By comparing the output in Example 6.1 with that of Example 5.1 on page 103, it is easy to see that the only operational difference between a queue and a stack is the access point. With a queue, it is at the front, where the oldest element the one that has been there the longest is found. With a stack, it is at the top, where the youngest element the one that arrived most recently is found. Notice that for the ArrayDeque class, the toString() method (invoked automatically by the println() method at line 8) displays the queue from front to back, and the stack from top to bottom. So in both cases, the access point is at the left end of the display. A SIMPLE Queue INTERFACE The operational requirements of a queue can be formalized by this simple Java interface: EXAMPLE 6.2 A Queue Interface

Painting Linear 1D Barcode In C#
Using Barcode creation for Visual Studio .NET Control to generate, create 1D image in Visual Studio .NET applications.
In addition to the three required queue operations, this interface also specifies an isEmpty() method and a size() method.
Compare the Queue interface shown in Example 6.2 with the JCF s Queue interface, shown in Figure 4.10 on page 89. It includes offer(), peek(), and poll() methods. In most situations, these are the same operations as the add(), element(), and remove() methods, respectively. If a limited-capacity queue is full, the add() method throws an IllegalStateException, while the offer() method merely returns false. If the queue is empty, the element() the remove() methods throw a NoSuchElementException, while the peek() and poll() methods merely returns null.

AN INDEXED IMPLEMENTATION
QUEUES
Like stacks and other linear data structures, queues can be implemented using an ordinary array. The ArrayQueue class shown in Example 6.3 is similar to the ArrayStack class shown in Example 5.3 on page 104. EXAMPLE 6.3 An ArrayQueue Implementation

public class ArrayQueue<E> implements Queue<E> { private E[] elements; private int front; private int back; private static final int INITIAL_CAPACITY = 4; public ArrayQueue() { elements = (E[]) new Object[INITIAL_CAPACITY]; } public ArrayQueue(int capacity) { elements = (E[]) new Object[capacity]; } public void add(E element) { if (size() == elements.length - 1) { resize(); } elements[back] = element; if (back < elements.length - 1) { ++back; } else { back = 0; //wrap } } public E element() { if (size() == 0) { throw new java.util.NoSuchElementException(); } return elements[front]; } public boolean isEmpty() { return (size() == 0); } public E remove() { if (size() == 0) { throw new java.util.NoSuchElementException(); } E element = elements[front]; elements[front] = null; ++front; if (front == back) { // queue is empty front = back = 0; }
QUEUES
if (front == elements.length) { front = 0; } return element; } public int size() { if (front <= back) { return back - front; } else { return back - front + elements.length; } } private void resize() { int size = size(); int len = elements.length; assert size == len; Object[] a = new Object[2*len]; System.arraycopy(elements, front, a, 0, len - front); System.arraycopy(elements, 0, a, len - front, back); elements = (E[])a; front = 0; back = size; } } // wrap
