The document discusses naming conventions for code to make it more readable and maintainable. It recommends that names should reveal intent without needing comments, avoid disinformation by accurately describing what the code element represents, and use pronounceable and searchable names. Class names should be nouns, method names verbs, and accessor/mutator names should indicate their value and be prefixed with get/set. Context should be added through meaningful class, function and namespace names rather than encoding or prefixes. Overall, names should accurately convey what each code element represents at a glance.

Every project has a development standard.
Sometimes the standard is “if it was hard to write, it should be hard to maintain.”
Developing, and following, a corporate Best Practices standard will lead to continuity, maintainability, robustness, and pride.

Project #2
A Year in Gaming
(100 points)
For this project, you will create a digital portfolio of the games that were released on a certain year in gaming history. I will assign these years in class to avoid duplicates. Once you have your year, research the games that were released then.
You will then create a digital portrait of that year and group the games into categories based off what you notice about these games. Are there any similarities? Were there any particular world events that might have inspired these? (Games take years to make so you might look back over the previous two to five years for answers to this.) Were there any innovations to the gaming world that helped usher in these types of games? What consoles were popular at the time? What were the top selling games? Who are the game makers targeting as potential gamers with these games? Look for interesting trends, moments, and other facts to add depth to your project.
The answers to these questions and your groupings then need to be presented in a digital format. You can create a Powerpoint or Prezi presentation or you might choose to create a Tumblr, Instagram, Twitter, blog, WordPress, Pinterest, etc. account or even create a YouTube video for your year. If what you want to do isn’t listed- ask me.
Somewhere in the project, you must include the following:
· Your year
· Visual media
· Answers to above questions answered fully
· Games categorized
· Your name and class
· Organization
· A minimum of 1,200 words combined
· Creativity and originality
Important Dates
Tuesday, February 4th - Peer Workshop (digital or physical draft due in class)
First draft due to BlackBoard by 11:59pm
Thursday, February 13th- Final draft due to BlackBoard by 11:59pm
Either upload and attach your project or send me a link in the submission text box.
Your assigned year: ___________
· A procedure needs to store an inventory item’s name, height, and weight. The height may have a decimal place. The weight will be whole numbers only. Write the declaration statements to create the necessary procedure-level variables.
· Write an assignment statement that adds the contents of the sales1 variable to the contents of the sales2 variable and then assigns the sum to an existing variable named total Sales. All of the variables have the Decimal data type.
· Write the statement to declare a procedure-level named constant named TaxRate whose value is .2. The named constant should have the Double data type.
· Write the assignment statement to assign the string Dell to the string variable compType.
· Write the assignment statement to store the contents of the unitsTextBox in an Integer variable named numberOfUnits.
· Write the assignment statement to assign the contents of an Integer variable named numberOfUnits to the unitsLabel.
· Write the statement to declare a named constant named BonusRate whose value is .05. The named con ...

Object-oriented programming has gained some fame over the last few years. Its code flexibility and effective problem-solving nature are only two of the reasons for its sudden peak. Developers all-round consider OOP to be an important skill to have.
2. INTENTION REVEALING NAMES
The name of a variable, function, or class, should answer all
the big questions. It should tell you
why it exists
what it does
how it is used.
If a name requires a comment, then the name does not reveal
its intent.
int d; // elapsed time in days
Replacing with this
int elapsedTimeInDays;
3. AVOID DISINFORMATION
Programmers must avoid leaving false clues that change the
meaning of code.
We should avoid words vary from our intended meaning.
Do not refer to a grouping of accounts as an
accountList unless it’s actually a List.
The word list means something specific to
programmers
4. DIFFERENT NAMES
Beware of using names which vary in small ways
First Names should be different to spot the difference
How long does it take to spot the difference in
XYZControllerForEfficientHandlingOfStrings
And
XYZControllerForEfficientStorageOfStrings
Can you say the difference in these
getActiveAccount();
getActiveAccounts();
getActiveAccountInfo();
5. USE PRONOUNCEABLE NAMES
Humans are good at words.And words are, by definition,
pronounceable
class DtaRcrd102 {
private Date genymdhms;
private Date modymdhms;
private final String pszqint = "102";
/* ... */
};
What about this
class Customer {
private Date generationTimestamp;
private Date modificationTimestamp;;
private final String recordId = "102";
/* ... */
};
6. USE SEARCHABLE NAMES
Single-letter names and numeric constants have a problem in
that they are not easy to locate across a body of text.
One might easily search MAX_CLASSES_PER_STUDENT, but
the number 7 could be more troublesome.
Single-letter names can ONLY be used as local
variables inside short methods.
The length of a name should correspond to the size
of its scope
7. AVOID ENCODINGS
We have enough encodings to deal with without adding more
to our burden. Encoding type or scope information into names
simply adds an extra burden of deciphering
Avoid Hungarian Notation
Avoid Member Prefix
m_ will no longer needed
8. CLASS NAMES
Classes and objects should have noun or noun phrase names
like Customer, WikiPage, Account, and AddressParser.
Avoid words like Manager, Processor, Data, or Info in the
name of a class.
A class name should not be a verb
9. METHOD NAMES
Methods should have verb or verb phrase names like
postPayment, deletePage, or save.
Accessors, mutators, and predicates should be named for
their value and prefixed with get, set, and is accordingly
string name = employee.getName();
customer.setName("mike");
if (paycheck.isPosted())...
When constructors are overloaded, use static
factory methods with names that describe the
arguments.
10. PICK ONE WORD PER CONCEPT
Pick one word for one abstract concept and
stick with it.
It’s confusing to have fetch, retrieve, and get
as equivalent methods of different classes
11. ADD MEANINGFUL CONTEXT
There are a few names which are meaningful in and of
themselves—most are not.
Instead, you need to place names in context for your
reader by enclosing them in well-named classes,
functions, or namespaces.
When all else fails, then prefixing the name may be
necessary as a last resort.
14. DON’T ADD GRATUITOUS CONTEXT
In an imaginary application called “Gas
Station Deluxe,” it is a bad idea to prefix
every class with GSD.
The names accountAddress and
customerAddress are fine names for
instances of the class Address but could be
poor names for classes. Address is a fine
name for a class.
15. FINAL WORDS
People are also afraid of renaming things for fear
that some other developers will object.
Developers do not share that fear and find that we
are actually grateful when names change (for the
better).
Follow some of these rules and see whether you
don’t improve the readability of your code.
If you are maintaining someone else’s code, use
refactoring tools to help resolve these problems.
It will pay off in the short term and continue to pay
in the long run.
Complex fulcrumPoint = Complex.FromRealNumber(23.0);
is generally better than
Complex fulcrumPoint = new Complex(23.0);
Consider enforcing their use by making the corresponding constructors private
You type G and press the completion key and are rewarded with a mile-long list of every class in the system. Is that wise? Why make it hard for the IDE to help you?
