    Default Help with queue array please!!

    Could someone please point me in the right direction. I am creating a queue array of customers. I have highlighted the code I am having problems with when trying to intalize the Queue, really cant get around this, any help?



    class QueueCustomer{
    final int MAXSIZE=5;
    Customer queue[] = Customer [MAXSIZE];// Array called queue. Can store up to 5 customers
    int qhead;
    int qtail;
    int qnoElements;

    //Construct the queue
    QueueCustomer(){
    for(Customer tmpCustomer:queue)
    tmpCustomer = ' ';

    qhead = 0; /* head initialised to 0 to point to start of queue.*/
    qtail = -1; /* tail initialised to -1 as the is no end of queue.*/
    qnoElements = 0; /* noElements initialised to 0-No elements on queue.*/
    }

    Check out the third–from–last sentence, "Similarly it is not ...", at the bottom of this page in the javadocs guide The For-Each Loop.
    Java Code:
    public class Test {
        public static void main(String[] args) {
            String[] strs = new String[5];
            int count = 0;
            for(String s : strs) {
                System.out.println("count = " + count++);
                s = "alfred e neuman";
            }
            for(String s : strs)
                System.out.println(s);
            System.out.println("----------------");
            for(int j =0; j < strs.length; j++)
                strs[j] = "tally ho";
            for(String s : strs)
                System.out.println(s);
        }
    }
