how to continue the loop inside the if else case?

Question

final static int arrayLength = 1000; //maximum array size
    static float[] productPrice = new float[arrayLength]; //stores the prices of products
    static String[] productName = new String[arrayLength]; //stores the names of products

    public static void main(String[] args) {

        boolean quit = false;
        do {
            System.out.print("enter product: ");
            String product = keyboard.nextLine();;
            for(int i=0; i<productName.length; i++)
                productName[i] = product;

            System.out.print("enter price: ");
            float price = keyboard.nextFloat();
            for(int i=0; i<productPrice.length; i++)
                productPrice[i] = price;

            if(price == -1)
                quit = true;
        } while(!quit);

        for(int i=0; i<productPrice.length; i++)
            if(productPrice[i] > productPrice[i+1]) {
                float temp = productPrice[i+1];
                productPrice[i+1] = productPrice[i];
                productPrice[i] = temp;
                System.out.println("Product: " + productName[i] + "\nPrice: " + productPrice[i]);
            }
    }

do while is the statement you are looking for

check out the updated code with do while there. but the problem 'continue loop until i press -1' is still not working. any suggestions? – May 01 '13 at 15:02
looks like it is not so easy to compare float numbers: http://stackoverflow.com/questions/10334688/how-dangerous-is-it-to-compare-floating-point-values – Delcasda May 01 '13 at 15:25

Price is declared as a float and you're comparing it to an int. Try:

if((int)price == 1)

or

if(price == 1.0f)
