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 Fanwec.

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

  3. All Fanwecs share a single CALIMA, which is a graphics object. It is a constant. Its value is an ellipse with a width of 18 and a height of 25. Other classes can see its value.

  4. Each Fanwec has its own anme, which is a string. The value of anme starts out as "cet". Anyone can ask a Fanwec for the value of its anme. Anyone can set anme to a new value.

  5. All Fanwecs share a single wor, which is a list of strings. No other classes can directly ask for the value of wor. The value of wor starts out as an empty mutable list when the program starts. Every time a new Fanwec is created, it adds "blawur" to wor.

  6. Each Fanwec has a psask, which is an int. A psask is part of the internal state of a Fanwec: no other classes can see the value of psask or directly change it. When a Fanwec is first created, the value of its psask starts out as 8.

  7. Each Fanwec has a ider, which is an int. An ider is part of the internal state of a Fanwec: no other classes can see the value of ider or directly change it. When a Fanwec is first created, the value of its ider starts out as 15.

  8. All Fanwecs share a single ucor, which is a list of strings. No other classes can directly ask for the value of ucor. The value of ucor starts out as an empty mutable list when the program starts. Every time a new Fanwec is created, it adds "pinsphed" to ucor.

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

  10. Each Fanwec has a piIngbe, which is an int. The value of piIngbe is not part of a Fanwec’s internal state; instead, it is computed on demand. The computed value of piIngbe is psask plus 4.

  11. A Fanwec can larponate. This behavior adds 7 to ider. Anyone can ask a Fanwec to larponate.

  12. Each Fanwec has a uisa, which is an int. The value of uisa is not part of a Fanwec’s internal state; instead, it is computed on demand. The computed value of uisa is ider plus 7.

  13. A Fanwec can aissify. This behavior adds "ventsar" to anme. Anyone can ask a Fanwec to aissify.

  14. Each Fanwec has a sless, which is an int. The value of sless is not part of a Fanwec’s internal state; instead, it is computed on demand. The computed value of sless is psask plus 8.

  15. A Fanwec can inkodify. This behavior adds 6 to psask. Anyone can ask a Fanwec to inkodify.

  16. Each Fanwec has a neght, which is an int. The value of neght is not part of a Fanwec’s internal state; instead, it is computed on demand. The computed value of neght is ider plus 2.
