Question

In JAVA, we are to create a class

A uml diagram that helps with the Java coding process:

Write your own version of a generic class named MyQueue that will create a static queue of any data type. Submit only the class itself, do not include a driver program. I will import your class into my own driver program and test it myself as part of grading. Be sure to include the following methods: ??Constructor ? accepts an integer argument specifying the length of the queue. ??enqueue ? Accepts a value to put in the queue. Throws an exception if the queue is full. ?-.dequeue ? Returns a value from the queue. Throws an exception if the queue is empty. ??isFull ? Returns true if the queue is full, false otherwise. ??isEmpty - Returns true if the queue is empty, false otherwise. ??toString ? Returns a string representation of the queue. You may not use the Java API queue container(java.util.Queue). For the exception, Just throw an Exception, i.e., new Exception(Something)

Explanation / Answer

public class MyQueue<E> implements Queue<E> {
    private Object[] container;
    private int startOfQueueIndex;
    private int numberOfElements;

    public MyQueue(int size) {
        container = new Object(size);
        startOfQueueIndex = 0;
        numberOfElements = 0;
    }

    public boolean enqueue(E e) {
        if (container.IsFull()) throw new java.lang.IllegalStateException: Queue full();
          else

       container[(startOfQueueIndex + numberOfElements++) %container .length] = e;
    }

    public E deqeue() {
        if (container.IsEmpty())
            throw new new java.lang.IllegalStateException: Queue empty();
      else
        E contain = (E)container[startOfQueueIndex];
       startOfQueueIndex = (startOfQueueIndex + 1) %container .length;
      return contain ;
    }
public boolean IsFull()
{
   if(container.length==size)
    return 1;
else
   return 0;
}
public boolean IsEmpty()
{
if(container.length==0)
    return 1;
else
   return 0;
}
String toString(E q)
   {
       String str=q.toString();
     return str;
   }

   }
