Question

This needs to be coded in Java. Using nothing more complex than methods/loops/arrays.

Instructions You work for a paint shop and have been tasked with writing a program to calculate the cost of paint purchased. Prompt the user for the number of paint orders. Do not accept 0 or less for the number of paint orders. Prompt the user for the number of gallons of paint purchased for each order. Each gallon of paint costs $19.99. Do not accept 0 or less for the number of gallons .Calculate the cost of each order. Store the cost of each order in an array. Display the price of each order . Use a Selection sort algorithm to sort the order prices in the array from smallest to largest Display the sorted orders. Display the total price of all orders. Note: You will not read a file in this project. All code should be coded in the Main method Sample Input Enter the number of paint orders to process: 5 Enter the number of gallons for order 1: 3 Enter the number of gallons for order 2:7 Enter the number of gallons for order 3: 4 Enter the number of gallons for order 4: 2 Enter the number of gallons for order 51 Sample Output Smallest to largest orders: $19.99 $39.98 $59.97 $79.96 $139.93 The total cost of all paint orders is: $339.83

Explanation / Answer

PaintOrders.java

import java.util.Scanner;

public class PaintOrders {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter the number of paint orders to process: ");

int n = scan.nextInt();

int orders[] = new int[n];

double prices[] = new double[n];

for(int i=0;i<n;i++) {

System.out.println("Enter the number of gallons for order "+(i+1)+": ");

orders[i] = scan.nextInt();

if(orders[i] <= 0) {

System.out.print("Invalid Input.");

i--;

}

}

for(int i=0;i<n;i++) {

prices[i] = orders[i] * 19.99;

}

selectionSort(prices);

double total = 0;

System.out.println("Small to Large Orders: ");

for(int i=0;i<n;i++) {

total += prices[i];

System.out.printf("$%.2f ",prices[i]);

}

System.out.printf("The total cost of all paint orders is: $%.2f ",total);

}

public static void selectionSort(double prices[]){

for (int i = 0; i < prices.length - 1; i++)

{

int index = i;

for (int j = i + 1; j < prices.length; j++)

if (prices[j] < prices[index])

index = j;

  

double smallerNumber = prices[index];

prices[index] = prices[i];

prices[i] = smallerNumber;

}

}

}

Output:

Enter the number of paint orders to process:
5
Enter the number of gallons for order 1:
3
Enter the number of gallons for order 2:
7
Enter the number of gallons for order 3:
4
Enter the number of gallons for order 4:
2
Enter the number of gallons for order 5:
1
Small to Large Orders:
$19.99
$39.98
$59.97
$79.96
$139.93
The total cost of all paint orders is: $339.83
