the code above is just short and an overview i removed the declarations part because of text limits.
and

as you can see in the official invoice the only thing that will be printed is the cash invoice and the total.

i want to see the items that the user orders and be printed in the Official Invoice part and same as the quantity just like the official I.O of the MCDONALDS! thanks! and more power!

Welcome to the forum! Thanks for taking the time to learn how to post code correctly. If you haven't already, please read this topic to learn other useful info for new members.

Wow!

I assume the first 400 or so lines of code is the main() method. Correct? Most of the code in the main() method should be moved to other methods. You might have methods that get sandwiches, drinks, sides, meals, etc., each method doing one thing and one thing only, each with its own repeating, error handling, etc.

I doubt you'll take that advice, so to your original question, there is really only one solution: keep track of the items ordered and output them on the invoice. It's not clear what tools you can use to do that, but a String, a String array, or a StringBuilder object are possible choices in which to collect the items ordered. Since I think the String option might be the only tool in your box at the moment, it would work something like:

Item ordered: Hamburger Happy Meal with Extra Fat

// previously declared: String orderedString;
orderedString += "Hamburger Happy Meal with Extra Fat" + "\n";

repeating for each item ordered.

In this way, each item ordered is added to the orderedString object. Then when the invoice is printed, the orderedString object is output. Now, if you want to add the details like quantity and price after each item ordered in the orderedString object, that becomes more complicated, and the String approach might not work. It's a start.

I doubt you'll take that advice, so to your original question, there is really only one solution: keep track of the items ordered and output them on the invoice. It's not clear what tools you can use to do that, but a String, a String array, or a StringBuilder object are possible choices in which to collect the items ordered. Since I think the String option might be the only tool in your box at the moment, it would work something like:

Item ordered: Hamburger Happy Meal with Extra Fat

// previously declared: String orderedString;
orderedString += "Hamburger Happy Meal with Extra Fat" + "\n";

repeating for each item ordered.

In this way, each item ordered is added to the orderedString object. Then when the invoice is printed, the orderedString object is output. Now, if you want to add the details like quantity and price after each item ordered in the orderedString object, that becomes more complicated, and the String approach might not work. It's a start.

about the one with the quantity can you tell me i know you said that it can be more complicated but try me! haha! i dont get 1 for programming with just nothing! ^_^

There are of course more productive ways of achieving the same things
like using an array for example, but this is one of the most simplistic.

haha uhmm you dont get it! XD the problem is the quantity that will be displayed in invoice XD i do get the quantity for each of the items. i was just having a mental block this days that i cant think properly and deadline is coming near XD

thanks tho! (Y)

Then for the invoice to show how many of each product was sold
you could print the gathered variable value that represented the
quantity (and price for that matter) - in a similar manor to the
product description.

Apologises if this is still not what you meant.

unless i misinterpret you but what your saying is easy if you only have a hand countable items and you want all to be printed in the invoice but what if you only wanted to print are the things you ordered and you got hundreds of items in your menu? hope you get my point? XD

What would the textfile be needed for?

I am sorry, but to be honest, I still dont exactly understand what the problem is.
I see that you know how to print something to screen. And you seem to understand how variables work.
What exactly do you have problems with?

By the way, perhaps an OOP approach would be good for a task like this.

Then write a program that would interact with the text file and print
the menu to the screen. (Using file write and read algorithms).

The user could pick the items he/she wanted, and the quantity of the
items, and then have the program read from the file only the menu items selected by
the user and display them on the invoice, along with the quantity ordered
and their individual pricing, in the list format you specify.

ok so i guess that's way out of our lessons and i doubt i would need that tho thanks for your help i might study in advance for that

actually we are in OOP! >.< and anyways on what my problem is this:

in the code above my problem is showing what was ordered and how many did he/she ordered.
and so i managed to print what he/she ordered in the I.O part but i dont get how would I also include on how many items did he/she ordered for the specified item.
ex.
the user ordered FRIES FLOAT and SUNDAE the IO should have look like similar to this:

5 X REGULAR FRIES 125.00
2 X MC FLOAT 50.00
3 X SUNDAE 75.00
-----------------------------
total 250.00

i already got on how would i display the total price and the items ordered just displaying it's price and the quantity ordered per item.
hope you got my problem now >.<

The program does not look OOP in the slightest. The methods are static (completely against OOP paradigm) and all code is put into one huge method that does everything.

You said you know how to display the total price, but in order to calculate this price you should also know the quantities of the articles.
Total price should be something like:

totalPrice = 0;
 
for (Item in Buy-List) do
    totalPrice += Item.cost * Item.quantity;
end-for
 
return totalPrice

In this case I dont see what the problem is.

i know it was not yet in OOP approach we are still in the SA that's why. and anyways i dont understand why people dont get my point >.<
anyhow i'll try to solve my own problem XD

but i was just wondering and this is an off topic hope they allow this but.

how do you make java to clear the "windows console"? example:

enter input: 1

the user will input the "1" then after he/she hit's the enter the "enter input: 1" will be cleared and the console will display another list of outputs..

is that possible? if i remember it right it was possible in c# or c++ perhaps? the cls or clr command or a like? in java is that possible?

You have no control over the console, its a completey different and independent program.
In java its only a PrintStream. You can re-route the output to anything else, so clearing doesnt make sense.

What you can do is just print a bunch of empty lines if you like to push the old output back.
