(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 talkingcalled 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 "poppy" then the method should set favouriteFood to "poppy seeds".
" 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 "poppy seeds" then the method should reset this to "seeds".
