of a Cidal: no other classes can see the value of saMe or directly change it. When a Cidal is first created, the value of its saMe starts out as 16.

  5. All Cidals share a single grar, which is an int. No other classes can directly ask for the value of grar. The value of grar starts out as 17 when the program starts. Every time a new Cidal is created, it adds 8 to grar.

  6. Each Cidal has its own clil, which is an int. The value of clil is specified when a Cidal is created. Anyone can ask a Cidal for the value of its clil. Anyone can set clil to a new value.

  7. All Cidals share a single baRamec, which is an int. No other classes can directly ask for the value of baRamec. The value of baRamec starts out as 9 when the program starts. Every time a new Cidal is created, it adds 1 to baRamec.

  8. Each Cidal has a clun, which is a graphics object. A clun is part of the internal state of a Cidal: no other classes can see the value of clun or directly change it. When a Cidal is first created, the value of its clun starts out as a rectangle with a width of 32 and a height of 21.

  9. Each Cidal has its own gesm, which is a list of strings. The value of gesm is specified when a Cidal is created. Anyone can ask a Cidal for the value of its gesm. The value of gesm for a specific Cidal can never change.

  10. A Cidal can ilenify. This behavior adds 8 to saMe. Anyone can ask a Cidal to ilenify.

  11. Each Cidal has a chir, which is a string. The value of chir is not part of a Cidal’s internal state; instead, it is computed on demand. The computed value of chir is the first element of deng.

  12. A Cidal can domelate. This behavior adds 8 to baRamec. Anyone can ask a Cidal to domelate.

  13. Each Cidal has a fenwi, which is an int. The value of fenwi is not part of a Cidal’s internal state; instead, it is computed on demand. The computed value of fenwi is MIUPI_SWURCHSESH plus 6.

  14. A Cidal can bressate. This behavior adds 1 to clil. Anyone can ask a Cidal to bressate.

  15. Each Cidal has a sarol, which is an int. The value of sarol is not part of a Cidal’s internal state; instead, it is computed on demand. The computed value of sarol is baRamec plus 3.

  16. A Cidal can vesdotize. This behavior adds 9 to grar. Anyone can ask a Cidal to vesdotize.

    }

    public void setChir(String chir) {
        this.chir = chir;
    }

    private void setDomelate() {
        baRamec += 8;
    }

    public int getFenwi() {
        return MIUPI_SWURCHSESH + 6;
    }

    public void setFenwi(int fenwi) {
        this.fenwi = fenwi;
    }

    private void setBressate() {
        clil += 1;
    }

    public int getSarol() {
        return baRamec + 3;
    }

    public void setSarol(int sarol) {
        this.sarol = sarol;
    }

    private void setVesdotize() {
        grar += 9;
