** and here is my actual lab that i need to work with and fix somemore.


import java.util.Random;
import java.util.Scanner;

public class GenCheeseShopv2 {

    public static void intro(String[] names,double[]prices, int[] amounts) {
        // Fill-in
    }

    public static void getAmount(Scanner input,String[] names, int[] amounts) {
        // Fill-in
    }

    public static void itemizedList(String[] names,double[]prices, int[] amounts) {
        // Fill-in
    }

    public static double calcSubTotal(double[]prices, int[] amounts) {
        // Fix
        return 0;
    }

    public static int discount(double subTotal){
        // Fix
        return 0;
    }

    public static void printTotal(double subTotal,int discount) {
        // Fill-in

    }

    public static void main(String[] args) {

        final int MAXCHEESE = 4;

        // DO NOT CHANGE ANYTHINGBELOW
        String[] names = newString[MAXCHEESE];
        double[] prices = newdouble[MAXCHEESE];
        int[] amounts = newint[MAXCHEESE];

        Scanner input = newScanner(System.in);

        intro(names, prices,amounts);

        getAmount(input, names,amounts);

        double total =calcSubTotal(prices, amounts);
       
        if (MAXCHEESE > 0) {
           System.out.print("Display the itemized list? (1 for yes) ");
            intitemized = input.nextInt();

            if(itemized == 1) {
               itemizedList(names, prices, amounts);
            }
        }

        System.out.println();

       printTotal(total,discount(total));
    }
}

Explanation / Answer

publicstatic double calcSubTotal(double[] prices,int[] amounts){

double subTotal = 0;

for (int i=0;i<prices.length;i++)

{

subTotal = subTotal + (prices[i]*amounts[i]);

}

return subTotal;

}

publicstatic intdiscount(doublesubTotal){

// Fix

return 0;

}

publicstatic voidprintTotal(double subTotal,int discount){

System.out.println("Sub Total: $" +subTotal);

System.out.println("-Discount: $" +discount);

double total = subTotal - discount;

System.out.println("Total : $" +total);
