question about for loop

[Ray Friedrich]

this program makes a user input how many shipments should be shipped which is (s)
then reads the array of 4 and I want to know how can I put this system.out
System.out.print("L: ")
System.out.print("M: ")
System.out.print("S: ")

s is the number of shipping loop. sorry if this is already in the boards. thank you for your kind consideration.

for( int s = 1; s < iNum+1; s++)
        {
            System.out.print("\nShipment #"+ s +" - "+ sCompanyName);
                           for(int t = 0; t < amount.length; t++)
            {
                System.out.print("\XL: ");
                amount[t]= input.nextLine();

            }

        }

Welcome to JavaRanch, Ray.

A few things:
1. When posting code, please UseCodeTags (←click). I've added them for you this time - see how much better it looks?
Also: avoid long lines, especially when you have comments, because they make your thread difficult to read.

2. Try to avoid using cryptic names. You've had to explain that 'bName' == company name, whereas if you'd called it 'companyName' it would be self-explanatory.

3. I presume you want to print a different 'size' ("XL", "L" etc) when you go through you loop. How about storing those strings in an array? (sizeString?)

Welcome again

Even though you see it in many books, you should not use \n unless somebody says they want LF. Brief explanation and a suggestion about what to use instead here. I suspect you do not actually want a new line there; the user will have pushed enter after the previous input.

sorry mods, I edited it and if there is something else that needs to be edit let me know,
so how do I do the sizeString? thank you.

 
String[] as_ShipmentSize = new String[4];

       as_ShipmentSize[0] = "XL: ";

       as_ShipmentSize[1] = "L :";

       as_ShipmentSize[2] = "M: ";

       as_ShipmentSize[3] = "S: ";

like this?
if yes how can I make the user ask this questions?

Your code can be shortened to:

String[] as_ShipmentSize = {"XL: ", "L: ", "M: ", "S: "};

I don't understand your question:

And please do not ask questions inside code tag .

[Ray Friedrich]

ok I edited it thank you for telling me, so how can I ask those 4 questions inside a for loop which depends on the number of shipments?

[Campbell Ritchie]

Sounds as though you want a Shipment class, which encapsulates the size and the number of items. You can iterate the array printing the sizes and asking for the amount. Consider whether you want a setSize method (I think no) and a setAmount method (I think yes).
Find out about using an enum for the sizes.

Please check the naming conventions; I think the as_ bit should be removed from the name of your array. Don't double‑space your code; use single blank lines to separate it into sections.

hello guys, I am almost done with my assignment and would like to know if its ok if I post the whole code here because I dont know how to calculate the sum of the arrray that was converted using arithmetic equation.

[Campbell Ritchie]

Yes, of course it is, as long as your teachers have no problem with posting code publicly.

[Ray Friedrich]

yes he doesnt care as long as we pass

the program wants to calculate the total for XL , the total for Large, total for Medium and total for Small
and I posted the last part of the requirements. thanks sirs and mams
