How do  I create a SALE object and save to the SALE object for the following method?
private void makeSale() {
		// menu item #6
		Scanner scan = new Scanner(System.in);
		displayCustomer();
		System.out.println("Are you a retail or wholsale customer?:  ");
		int cust = scan.nextInt();
 
		displayInventory();
		System.out.println("What item do you want to buy by number? ");
		int num = scan.nextInt();
 
		System.out.println("There are " + inventory.get(num).getNuminStock()
				+ " of these items for sale");
 
		System.out.println("How many of these items do you want to buy? ");
		int numSale = scan.nextInt();
 
		if (numSale > inventory.get(num).getNuminStock()) {
			System.out.println("There are only "
					+ inventory.get(num).getNuminStock()
					+ " of these items for sale");
			numSale = inventory.get(num).getNuminStock();
 
			if (customer.get(cust).getType().equalsIgnoreCase("retail")) {
				if (inventory.get(num).calculateInventoryValue() > 200) {
					System.out
							.println("\nBecause you ordered more then $200 worth of plants "
									+ "\nand are a retail customer "
									+ "\n You get a discount of:  "
									+ (inventory.get(num)
											.calculateInventoryValue() * .05)
									+ " dollars");
				}
			} else {
				double wholeValue = inventory.get(num)
						.calculateInventoryValue();
				System.out.println("\nBecause you are a wholesale customer "
						+ "\n You get a discount of:  " + wholeValue
						* customer.get(cust).getDiscountPercent() + " dollars");
 
			}
 
		}
 
		Inventory a = inventory.get(num);
		int temp = a.getNuminStock() - numSale;
		a.setNuminStock(temp);

What you need is to create a class called Sale with variables you need to "save" (cust, num, numscale). You need to create an instance of that Sale and put your data in the variable. The instance needs to be the same for this method and the next one.
How to do this depends on where the methods are located.

I also noticed that it seems you are doing this already with the inventory in your code: inventory.get(num).getNuminStock()
It is created somewhere and you get the data in this method now.

Hope this helps.
