Please help How to implement Queue in java ?

Akash Rajgure

Implement the array-based Queue in Java assuming the interface is already given in Queue.Java Training. Write a main method to have a Queue with the following operations :

1. enqueue(5); 2. enqueue(3); 3. dequeue();

**Queue.java:

public interface Queue {

/**

* Returns the number of elements in the queue.

* @return number of elements in the queue.

*/

public int size();

/**

* Returns whether the queue is empty.

* @return true if the queue is empty, false otherwise.

*/

public boolean isEmpty();

/**

* Inspects the element at the front of the queue.

* @return element at the front of the queue.

* @exception EmptyQueueException if the queue is empty.

*/

public Object front() throws Exception;

/**

* Inserts an element at the rear of the queue.

* @param element new element to be inserted.

*/

public void enqueue (Object element)throws Exception;

/**

* Removes the element at the front of the queue.

* @return element removed.

* @exception EmptyQueueException if the queue is empty.

*/

public Object dequeue() throws Exception;

}
