Question

Create a Policy class that will model an insurance policy for one person.

Use the following guidelines to create the Policy class:
• An insurance policy has the following attributes:
○ Policy Number
○ Provider Name
○ Policyholder's First Name
○ Policyholder's Last Name
○ Policyholder's Age
○ Policyholder's Smoking Status (will be "smoker" or "non-smoker")
○ Policyholder's Height (in inches)
○ Policyholder's Weight (in pounds)
• Include a no-arg constructor (set default values for all fields).
• Include a constructor that accepts arguments (it must accept all necessary arguments to fully initialize the Policy object).
• Include appropriate setters and getters (i.e., mutator and accessor methods) for each field.
• Include a method that calculates and returns the BMI of the policyholder.
○ BMI = (Policyholder's Weight * 703) / (Policyholder's Height²).

Answer 1

The Policy class models an insurance policy, including attributes like Policy Number, Policyholder's details, and physical characteristics. It features constructors, setters/getters, and a BMI calculation method for a comprehensive representation.

Step-by-step explanation:

In programming the Policy class, the goal is to represent an insurance policy comprehensively. The no-arg constructor ensures default values, while the parameterized constructor allows the creation of a policy with specified attributes. The inclusion of setters and getters enhances encapsulation, providing controlled access to class attributes.

The BMI calculation method facilitates the computation of the policyholder's BMI, a valuable health indicator. The formula incorporates the policyholder's weight in pounds, height in inches, and the constant 703.

This class design promotes code reusability and readability. It encapsulates policy-related data and operations within a single unit, following best practices in object-oriented programming. The BMI calculation adheres to the well-established formula, and the inclusion of setters and getters ensures proper data manipulation and retrieval. This approach aligns with software development principles, facilitating effective policy modeling and maintenance.
