In today's world, the electronic version of the above can be sent as an ecard via any standard email service provider instantly over the internet.
How can the sender and receiver achieve the above?In order for the above to be possible today, the sender must have have an electronic mail address which is referenced to a domain name. The same goes to the receiver.
It is to be noted that the data (in this case the text and pictures contained int he postcard) are delivered to user accounts across several computer servers.
The computer servers transport the messages to their final destination and store them so that users may retrieve and send them whenever they connect to the email infrastructure. An email client or a web interface can be used to access email.
What are the comparisons?While there is a feeling that comes with handling physical mail such as the advantage of having the card retrieved without electricity, the ability to create handcrafted art, and even perfumed cards, they took relatively too long to prepare and to be sent to receiver.
Unlike traditional mail, electronic postcards are can be created, customized and sent withing a minute. E-post cards, unlike traditional ones, can be automated and sent to million of people at the same time in an instant.

Ok then..lol What does that even mean?
Suppose that you have created a program with only the following variables
Int age=34
Int weight =180
Double height =5.9
Suppose that you also have a method with the following header:
Public static void calculate (Int age, double size)
Which of the following methods calls are legal and why
Calculate (age, height)
Calculate (weight, weight)
Answers
Explanation:
Calculate (age, height) is legal because method's second argument (double size), needs double value.
what coder does assembly language use for programming?
Answers
Answer:
These short codes are converted into machine learning language (binary, i.e., 1s and 0s) through the use of programs called assemblers. In a nutshell, machine language uses binary code, which is almost impossible for humans to decipher, whereas assembly language uses mnemonic codes to write a program.

I need a Java program that handles the order list for if I were an online retailer. The program should contain a minimum of three classes:
Order Class
Display Class
Main Class
The Order Class that uses a queue to hold the orders in the order they were taken, and the queue should contain the customer's last name, order number, and order total cost. The Display Class needs to store a copy of the order queue in two arrays. Each array will contain the order list, but one will be sorted by name and the other sorted by order number. When an order is taken and stored in the Order Class the program will update the Display Class arrays automatically and sort them in descending order using quick sort and outputs the contents to the console upon each entry of new data.
There should be a Main Class that will handle operator data input and when an order is added or removed, the program will update the Order Class and Display Class. The end-user should be presented with a menu to add an order, remove an order and display the order list from the queue.

Using the knowledge in computational language in JAVA it is possible to write a code that handles the order list for if I were an online retailer.
