Review the provided code for the Rewards Program. Identify at least five issues related to: Consistency and naming conventions. Code smells and maintainability. Logical correctness and future adaptability. For each issue: Explain the problem clearly. Propose a concrete improvement. Suggest one test case for the calcreward and one for gettype methods to ensure proper functionality. public class Rewardz { /** * Calculates the total amount after applying discounts based on item count and spending. * * @param t Total amount spent by the customer * @param i Number of items purchased * @return Adjusted total amount after discounts */ public double calcreward(double t, int i) { if (i > 5) { t = t – (t * 0.05); // 5% discount for more than 5 items } if (i > 15) { t = t – (t * 0.1); // 10% discount for more than 15 items } if (t > 200) { t = t – 20; // Flat $20 discount for spending over $200 } return t; } /** * Determines the customer’s reward tier based on spending history. * * @param p Number of purchases made * @param sp Total spending across all purchases * @return The customer reward tier as a string (“Gold”, “Silver”, “Bronze”) */ public String gettype(int p, double sp) { if (sp > 1000) { return “gold”; } else if (sp >= 500) { return “silver”; } else { return “bronze”; } } public void main(String[] args) { Rewardz r = new Rewardz(); double reward = r.calcreward(250, 10); System.out.println(“Total Reward: ” + reward); String custType = r.gettype(8, 750); System.out.println(“Customer Type: ” + custType); }}
