Question

Given the main class Dog.java and the following subclass Poodle.java:

Instructions for Poodle.java:

Variables:

Double whiskerLength – the length of the dog’s longest whisker in inches

An invalid value should default this field to 8.0.
A value is invalid if it is not a number, infinite, nonpositive, or null.

Constructors:

A constructor that takes in name, length, weight, and whiskerLength.
A constructor that takes in no parameters and sets name to “Bluu”, length to 52.0, weight to 720.0, and whiskerLength to 5.0.
A copy constructor that deep copies all necessary instance fields.

Methods:

isHairy

Returns a boolean reflecting if the dog is hairy.
A dog is said to be hairy if its longest whisker is longer than its end-to-end length.

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 poodle whose longest whisker is <whiskerLength>, so I {am/am not} shaggy.”

Setter for whiskerLength.

If the input is invalid, set the field to its default value

1. How do I go about creating the setter to check for invalid inputs, and incorportating it into Constructor A.

2. Is there a way to call the toString in Dog.java and combining with the "I'm a Poodle whos longest whisker..." part of the toString in Poodle.java
3. Overall is there anything else that should be improved/cleaned up?
