I understand the guidelines but i do not know where to start. If someone could help me even set up this program i would appreciate it. Thank you for your time.

Do you have any of your code started? The reason why I ask, is because the way your instructor wrote these directions, this isn't your first program. You should know how to start the progam, declare your constants and variables, use your import statements and so forth...

Instead of wasting your time trying to use the BBCode to make, unsuccessfully, a nice looking post, you should poke around in this forum looking the thousand of available exemples (may be not with fancy features) but with code... after all we are at Dream In Code

Tai Pan, he doesn't have any code to try and use BBCode....

00musdan, Perfect example... Most people who don't see you following the rules, just skip right threw post....

Ahhh, I see, lmao...got ya!

[00musdan]

sorry guys im a big noob. heres what i have so far. Thank you for your help ahead of time because a lot of people have done nothing but yell at me for my previous post. This part is for the cash register of the project as outlined above.

 package cashregister;

public class CashRegister {
	public CashRegister(double purchase, double payment){
		purch=purchase;
		pmt=payment;

		double giveChange(double price, double pmt){
			double change = pmt-price;
			return pay;
		}
	}

}

Good you made an effort
Here to put you on the right track

// forget the package statement for now
public class CashRegister {
	
	// the amount in the cash register
	double amount;
	
	// a constructor to build a new CashRegister
	CashRegister(double amount) {
		this.amount = amount;
	}

	// a method to accept cash which return the change
	double pay(double payment, double purchase) {
		System.out.println("For a purchase of $ " + purchase + " I received $" + payment);
		double change = payment - purchase;
		amount += purchase;
		System.out.println("Now I have $" + amount + " in my cash register");
		return change;
	}
	
	// the method to test the whole thing
	public static void main(String[] args) {
		// build a new CashRegister with $ 1000.00
		CashRegister cr = new CashRegister(1000.0);
		double change = cr.pay(100.00, 55.55);
		System.out.println("I received $" + change + " as change");
		
		
	}
}

Nobody was yelling at you.... There are alot of people who don't or won't put in any effort of their own, and expect other people to do the work for them. We just like to see some effort put it by you. Basically, take your time to try and figure out even the outline to your problem, and then post... Don't just post. BTW, pbl is an expert and a very helpful individual, and he should be respected as such...not to forget to mention a lot of others because they are all great as well. You seen what you wrote, and you get a very nice and detailed response...

ok thanks pbl i guess this is why ur the master. So i understand the code you wrote but should i make a currency class and declare pennies, nickels, dimes....etc? Because the whole program is supposed to act like a store where people select items and purchase them and the program gives them change, taxes items etc. I guess im just having a hard time planning this whole thing out.

[00musdan]

hey guys ok so i tried making a inventory class and a tester class but im getting all kinds of errors that i cant fix. maybe you guys will understand the problem.

public class StoreInventory
{
   
	RetailItem inventory[] = new RetailItem[10];

   
	public String addToInventory(RetailItem item)
	{
		for (int i = 0; i < inventory.length; i++) {
			// Look for empty spot and put the item there.
			if (inventory[i] == null) {
				inventory[i] = item;
								break;
						}
		}

		return "Done";  
	}

  
	public double getTotalPriceOfInventory()
	{
		double totalprice = 0.0;
		for (RetailItem currentItem : inventory) {
			if (currentItem != null) {
				totalprice += currentItem.getPrice();
			}
		}
		return totalprice;
	}

   
	public int getUnitsOnHand()
	{
		int unitsonHand = 0;
		for (RetailItem currentItem : inventory) {
			if (currentItem != null) {
				unitsonHand += currentItem.getUnitsOnHand();
			}
		}
		return unitsonHand;
	}

}

}

And for my tester program....

public class Tester {

	public static void main(String args[]) {
		StoreInventory inventory = new StoreInventory();

		RetailItem item = new RetailItem("jacket", 1, 23.00);

		inventory.addToInventory(item);

		Double total = inventory.getTotalPriceOfInventory();

		System.out.println(total.toString());
	}
}

I think im doing something wrong with trying to get all my classes to "talk" (tester, inventory, cash register)

[theautokustomizer]

I don't see any of your methods for item, and the parameters that you have in your tester go off of them...

As far as your money goes, I would declare my pennies,nickels, etc in another method...

EDIT: And if you have more code, let us see it...

What i have submitted is all i have... well the inventory, tester, and cash register. I think the problem is i dont have the all the right methods and i dont know how to include the cash register class pbl fixed earlier. I will try to start a currency class to declare the money as you suggested. THANKS FOR HELPING
