Question

Given the main class Dog, subclass Poodle, and the beginning of the subclass Pug:

Instructions for Pug.java

Variables:

int flabCount – the count of layers on the Pug

An invalid value should default this field to 25.

A value is invalid if it is nonpositive.

boolean isPound – whether this Pug resides in the pound.
Poodle bestFriend- a Poodle who is the best friend with the Pug

Constructors:

A constructor that takes in name, length, weight, stripeCount, isSaltwater, and bestFriend.

The bestFriend argument should be deep copied.

A constructor that takes in no parameters and sets name to “Pluto”, length to 30.0, weight to 320.0, stripeCount to 14, isPound to false, and bestFriend to null.
A copy constructor that deep copies all necessary instance fields.

Methods:

migrate

The pug moves to the opposite kind of living situation if and only if it does not have a best friend.

For example, if this pug were now in a pound and it has a best friend, it would not migrate to a house but instead stay in the pound.

toString

Overrides the corresponding method in its super class, such that a String with the following format is returned without trailing or leading whitespace.
“I’m a talking dog named <name>. My length is <feet> ft <inches> in and my weight is <pounds> lbs <ounces> oz. I’m a {pound/house} pug with <flabCount> layers. I have {no best friend/a best friend} named <bestFriendName>}.”

No getters or setters should be written.

1. Would I do the below to set the default for flabCount?

if(int flabCount < 0)
this.flabcount = 25?

2. Am I creating the migrate method correctly and if so, how would I go about creating the toString method and calling a name from Poodle for it?

3. Is that the correct notation to deep copy bestFriend and is there anything else that needs fixing to match the instructions?
