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 Mirack.

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

  3. All Miracks share a single SESSPHIA, which is a string. It is a constant. Its value is "eossdu". Other classes can see its value.

  4. All Miracks share a single edReeng, which is a graphics object. No other classes can directly ask for the value of edReeng. The value of edReeng starts out as an ellipse with a width of 26 and a height of 48 when the program starts. Every time a new Mirack is created, it moves edReeng to the right by 1 pixels (using the moveBy method).

  5. Each Mirack has a aekes, which is a graphics object. An aekes is part of the internal state of a Mirack: no other classes can see the value of aekes or directly change it. When a Mirack is first created, the value of its aekes starts out as an ellipse with a width of 19 and a height of 35.

  6. Each Mirack has its own taHimo, which is a list of strings. The value of taHimo is specified when a Mirack is created. Anyone can ask a Mirack for the value of its taHimo. Anyone can set taHimo to a new value.

  7. Each Mirack has a wre, which is a list of strings. A wre is part of the internal state of a Mirack: no other classes can see the value of wre or directly change it. When a Mirack is first created, the value of its wre starts out as an empty mutable list.

  8. Each Mirack has its own uthol, which is a graphics object. The value of uthol is specified when a Mirack is created. Anyone can ask a Mirack for the value of its uthol. The value of uthol for a specific Mirack can never change.

  9. Each Mirack has its own iwkca, which is a graphics object. The value of iwkca starts out as a rectangle with a width of 33 and a height of 11. Anyone can ask a Mirack for the value of its iwkca. Anyone can set iwkca to a new value.

  10. A Mirack can fisealize. This behavior adds "manko" to wre. Anyone can ask a Mirack to fisealize.

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

  12. A Mirack can ehisate. This behavior moves edReeng to the right by 9 pixels (using the moveBy method). Anyone can ask a Mirack to ehisate.

  13. Each Mirack has a esPhuss, which is an int. The value of esPhuss is not part of a Mirack’s internal state; instead, it is computed on demand. The computed value of esPhuss is the width of uthol.

  14. A Mirack can stootate. This behavior moves iwkca to the right by 9 pixels (using the moveBy method). Anyone can ask a Mirack to stootate.

  15. Each Mirack has a acAn, which is an int. The value of acAn is not part of a Mirack’s internal state; instead, it is computed on demand. The computed value of acAn is the width of iwkca.

  16. A Mirack can suenify. This behavior moves aekes to the right by 2 pixels (using the moveBy method). Anyone can ask a Mirack to suenify.
