Restricted access containers provided encapsulated storage of information for algorithms where the storage is decoupled from the details of insertion and removal of data from the storage.

Introduction

Stacks and queues are examples of containers with special insertion and removal behaviors and a special access behavior.

Insertion and removal in a stack must be carried out in such a way that the last data inserted is the first one to be removed.  One can only retrieve and remove a data element from a stack by way of special access point called the "top".  Traditionally, the insertion and removal methods for a stack are called push and pop, respectively. push inserts a data element at the top of the stack. pop removes and returns the data element at the top of the stack. A stack is used to model systems that exhibit LIFO (Last In First Out) insert/removal behavior. 

Data insertion and removal in a queue must be carried out in such a way that the first one to be inserted is the first one to be removed.  One can only retrieve and remove a data element from a queue by way of special access point called the "front". Traditionally, the insertion and removal methods for a queue are called enqueue and dequeue , respectively. enqueue inserts a data element at the "end" of the queue. dequeue removes and returns the data element at the front of the queue. A queue is used to model systems that exhibit FIFO (First In First Out) insertion/removal behavior. For example, one can model a movie ticket line by a queue.

We abstract the behaviors of special containers such as stacks and queues into an interface called IRAContainer specified as follows.

Restricted access containers

Iracontainer.java

package rac; import listFW.*;/** * Defines the interface for a restricted access container.*/ public interface IRAContainer {/** * Empty the container.* NOTE: This implies a state change. * This behavior can be achieved by repeatedly removing elements from this IRAContainer.* It is specified here as a convenience to the client. */public void clear(); /*** Return TRUE if the container is empty; otherwise, return * FALSE.*/ public boolean isEmpty();/** * Return TRUE if the container is full; otherwise, return* FALSE. */public boolean isFull(); /*** Return an immutable list of all elements in the container. * @param fact for manufacturing an IList.*/ public IList elements(IListFactory fact);/** * Remove the next item from the container and return it.* NOTE: This implies a state change. * @throw an Exception if this IRAContainer is empty.*/ public Object get();/** * Add an item to the container.* NOTE: This implies a state change. * @param input the Object to be added to this IRAContainer.* @throw an Exception if this IRAContainer is full. */public void put(Object input); /*** Return the next element in this IRAContainer withour removing it. * @throw an Exception if this IRAContainer is empty.*/ public Object peek();}

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
