Insurance Premium Calculator

Introduction

In this exercise, we'd like to understand your problem-solving abilities and collaboration skills. It's essential that you communicate effectively, ask clarifying questions as needed, and notify us of any simplifications you'd like to make outside the provided requirements.

NOTE: We do not necessarily expect you to complete the entire exercise; instead, we're interested in observing your progress and understanding the approach you take.

Scenario

You are tasked with developing a calculator for a company that needs to compute the cost of home insurance premiums, referred to as homePremium. The homePremium is determined based on number of bedrooms, customer's age and credit score.

Requirements

These are applied in order

1. The base homePremium for any home is £100 per bedroom.
2. If the customer is over 60 years old, the base homePremium of the home should increase by 20%.
3. If the customer's credit score is below 600, the homePremium increases by 15%.

Examples

Name	Date of Birth	Credit Score	Home Built	Home Number of Bedrooms	Premium Price
Justin Case	20/05/1990	900	1990	2	200
Sherlock Homes	04/03/1957	700	1940	4	480
Polly C. Holder	11/12/1930	550	1930	4	552

Inputs

A customer profile that includes:

• Customer's name
• Customer's date of birth
• Customer's credit score
• Year the home was built
• Number of bedrooms in the home

Output

The price of the insurance policy, expressed as a number with up to 2 decimal places. No currency is specified.

Simplifications

• Ignore any currency concerns.

Instructions

• Develop the above requirements in a way that reflects your typical development process.
• You can modify any existing code except for the output code using println(), which is deemed adequate as the output mechanism. The remaining code serves as a guideline for your implementation.
• Feel free to add, modify, or delete classes as needed for your implementation. Here's a summary of the existing classes:
  • Main: Outputs the calculated premiums.
  • HomePremium: Manages the calculation of the premium.
  • CustomerProfile: Contains all necessary details for premium calculation.
• Your objective is to build a solution that is verifiable and extensible.

Possible Future Requirement

4. An additional £20 premium will be added for each decade (10 years) that the home is older than 1980.
