Problem in writing method by reading a text file

Hi. i have a program to write which is as follow.
Ma and Pa need a program that will project the profit of their
sporting goods department. the items in the department are with a 1,2
or 3 depending on the amounf of profit for the item. An item with a
profit code of 1 produces a 10 percent profit, a code of 2 produces a
12 percent profit and a code of 3 generates a 15 percent profit. write
a program that will project the profit of the following inventory.
Item quantity price Profit code
Fishing_Line 132 3.95 1
Fish_hooks 97 0.89 2
Snikers 123 0.49 2
Fish_nets 12 8.75 1
Spinner_Baits 256 2.49 3
Jigs 49 0.29 3

The program should generate a report of the item, quanity, expected
profit in dollars per item, and total expected profit for all items.
You are required to divide the whole program into several functions.
for example readDataFile, computation and write results..

ok i have done the first part yet which reads the file and output on
the screen. what i was trying to do is read just the item name which
is(fishing_line) and the quantity(3.95). once this is printed i could
have write methods of calculating profit per item and profit for all
items. so i created array of string but for some reason it prints the
whole file which includes int also. my second question is when i will
write a method what parameters do i need to pass to it so it
calculates the profit per item and for all items based on my txt file.
i can't make any sense out of it . please direct me on the rite track
i appreciate that.

class ProfitCalculator
{
    public static void main(String[] args) throws IOException
    {
        Scanner s = null;
            ProfitTester test = new ProfitTester();
        String[] name = new String[100];
        int[] number = new int[100];
        double quantity;
        try
        {
            s = new Scanner(
                new BufferedReader (new FileReader("saloo.txt")));
                for (int i=0; i<name.length; i++)
                        {
                while(s.hasNext())
                {
                    if(s.hasNext())
                    {

                        name[i] = s.nextLine();
                        System.out.println(" " + name[i].trim());
                    }
                    }

                }
        }
        finally
        {
            s.close();
        }
        }
}

how can i write method like calculating profit per item and for all
the items?. or my question is how can i pass the first item which is
fishing_line and its price and quantity to my method? what parameters
i need to use. please dont start pounding at me. i am good in java but
not good when it comes to read file and output the data etc.. any help
will be appreciated.
