Hi there,
can someone help me developing only the
class Parrot in JAVA please? Class Bird is provided already in the
testing environment. I do not want to reimplement code from Bird in
the Parrot class.
This question concerns a class called Parrot to be
developed as a subclass of the class Bird (click to view
this file), which has already been developed.
Birds have a name,
a description, a favouriteFood and a
vocabulary. By default a bird's vocabulary does not contain
any phrases.
Parrots are birds that may have some phrases in their vocabulary,
and they may be talking or not talking.
(a) Add the class Parrot in the answer box below, making
it a subclass of Bird.
(b) Add a private instance variable to the class called
talking of type boolean.
(c) Add a public constructor for Parrot whose first
parameter is used to set the parrot's name and whose second
parameter is the parrot's description.
The instance variable talking should be set to
false
(d) Add standard getter and setter methods for talking
called isTalking and setTalking.
(e) Add a public method addPhrase that adds the string
phrase passed as argument to vocabulary. The method does not
return a value.
(f) Add a public method sayPhrase that does not return a
value and takes a string argument representing a phrase the parrot
might say. It should have the following effects depending on the
value of talking and whether the phrase is in vocabulary or
not:
(g) Add a public method updateFavouriteFood which takes
a String argument and does not return a value. The method should
prefix the parrot's favourite food with the String passed as
argument and a space.
E.g. If favouriteFood is currently set to "seeds" and
the argument passed is "sunflower" then the method should set
favouriteFood to "sunflower seeds".
(h) Override the toString method inherited from Bird to
add the text:
" and is talking" or " and is not talking"
depending on the value of talking.
(i) Add a public method resetFavouriteFood that takes no
argument and does not return a value. It should reset the parrot's
favourite food to the characters after the first space if any in
favouriteFood. If there is no space the favourite food should be
unchanged.
E.g. if the favourite food is currently "sunflower seeds" then
the method should reset this to "seeds".
For example:
