Question

JAVA. Create a UML class diagram for the following class/driver:

PhoneCaseSaleApp.java :

import java.util.Scanner;

public class PhoneCaseSaleApp

    public static void main(String args[])
    {
        int blue_count = 0, black_count = 0, rainbow_count = 0, tie_dye_count = 0, floral_delight_count = 0;
        int hard_count,gel_count;
        float hard_cost, gel_cost;
        float hard_profit, gel_profit;
        float total_cost;
        float total_profit;
        Scanner in = new Scanner(System.in);
        System.out.println("How many Blue Hard Cases to Order");
        blue_count=in.nextInt();

        gel_count = rainbow_count+tie_dye_count+floral_delight_count;
        System.out.println("Total Gel Cases Sold = " +gel_count);
      
        HardCaseSale h = new HardCaseSale(blue_count,black_count);
        GelCaseSale g = new GelCaseSale(rainbow_count, tie_dye_count, floral_delight_count);
        System.out.println("Order Summary");
   System.out.println();
   System.out.println();
        h.toString();
   System.out.println();
   System.out.println();
        g.toString();
   System.out.println();
   System.out.println();
        hard_cost = h.calculateHardCaseCost();
        gel_cost = g.calculateGelCaseCost();
        hard_profit = calculateHardCaseScoutProfit(hard_count, hard_cost);
        gel_profit = calculateGelCaseScoutProfit(gel_count, gel_cost);
   System.out.println("Profit from Hard Cases= "+hard_profit);
   System.out.println("Profit from Gel Cases= "+gel_profit);
        total_cost = hard_cost + gel_cost;
        total_profit = hard_profit + gel_profit;
        calculateTotalNetCost(total_cost, total_profit);
      
    }
    public static float calculateHardCaseScoutProfit(int count, float cost)
    {
        float r;
        float p;
        if(count > 9)
        r = 12.0f;
        else
        r = 7.0f;
        p = cost*(r/100);
        return p;
      
    }
     public static float calculateGelCaseScoutProfit(int count, float cost)
    {
       float r;
        float p;
        if(count > 7)
        r = 12.0f;
        else
        r = 7.0f;

        return p;
      
    }
    public static void calculateTotalNetCost(float total_cost, float total_profit)
    {

        float netCost = total_cost - total_profit;
        System.out.println("Total Net Cost = "+netCost);
    }
}
