                case 2:
                System.out.println();
                ctr2=1;
                System.out.println("Select products and add to cart");
                for(ctr=0;ctr<nList;ctr++)
                {
                    System.out.println(ctr2 + ". " + itemArray[ctr] + " " + priceArray[ctr]);
                    ctr2++;
                }
                System.out.println();
                System.out.println("Enter the number of item you want to purchase: ");
                int itemPur = Integer.parseInt(a.readLine());
                System.out.println("Choose the product you want to add to cart");
                for(ctr1=0;ctr1<itemPur;ctr1++)
                {
                    System.out.println("Enter your choice: ");
                    choice1=a.readLine();
                    for(ctr=0;ctr<itemPur;ctr++)
                    {
                        if(choice1.equalsIgnoreCase(itemArray[ctr]))
                        cartArray[ctr1]=choice1;
                        ctr1++;
                    }
                }

is this code right for storing choices?

                for(ctr1=0;ctr1<itemPur;ctr1++)
                {
                    System.out.println(cartArray[ctr1] + " " + priceArray[ctr1]);
                    double totalPur = 0;
                    totalPur = totalPur + priceArray[ctr1];
                }
                System.out.println("Your total cost is " + totalPur);
                ctr2=ctr2-ctr2;
                break;

Why does my variable "totalPur" is not recognize if i build the file..
this is just a continuation of the upper part code..

[JamesCherrill]

You declare totalPur inside the loop, so you get a brand new totalPur each time thru the loop and the previous one(s) are forgotten. Declare and initialise it before you enter the loop so the same variable is used throughout.

You'll have to explain exactly how the output differs from what you wanted.

what i want to get is that after i enter the product i want to add to cart.. it will show the item's you added to cart and tells the total amount to be paid..
