The code below about RandomizedQueue when I test it it jsut show the last element add. Any help to fix that to show all element that "enqueue" in RandomizedQueue

public class RandomizedQueue implements Iterable {

public static void main(String[] args) {

}

public int count=0;

private Item[]list;

@Override

public Iterator iterator() {

// TODO Auto-generated method stub

return new RandomizedQueueIterator<>();

}

// construct an empty randomized

public RandomizedQueue() {

list=(Item[])new Object[1];

}

// is the randomized queue empty?

public boolean isEmpty() {

return count==0;

}

// return the number of items on the randomized queue

public int size() {

return count;

}

// add the item

public void enqueue(Item item) {

if (item == null)

throw new NullPointerException();

if (list.length <= count)

resize(count * 2);

list[count++] = item;

}

private void resize(int i) {

// TODO Auto-generated method stub

Item[] temp = (Item[]) new Object[i];

for (int j = 0; i < list.length; i++) {

temp[j] = list[j];

}

list = temp;

}

// remove and return a random item

public Item dequeue() {

if (count == 0)

throw new NoSuchElementException();

int i = StdRandom.uniform(count);

Item x = list[i];

list[i] = list[count - 1];

list[count - 1] = null;

count = count - 1;

return x;

}

// return a random item (but do not remove it)

public Item sample() {

if (count == 0)

throw new NoSuchElementException();

int randomItemIndex = StdRandom.uniform(count);

return list[randomItemIndex];

}

private class RandomizedQueueIterator implements Iterator {

private int value;

private int[]list_value= new int[count];

@Override

public boolean hasNext() {

return value

}

@Override

public Item next() {

if(!hasNext())

throw new NoSuchElementException();

return (Item) list[list_value[value++]];

}

}

}

Here the test:

public class RandomizedQueueTest {

public static void main(String[] args) {

RandomizedQueue rq = new RandomizedQueue();

System.out.println("Test Deque");

rq.enqueue("A");

rq.enqueue("B");

rq.enqueue("C");

assert rq.size() == 3;

for (int i = 0; i < 3; i++) {

System.out.println(rq.dequeue());

}

}

}

Return:

Test Deque

C

null

null
