This is what my code is suppose to do:
Create an array of FIVE (5) RetailItem objects.
Read in data for the 5 RetailItem objects. After all data has been read in, use another loop to calculate the total price of the inventory. The total price of the inventory is calculated by adding the price * unitsOnHand for each item.

Sample Output:
Enter Units On Hand, Price and Description:
1: 10 5.00 pencil
2: 3 10.25 pen
3: 5 2.25 spoon
4: 12 11.15 book
5: 10 532 tv

Totals:
PENCIL: $50.00
PEN: $30.75 SPOON: $11.25
BOOK: $133.80
TV: $5,320.00
Total Inventory: $5,545.80

I have created this code here:

import java.util.Scanner;
public class Demo
{
public static void main(String []args)
{
Scanner keyboard =new Scanner(System.in);
int numItems = 0;
String description[];
description[] des = new description[numItems];
int unitsOnHand[];
unitsOnHand[] units = new unitsOnHand[numItems];
double price[];
price[] p = new price[numItems];
double totalPrice = 0;


System.out.print("Enter the number of items: ");
numItems = keyboard.nextInt();
//RetailItem item = new RetailItem(description, unitsOnHand, price);
RetailItem[] items = new RetailItem[numItems + 1];

System.out.println("Enter Units On Hand, Price and Description:");
for(int i=1; i<items.length; i++)
{
System.out.print(i + ": ");
unitsOnHand[i] = keyboard.nextInt();
price[i] = keyboard.nextDouble();
description[i] = keyboard.nextLine();
items[i] = new RetailItem(description[i], unitsOnHand[i], price[i]);

totalPrice = totalPrice + (price[i]*unitsOnHand[i]);
}
System.out.println("Totals:");
for(int i=1; i<items.length; i++)
{
System.out.println(description[i] + ": " + unitsOnHand[i]*price[i]);
}
System.out.println("Total Inventory: " + totalPrice);
}
}

And I keep getting errors no matter how I change it up! Currently I have these errors:

Demo.java:9: cannot find symbol
symbol : class description
location: class Demo
description[] des = new description[numItems];
^

These are syntax errors that are being generated by your improper use of arrays.

Check out some Java array tutorials and sample code:

Thanks so much for the tutorial link! It really helped me with my array confusions!
