Question

In Java please

Create a class to represent a dog. Name the class “Dog”. It will contain three (3) class attributes, its bark, size, and cuteness.
The bark will be the sound of the dog’s bark, as in “woof!”. Its size will be how tall the dog is from the ground, and that number should always be between 6 and 44 inches. The cuteness is a string describing how cute the dog is, based on this scale:
“ugliest dog ever!”
“pretty ugly dog.”
“ugly dog”
“average”
“cute dog.”
“pretty cute dog.”
“most adorable dog ever!”
Ensure that all of the class variables are private and that they each have an accessor (getter) and a mutator (setter).
Include a default constructor method that takes no parameters but initializes a dog object with a bark sound of “Yelp!”, a size of 20, and a cuteness of “average.”.
Provide an overloaded constructor as well, that will take in three parameters and use those parameters to set all of the class’s fields.
Next, have a method called “UpdateBark” that will change the dog’s cuteness depending on its size, since large dogs can have intimidating deep barks while smaller dogs will have higher pitched and less frightening barks.
If the dog is larger than 16 inches, its cuteness should change in a negative fashion anytime the dog barks (big dogs tend to scare people when they bark). If it is smaller than that, the dog’s cuteness should change in a positive fashion. For example, a larger dog would change from “average.” to “ugly dog.” and a smaller dog would change from “pretty cute!” to “most adorable dog ever!”. The values that you change the cuteness to should come from the list of cuteness above.
We will also have a “toString” method, which will simply return the dog’s bark, size and cuteness.

Create two (2) instances of the “Dog” class in your “Main” method. One will be created using the default constructor and the other should be made using the overloaded constructor.  That means that you should pass the overloaded constructor arguments that come from user input.
Print out each of the dog’s three attributes using the accessors. Then call the “UpdateBark” method for both and print out their fields again, but this time through the “ToString” method.
Example (blue is default dog’s attributes, green is the user’s dog’s):
Creating a default dog…
Finished creating a default dog!
Default dog bark sound is Yelp!
Default dog size is 20 inches.
Default dog’s cuteness is cute dog.
Continued on third page…
Please enter the sound of your dog’s bark: “MOOOOOO!”
Please enter the size of your dog: “10”
Please enter the cuteness of your dog: “ugly dog.”
Your dog bark sound is MOOOOOO!
Your dog size is 10 inches.
Your dog’s cuteness is ugly dog.
Both dogs are doing a scary bark! Their cuteness has been affected!
Default dog bark sound is Yelp!
Default dog size is 20 inches.
Default dog’s cuteness is average.
Your dog bark sound is MOOOOOO!
Your dog size is 10 inches.
Your dog’s cuteness is average.
