This document provides instructions for developing a first object-oriented program that defines a Computer class with attributes and methods, prompts the user for input about an existing and future computer, calculates the difference in attributes between the two instances, and prints the results. The assignment requires preparing a class diagram and pseudocode, writing the Computer class and program code, and submitting the design document, source files, and class files.

1. This assignment is to develop your first object-oriented
program. You will utilize classes, common data types, and
control structures. Following are the instructions.
Step 1: Define a Computer class that can be used to describe
your computer. The class must have at least two attributes. One
variable must be an integer data type and the other must be a
String data type. At least one method should be defined in your
class. Step 1a: Prepare a class diagram to illustrate your
Computer class. Copy to a Word document. Step 1b: Prepare
the source code that implements your Computer class. Give your
source code a filename of Computer.java.
Step 2: Prepare a program that utilizes your Computer class.
The requirements for the program include prompting the user
for input, making a calculation, and printing out the results.
Begin by creating your pseudocode for this program. Once you
have your pseudocode, copy it into your Word document. You
can now begin writing your program.
Your program should prompt the user for information about
their existing computer followed by information about a future,
more desirable computer. This means that your program will
create two instances of Computer class, the first instance
reflects the existing Computer, and the second instance reflects
the future Computer.
Use the Scanner class for obtaining input from the user
keyboard. The program must calculate the difference
(improvement) between the existing and future Computer class
variables of integer data type. For example, Computer class may
contain an integer variable named memory. The value of the
memory variable for the existing Computer instance may be 8,
while the value for this variable in the future Computer instance
may be 10. Calculating the difference would indicate an
improvement of 2.
Print to the screen the values for the existing computer class
and the desired computer class, along with the calculated
improvement.

2. Your assignment submittal should include your properly
commented Java source code for your Computer class as well as
for your program.
The first step should be to plan your program. Prepare a Word
document that shows your program plan description including
class diagram and your pseudocode defining program logic.
The second step should be to write the code based upon your
planning document.
Submit the Word design document, source code for Computer
class and for your program. Include both .class files.
